Adopters are - * encouraged to submit platform specific modifications to the Khronos - * group so that they can be included in future versions of this file. - * Please submit changes by filing pull requests or issues on - * the EGL Registry repository linked above. - * - * - * See the Implementer's Guidelines for information about where this file - * should be located on your system and for more details of its use: - * http://www.khronos.org/registry/implementers_guide.pdf - * - * This file should be included as - * #include - * by Khronos client API header files that use its types and defines. - * - * The types in khrplatform.h should only be used to define API-specific types. - * - * Types defined in khrplatform.h: - * khronos_int8_t signed 8 bit - * khronos_uint8_t unsigned 8 bit - * khronos_int16_t signed 16 bit - * khronos_uint16_t unsigned 16 bit - * khronos_int32_t signed 32 bit - * khronos_uint32_t unsigned 32 bit - * khronos_int64_t signed 64 bit - * khronos_uint64_t unsigned 64 bit - * khronos_intptr_t signed same number of bits as a pointer - * khronos_uintptr_t unsigned same number of bits as a pointer - * khronos_ssize_t signed size - * khronos_usize_t unsigned size - * khronos_float_t signed 32 bit floating point - * khronos_time_ns_t unsigned 64 bit time in nanoseconds - * khronos_utime_nanoseconds_t unsigned time interval or absolute time in - * nanoseconds - * khronos_stime_nanoseconds_t signed time interval in nanoseconds - * khronos_boolean_enum_t enumerated boolean type. This should - * only be used as a base type when a client API's boolean type is - * an enum. Client APIs which use an integer or other type for - * booleans cannot use this as the base type for their boolean. - * - * Tokens defined in khrplatform.h: - * - * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values. - * - * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0. - * KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0. - * - * Calling convention macros defined in this file: - * KHRONOS_APICALL - * KHRONOS_GLAD_API_PTR - * KHRONOS_APIATTRIBUTES - * - * These may be used in function prototypes as: - * - * KHRONOS_APICALL void KHRONOS_GLAD_API_PTR funcname( - * int arg1, - * int arg2) KHRONOS_APIATTRIBUTES; - */ - -#if defined(__SCITECH_SNAP__) && !defined(KHRONOS_STATIC) -# define KHRONOS_STATIC 1 -#endif - -/*------------------------------------------------------------------------- - * Definition of KHRONOS_APICALL - *------------------------------------------------------------------------- - * This precedes the return type of the function in the function prototype. - */ -#if defined(KHRONOS_STATIC) - /* If the preprocessor constant KHRONOS_STATIC is defined, make the - * header compatible with static linking. */ -# define KHRONOS_APICALL -#elif defined(_WIN32) -# define KHRONOS_APICALL __declspec(dllimport) -#elif defined (__SYMBIAN32__) -# define KHRONOS_APICALL IMPORT_C -#elif defined(__ANDROID__) -# define KHRONOS_APICALL __attribute__((visibility("default"))) -#else -# define KHRONOS_APICALL -#endif - -/*------------------------------------------------------------------------- - * Definition of KHRONOS_GLAD_API_PTR - *------------------------------------------------------------------------- - * This follows the return type of the function and precedes the function - * name in the function prototype. - */ -#if defined(_WIN32) && !defined(_WIN32_WCE) && !defined(__SCITECH_SNAP__) - /* Win32 but not WinCE */ -# define KHRONOS_GLAD_API_PTR __stdcall -#else -# define KHRONOS_GLAD_API_PTR -#endif - -/*------------------------------------------------------------------------- - * Definition of KHRONOS_APIATTRIBUTES - *------------------------------------------------------------------------- - * This follows the closing parenthesis of the function prototype arguments. - */ -#if defined (__ARMCC_2__) -#define KHRONOS_APIATTRIBUTES __softfp -#else -#define KHRONOS_APIATTRIBUTES -#endif - -/*------------------------------------------------------------------------- - * basic type definitions - *-----------------------------------------------------------------------*/ -#if (defined(__STDC_VERSION__) && __STDC_VERSION__ >= 199901L) || defined(__GNUC__) || defined(__SCO__) || defined(__USLC__) - - -/* - * Using - */ -#include -typedef int32_t khronos_int32_t; -typedef uint32_t khronos_uint32_t; -typedef int64_t khronos_int64_t; -typedef uint64_t khronos_uint64_t; -#define KHRONOS_SUPPORT_INT64 1 -#define KHRONOS_SUPPORT_FLOAT 1 - -#elif defined(__VMS ) || defined(__sgi) - -/* - * Using - */ -#include -typedef int32_t khronos_int32_t; -typedef uint32_t khronos_uint32_t; -typedef int64_t khronos_int64_t; -typedef uint64_t khronos_uint64_t; -#define KHRONOS_SUPPORT_INT64 1 -#define KHRONOS_SUPPORT_FLOAT 1 - -#elif defined(_WIN32) && !defined(__SCITECH_SNAP__) - -/* - * Win32 - */ -typedef __int32 khronos_int32_t; -typedef unsigned __int32 khronos_uint32_t; -typedef __int64 khronos_int64_t; -typedef unsigned __int64 khronos_uint64_t; -#define KHRONOS_SUPPORT_INT64 1 -#define KHRONOS_SUPPORT_FLOAT 1 - -#elif defined(__sun__) || defined(__digital__) - -/* - * Sun or Digital - */ -typedef int khronos_int32_t; -typedef unsigned int khronos_uint32_t; -#if defined(__arch64__) || defined(_LP64) -typedef long int khronos_int64_t; -typedef unsigned long int khronos_uint64_t; -#else -typedef long long int khronos_int64_t; -typedef unsigned long long int khronos_uint64_t; -#endif /* __arch64__ */ -#define KHRONOS_SUPPORT_INT64 1 -#define KHRONOS_SUPPORT_FLOAT 1 - -#elif 0 - -/* - * Hypothetical platform with no float or int64 support - */ -typedef int khronos_int32_t; -typedef unsigned int khronos_uint32_t; -#define KHRONOS_SUPPORT_INT64 0 -#define KHRONOS_SUPPORT_FLOAT 0 - -#else - -/* - * Generic fallback - */ -#include -typedef int32_t khronos_int32_t; -typedef uint32_t khronos_uint32_t; -typedef int64_t khronos_int64_t; -typedef uint64_t khronos_uint64_t; -#define KHRONOS_SUPPORT_INT64 1 -#define KHRONOS_SUPPORT_FLOAT 1 - -#endif - - -/* - * Types that are (so far) the same on all platforms - */ -typedef signed char khronos_int8_t; -typedef unsigned char khronos_uint8_t; -typedef signed short int khronos_int16_t; -typedef unsigned short int khronos_uint16_t; - -/* - * Types that differ between LLP64 and LP64 architectures - in LLP64, - * pointers are 64 bits, but 'long' is still 32 bits.

Introduction -=============== -miniaudio is a single file library for audio playback and capture. To use it, do the following in -one .c file: - - ```c - #define MINIAUDIO_IMPLEMENTATION - #include "miniaudio.h" - ``` - -You can do `#include "miniaudio.h"` in other parts of the program just like any other header. - -miniaudio includes both low level and high level APIs. The low level API is good for those who want -to do all of their mixing themselves and only require a light weight interface to the underlying -audio device. The high level API is good for those who have complex mixing and effect requirements. - -In miniaudio, objects are transparent structures. Unlike many other libraries, there are no handles -to opaque objects which means you need to allocate memory for objects yourself. In the examples -presented in this documentation you will often see objects declared on the stack. You need to be -careful when translating these examples to your own code so that you don't accidentally declare -your objects on the stack and then cause them to become invalid once the function returns. In -addition, you must ensure the memory address of your objects remain the same throughout their -lifetime. You therefore cannot be making copies of your objects. - -A config/init pattern is used throughout the entire library. The idea is that you set up a config -object and pass that into the initialization routine. The advantage to this system is that the -config object can be initialized with logical defaults and new properties added to it without -breaking the API. The config object can be allocated on the stack and does not need to be -maintained after initialization of the corresponding object. - - -1.1. Low Level API ------------------- -The low level API gives you access to the raw audio data of an audio device. It supports playback, -capture, full-duplex and loopback (WASAPI only). You can enumerate over devices to determine which -physical device(s) you want to connect to. - -The low level API uses the concept of a "device" as the abstraction for physical devices. The idea -is that you choose a physical device to emit or capture audio from, and then move data to/from the -device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a -callback which you specify when initializing the device. - -When initializing the device you first need to configure it. The device configuration allows you to -specify things like the format of the data delivered via the callback, the size of the internal -buffer and the ID of the device you want to emit or capture audio from. - -Once you have the device configuration set up you can initialize the device. When initializing a -device you need to allocate memory for the device object beforehand. This gives the application -complete control over how the memory is allocated. In the example below we initialize a playback -device on the stack, but you could allocate it on the heap if that suits your situation better. - - ```c - void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) - { - // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both - // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than - // frameCount frames. - } - - int main() - { - ma_device_config config = ma_device_config_init(ma_device_type_playback); - config.playback.format = ma_format_f32; // Set to ma_format_unknown to use the device's native format. - config.playback.channels = 2; // Set to 0 to use the device's native channel count. - config.sampleRate = 48000; // Set to 0 to use the device's native sample rate. - config.dataCallback = data_callback; // This function will be called when miniaudio needs more data. - config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData). - - ma_device device; - if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) { - return -1; // Failed to initialize the device. - } - - ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually. - - // Do something here. Probably your program's main loop. - - ma_device_uninit(&device); - return 0; - } - ``` - -In the example above, `data_callback()` is where audio data is written and read from the device. -The idea is in playback mode you cause sound to be emitted from the speakers by writing audio data -to the output buffer (`pOutput` in the example). In capture mode you read data from the input -buffer (`pInput`) to extract sound captured by the microphone. The `frameCount` parameter tells you -how many frames can be written to the output buffer and read from the input buffer. A "frame" is -one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 -samples: one for the left, one for the right. The channel count is defined by the device config. -The size in bytes of an individual sample is defined by the sample format which is also specified -in the device config. Multi-channel audio data is always interleaved, which means the samples for -each frame are stored next to each other in memory. For example, in a stereo stream the first pair -of samples will be the left and right samples for the first frame, the second pair of samples will -be the left and right samples for the second frame, etc. - -The configuration of the device is defined by the `ma_device_config` structure. The config object -is always initialized with `ma_device_config_init()`. It's important to always initialize the -config with this function as it initializes it with logical defaults and ensures your program -doesn't break when new members are added to the `ma_device_config` structure. The example above -uses a fairly simple and standard device configuration. The call to `ma_device_config_init()` takes -a single parameter, which is whether or not the device is a playback, capture, duplex or loopback -device (loopback devices are not supported on all backends). The `config.playback.format` member -sets the sample format which can be one of the following (all formats are native-endian): - - +---------------+----------------------------------------+---------------------------+ - | Symbol | Description | Range | - +---------------+----------------------------------------+---------------------------+ - | ma_format_f32 | 32-bit floating point | [-1, 1] | - | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | - | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | - | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | - | ma_format_u8 | 8-bit unsigned integer | [0, 255] | - +---------------+----------------------------------------+---------------------------+ - -The `config.playback.channels` member sets the number of channels to use with the device. The -channel count cannot exceed MA_MAX_CHANNELS. The `config.sampleRate` member sets the sample rate -(which must be the same for both playback and capture in full-duplex configurations). This is -usually set to 44100 or 48000, but can be set to anything. It's recommended to keep this between -8000 and 384000, however. - -Note that leaving the format, channel count and/or sample rate at their default values will result -in the internal device's native configuration being used which is useful if you want to avoid the -overhead of miniaudio's automatic data conversion. - -In addition to the sample format, channel count and sample rate, the data callback and user data -pointer are also set via the config. The user data pointer is not passed into the callback as a -parameter, but is instead set to the `pUserData` member of `ma_device` which you can access -directly since all miniaudio structures are transparent. - -Initializing the device is done with `ma_device_init()`. This will return a result code telling you -what went wrong, if anything. On success it will return `MA_SUCCESS`. After initialization is -complete the device will be in a stopped state. To start it, use `ma_device_start()`. -Uninitializing the device will stop it, which is what the example above does, but you can also stop -the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again. -Note that it's important to never stop or start the device from inside the callback. This will -result in a deadlock. Instead you set a variable or signal an event indicating that the device -needs to stop and handle it in a different thread. The following APIs must never be called inside -the callback: - - ```c - ma_device_init() - ma_device_init_ex() - ma_device_uninit() - ma_device_start() - ma_device_stop() - ``` - -You must never try uninitializing and reinitializing a device inside the callback. You must also -never try to stop and start it from inside the callback. There are a few other things you shouldn't -do in the callback depending on your requirements, however this isn't so much a thread-safety -thing, but rather a real-time processing thing which is beyond the scope of this introduction. - -The example above demonstrates the initialization of a playback device, but it works exactly the -same for capture. All you need to do is change the device type from `ma_device_type_playback` to -`ma_device_type_capture` when setting up the config, like so: - - ```c - ma_device_config config = ma_device_config_init(ma_device_type_capture); - config.capture.format = MY_FORMAT; - config.capture.channels = MY_CHANNEL_COUNT; - ``` - -In the data callback you just read from the input buffer (`pInput` in the example above) and leave -the output buffer alone (it will be set to NULL when the device type is set to -`ma_device_type_capture`). - -These are the available device types and how you should handle the buffers in the callback: - - +-------------------------+--------------------------------------------------------+ - | Device Type | Callback Behavior | - +-------------------------+--------------------------------------------------------+ - | ma_device_type_playback | Write to output buffer, leave input buffer untouched. | - | ma_device_type_capture | Read from input buffer, leave output buffer untouched. | - | ma_device_type_duplex | Read from input buffer, write to output buffer. | - | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. | - +-------------------------+--------------------------------------------------------+ - -You will notice in the example above that the sample format and channel count is specified -separately for playback and capture. This is to support different data formats between the playback -and capture devices in a full-duplex system. An example may be that you want to capture audio data -as a monaural stream (one channel), but output sound to a stereo speaker system. Note that if you -use different formats between playback and capture in a full-duplex configuration you will need to -convert the data yourself. There are functions available to help you do this which will be -explained later. - -The example above did not specify a physical device to connect to which means it will use the -operating system's default device. If you have multiple physical devices connected and you want to -use a specific one you will need to specify the device ID in the configuration, like so: - - ```c - config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device. - config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device. - ``` - -To retrieve the device ID you will need to perform device enumeration, however this requires the -use of a new concept called the "context". Conceptually speaking the context sits above the device. -There is one context to many devices. The purpose of the context is to represent the backend at a -more global level and to perform operations outside the scope of an individual device. Mainly it is -used for performing run-time linking against backend libraries, initializing backends and -enumerating devices. The example below shows how to enumerate devices. - - ```c - ma_context context; - if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) { - // Error. - } - - ma_device_info* pPlaybackInfos; - ma_uint32 playbackCount; - ma_device_info* pCaptureInfos; - ma_uint32 captureCount; - if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) { - // Error. - } - - // Loop over each device info and do something with it. Here we just print the name with their index. You may want - // to give the user the opportunity to choose which device they'd prefer. - for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) { - printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name); - } - - ma_device_config config = ma_device_config_init(ma_device_type_playback); - config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id; - config.playback.format = MY_FORMAT; - config.playback.channels = MY_CHANNEL_COUNT; - config.sampleRate = MY_SAMPLE_RATE; - config.dataCallback = data_callback; - config.pUserData = pMyCustomData; - - ma_device device; - if (ma_device_init(&context, &config, &device) != MA_SUCCESS) { - // Error - } - - ... - - ma_device_uninit(&device); - ma_context_uninit(&context); - ``` - -The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. -The first parameter is a pointer to a list of `ma_backend` values which are used to override the -default backend priorities. When this is NULL, as in this example, miniaudio's default priorities -are used. The second parameter is the number of backends listed in the array pointed to by the -first parameter. The third parameter is a pointer to a `ma_context_config` object which can be -NULL, in which case defaults are used. The context configuration is used for setting the logging -callback, custom memory allocation callbacks, user-defined data and some backend-specific -configurations. - -Once the context has been initialized you can enumerate devices. In the example above we use the -simpler `ma_context_get_devices()`, however you can also use a callback for handling devices by -using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer -to a pointer that will, upon output, be set to a pointer to a buffer containing a list of -`ma_device_info` structures. You also provide a pointer to an unsigned integer that will receive -the number of items in the returned buffer. Do not free the returned buffers as their memory is -managed internally by miniaudio. - -The `ma_device_info` structure contains an `id` member which is the ID you pass to the device -config. It also contains the name of the device which is useful for presenting a list of devices -to the user via the UI. - -When creating your own context you will want to pass it to `ma_device_init()` when initializing the -device. Passing in NULL, like we do in the first example, will result in miniaudio creating the -context for you, which you don't want to do since you've already created a context. Note that -internally the context is only tracked by it's pointer which means you must not change the location -of the `ma_context` object. If this is an issue, consider using `malloc()` to allocate memory for -the context. - - -1.2. High Level API -------------------- -The high level API consists of three main parts: - - * Resource management for loading and streaming sounds. - * A node graph for advanced mixing and effect processing. - * A high level "engine" that wraps around the resource manager and node graph. - -The resource manager (`ma_resource_manager`) is used for loading sounds. It supports loading sounds -fully into memory and also streaming. It will also deal with reference counting for you which -avoids the same sound being loaded multiple times. - -The node graph is used for mixing and effect processing. The idea is that you connect a number of -nodes into the graph by connecting each node's outputs to another node's inputs. Each node can -implement it's own effect. By chaining nodes together, advanced mixing and effect processing can -be achieved. - -The engine encapsulates both the resource manager and the node graph to create a simple, easy to -use high level API. The resource manager and node graph APIs are covered in more later sections of -this manual. - -The code below shows how you can initialize an engine using it's default configuration. - - ```c - ma_result result; - ma_engine engine; - - result = ma_engine_init(NULL, &engine); - if (result != MA_SUCCESS) { - return result; // Failed to initialize the engine. - } - ``` - -This creates an engine instance which will initialize a device internally which you can access with -`ma_engine_get_device()`. It will also initialize a resource manager for you which can be accessed -with `ma_engine_get_resource_manager()`. The engine itself is a node graph (`ma_node_graph`) which -means you can pass a pointer to the engine object into any of the `ma_node_graph` APIs (with a -cast). Alternatively, you can use `ma_engine_get_node_graph()` instead of a cast. - -Note that all objects in miniaudio, including the `ma_engine` object in the example above, are -transparent structures. There are no handles to opaque structures in miniaudio which means you need -to be mindful of how you declare them. In the example above we are declaring it on the stack, but -this will result in the struct being invalidated once the function encapsulating it returns. If -allocating the engine on the heap is more appropriate, you can easily do so with a standard call -to `malloc()` or whatever heap allocation routine you like: - - ```c - ma_engine* pEngine = malloc(sizeof(*pEngine)); - ``` - -The `ma_engine` API uses the same config/init pattern used all throughout miniaudio. To configure -an engine, you can fill out a `ma_engine_config` object and pass it into the first parameter of -`ma_engine_init()`: - - ```c - ma_result result; - ma_engine engine; - ma_engine_config engineConfig; - - engineConfig = ma_engine_config_init(); - engineConfig.pResourceManager = &myCustomResourceManager; // <-- Initialized as some earlier stage. - - result = ma_engine_init(&engineConfig, &engine); - if (result != MA_SUCCESS) { - return result; - } - ``` - -This creates an engine instance using a custom config. In this particular example it's showing how -you can specify a custom resource manager rather than having the engine initialize one internally. -This is particularly useful if you want to have multiple engine's share the same resource manager. - -The engine must be uninitialized with `ma_engine_uninit()` when it's no longer needed. - -By default the engine will be started, but nothing will be playing because no sounds have been -initialized. The easiest but least flexible way of playing a sound is like so: - - ```c - ma_engine_play_sound(&engine, "my_sound.wav", NULL); - ``` - -This plays what miniaudio calls an "inline" sound. It plays the sound once, and then puts the -internal sound up for recycling. The last parameter is used to specify which sound group the sound -should be associated with which will be explained later. This particular way of playing a sound is -simple, but lacks flexibility and features. A more flexible way of playing a sound is to first -initialize a sound: - - ```c - ma_result result; - ma_sound sound; - - result = ma_sound_init_from_file(&engine, "my_sound.wav", 0, NULL, NULL, &sound); - if (result != MA_SUCCESS) { - return result; - } - - ma_sound_start(&sound); - ``` - -This returns a `ma_sound` object which represents a single instance of the specified sound file. If -you want to play the same file multiple times simultaneously, you need to create one sound for each -instance. - -Sounds should be uninitialized with `ma_sound_uninit()`. - -Sounds are not started by default. Start a sound with `ma_sound_start()` and stop it with -`ma_sound_stop()`. When a sound is stopped, it is not rewound to the start. Use -`ma_sound_seek_to_pcm_frame(&sound, 0)` to seek back to the start of a sound. By default, starting -and stopping sounds happens immediately, but sometimes it might be convenient to schedule the sound -the be started and/or stopped at a specific time. This can be done with the following functions: - - ```c - ma_sound_set_start_time_in_pcm_frames() - ma_sound_set_start_time_in_milliseconds() - ma_sound_set_stop_time_in_pcm_frames() - ma_sound_set_stop_time_in_milliseconds() - ``` - -The start/stop time needs to be specified based on the absolute timer which is controlled by the -engine. The current global time time in PCM frames can be retrieved with -`ma_engine_get_time_in_pcm_frames()`. The engine's global time can be changed with -`ma_engine_set_time_in_pcm_frames()` for synchronization purposes if required. Note that scheduling -a start time still requires an explicit call to `ma_sound_start()` before anything will play: - - ```c - ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2); - ma_sound_start(&sound); - ``` - -The third parameter of `ma_sound_init_from_file()` is a set of flags that control how the sound be -loaded and a few options on which features should be enabled for that sound. By default, the sound -is synchronously loaded fully into memory straight from the file system without any kind of -decoding. If you want to decode the sound before storing it in memory, you need to specify the -`MA_SOUND_FLAG_DECODE` flag. This is useful if you want to incur the cost of decoding at an earlier -stage, such as a loading stage. Without this option, decoding will happen dynamically at mixing -time which might be too expensive on the audio thread. - -If you want to load the sound asynchronously, you can specify the `MA_SOUND_FLAG_ASYNC` flag. This -will result in `ma_sound_init_from_file()` returning quickly, but the sound will not start playing -until the sound has had some audio decoded. - -The fourth parameter is a pointer to sound group. A sound group is used as a mechanism to organise -sounds into groups which have their own effect processing and volume control. An example is a game -which might have separate groups for sfx, voice and music. Each of these groups have their own -independent volume control. Use `ma_sound_group_init()` or `ma_sound_group_init_ex()` to initialize -a sound group. - -Sounds and sound groups are nodes in the engine's node graph and can be plugged into any `ma_node` -API. This makes it possible to connect sounds and sound groups to effect nodes to produce complex -effect chains. - -A sound can have it's volume changed with `ma_sound_set_volume()`. If you prefer decibel volume -control you can use `ma_volume_db_to_linear()` to convert from decibel representation to linear. - -Panning and pitching is supported with `ma_sound_set_pan()` and `ma_sound_set_pitch()`. If you know -a sound will never have it's pitch changed with `ma_sound_set_pitch()` or via the doppler effect, -you can specify the `MA_SOUND_FLAG_NO_PITCH` flag when initializing the sound for an optimization. - -By default, sounds and sound groups have spatialization enabled. If you don't ever want to -spatialize your sounds, initialize the sound with the `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. The -spatialization model is fairly simple and is roughly on feature parity with OpenAL. HRTF and -environmental occlusion are not currently supported, but planned for the future. The supported -features include: - - * Sound and listener positioning and orientation with cones - * Attenuation models: none, inverse, linear and exponential - * Doppler effect - -Sounds can be faded in and out with `ma_sound_set_fade_in_pcm_frames()`. - -To check if a sound is currently playing, you can use `ma_sound_is_playing()`. To check if a sound -is at the end, use `ma_sound_at_end()`. Looping of a sound can be controlled with -`ma_sound_set_looping()`. Use `ma_sound_is_looping()` to check whether or not the sound is looping. - - - -2. Building -=========== -miniaudio should work cleanly out of the box without the need to download or install any -dependencies. See below for platform-specific details. - -Note that GCC and Clang require `-msse2`, `-mavx2`, etc. for SIMD optimizations. - -If you get errors about undefined references to `__sync_val_compare_and_swap_8`, `__atomic_load_8`, -etc. you need to link with `-latomic`. - - -2.1. Windows ------------- -The Windows build should compile cleanly on all popular compilers without the need to configure any -include paths nor link to any libraries. - -The UWP build may require linking to mmdevapi.lib if you get errors about an unresolved external -symbol for `ActivateAudioInterfaceAsync()`. - - -2.2. macOS and iOS ------------------- -The macOS build should compile cleanly without the need to download any dependencies nor link to -any libraries or frameworks. The iOS build needs to be compiled as Objective-C and will need to -link the relevant frameworks but should compile cleanly out of the box with Xcode. Compiling -through the command line requires linking to `-lpthread` and `-lm`. - -Due to the way miniaudio links to frameworks at runtime, your application may not pass Apple's -notarization process. To fix this there are two options. The first is to use the -`MA_NO_RUNTIME_LINKING` option, like so: - - ```c - #ifdef __APPLE__ - #define MA_NO_RUNTIME_LINKING - #endif - #define MINIAUDIO_IMPLEMENTATION - #include "miniaudio.h" - ``` - -This will require linking with `-framework CoreFoundation -framework CoreAudio -framework AudioToolbox`. -If you get errors about AudioToolbox, try with `-framework AudioUnit` instead. You may get this when -using older versions of iOS. Alternatively, if you would rather keep using runtime linking you can -add the following to your entitlements.xcent file: - - ``` - com.apple.security.cs.allow-dyld-environment-variables - - com.apple.security.cs.allow-unsigned-executable-memory - - ``` - -See this discussion for more info: https://github.com/mackron/miniaudio/issues/203. - - -2.3. Linux ----------- -The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any -development packages. You may need to link with `-latomic` if you're compiling for 32-bit ARM. - - -2.4. BSD --------- -The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses -sndio and FreeBSD uses OSS. You may need to link with `-latomic` if you're compiling for 32-bit -ARM. - - -2.5. Android ------------- -AAudio is the highest priority backend on Android. This should work out of the box without needing -any kind of compiler configuration. Support for AAudio starts with Android 8 which means older -versions will fall back to OpenSL|ES which requires API level 16+. - -There have been reports that the OpenSL|ES backend fails to initialize on some Android based -devices due to `dlopen()` failing to open "libOpenSLES.so". If this happens on your platform -you'll need to disable run-time linking with `MA_NO_RUNTIME_LINKING` and link with -lOpenSLES. - - -2.6. Emscripten ---------------- -The Emscripten build emits Web Audio JavaScript directly and should compile cleanly out of the box. -You cannot use `-std=c*` compiler flags, nor `-ansi`. - -You can enable the use of AudioWorkets by defining `MA_ENABLE_AUDIO_WORKLETS` and then compiling -with the following options: - - -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY - -An example for compiling with AudioWorklet support might look like this: - - emcc program.c -o bin/program.html -DMA_ENABLE_AUDIO_WORKLETS -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY - -To run locally, you'll need to use emrun: - - emrun bin/program.html - - - -2.7.

Definitions -============== -This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity -in the use of terms throughout the audio space, so this section is intended to clarify how miniaudio -uses each term. - -3.1. Sample ------------ -A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit -floating point number. - -3.2. Frame / PCM Frame ----------------------- -A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 -samples, a mono frame is 1 sample, a 5.1 surround sound frame is 6 samples, etc. The terms "frame" -and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. -If ever miniaudio needs to refer to a compressed frame, such as a FLAC frame, it will always -clarify what it's referring to with something like "FLAC frame". - -3.3. Channel ------------- -A stream of monaural audio that is emitted from an individual speaker in a speaker system, or -received from an individual microphone in a microphone system. A stereo stream has two channels (a -left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio -systems refer to a channel as a complex audio stream that's mixed with other channels to produce -the final mix - this is completely different to miniaudio's use of the term "channel" and should -not be confused. - -3.4. Sample Rate ----------------- -The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number -of PCM frames that are processed per second. - -3.5. Formats ------------- -Throughout miniaudio you will see references to different sample formats: - - +---------------+----------------------------------------+---------------------------+ - | Symbol | Description | Range | - +---------------+----------------------------------------+---------------------------+ - | ma_format_f32 | 32-bit floating point | [-1, 1] | - | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | - | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | - | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | - | ma_format_u8 | 8-bit unsigned integer | [0, 255] | - +---------------+----------------------------------------+---------------------------+ - -All formats are native-endian. - - - -4. Data Sources -=============== -The data source abstraction in miniaudio is used for retrieving audio data from some source. A few -examples include `ma_decoder`, `ma_noise` and `ma_waveform`. You will need to be familiar with data -sources in order to make sense of some of the higher level concepts in miniaudio. - -The `ma_data_source` API is a generic interface for reading from a data source. Any object that -implements the data source interface can be plugged into any `ma_data_source` function. - -To read data from a data source: - - ```c - ma_result result; - ma_uint64 framesRead; - - result = ma_data_source_read_pcm_frames(pDataSource, pFramesOut, frameCount, &framesRead); - if (result != MA_SUCCESS) { - return result; // Failed to read data from the data source. - } - ``` - -If you don't need the number of frames that were successfully read you can pass in `NULL` to the -`pFramesRead` parameter. If this returns a value less than the number of frames requested it means -the end of the file has been reached. `MA_AT_END` will be returned only when the number of frames -read is 0. - -When calling any data source function, with the exception of `ma_data_source_init()` and -`ma_data_source_uninit()`, you can pass in any object that implements a data source. For example, -you could plug in a decoder like so: - - ```c - ma_result result; - ma_uint64 framesRead; - ma_decoder decoder; // <-- This would be initialized with `ma_decoder_init_*()`. - - result = ma_data_source_read_pcm_frames(&decoder, pFramesOut, frameCount, &framesRead); - if (result != MA_SUCCESS) { - return result; // Failed to read data from the decoder. - } - ``` - -If you want to seek forward you can pass in `NULL` to the `pFramesOut` parameter. Alternatively you -can use `ma_data_source_seek_pcm_frames()`. - -To seek to a specific PCM frame: - - ```c - result = ma_data_source_seek_to_pcm_frame(pDataSource, frameIndex); - if (result != MA_SUCCESS) { - return result; // Failed to seek to PCM frame. - } - ``` - -You can retrieve the total length of a data source in PCM frames, but note that some data sources -may not have the notion of a length, such as noise and waveforms, and others may just not have a -way of determining the length such as some decoders. To retrieve the length: - - ```c - ma_uint64 length; - - result = ma_data_source_get_length_in_pcm_frames(pDataSource, &length); - if (result != MA_SUCCESS) { - return result; // Failed to retrieve the length. - } - ``` - -Care should be taken when retrieving the length of a data source where the underlying decoder is -pulling data from a data stream with an undefined length, such as internet radio or some kind of -broadcast. If you do this, `ma_data_source_get_length_in_pcm_frames()` may never return. - -The current position of the cursor in PCM frames can also be retrieved: - - ```c - ma_uint64 cursor; - - result = ma_data_source_get_cursor_in_pcm_frames(pDataSource, &cursor); - if (result != MA_SUCCESS) { - return result; // Failed to retrieve the cursor. - } - ``` - -You will often need to know the data format that will be returned after reading. This can be -retrieved like so: - - ```c - ma_format format; - ma_uint32 channels; - ma_uint32 sampleRate; - ma_channel channelMap[MA_MAX_CHANNELS]; - - result = ma_data_source_get_data_format(pDataSource, &format, &channels, &sampleRate, channelMap, MA_MAX_CHANNELS); - if (result != MA_SUCCESS) { - return result; // Failed to retrieve data format. - } - ``` - -If you do not need a specific data format property, just pass in NULL to the respective parameter. - -There may be cases where you want to implement something like a sound bank where you only want to -read data within a certain range of the underlying data. To do this you can use a range: - - ```c - result = ma_data_source_set_range_in_pcm_frames(pDataSource, rangeBegInFrames, rangeEndInFrames); - if (result != MA_SUCCESS) { - return result; // Failed to set the range. - } - ``` - -This is useful if you have a sound bank where many sounds are stored in the same file and you want -the data source to only play one of those sub-sounds. Note that once the range is set, everything -that takes a position, such as cursors and loop points, should always be relatvie to the start of -the range. When the range is set, any previously defined loop point will be reset. - -Custom loop points can also be used with data sources. By default, data sources will loop after -they reach the end of the data source, but if you need to loop at a specific location, you can do -the following: - - ```c - result = ma_data_set_loop_point_in_pcm_frames(pDataSource, loopBegInFrames, loopEndInFrames); - if (result != MA_SUCCESS) { - return result; // Failed to set the loop point. - } - ``` - -The loop point is relative to the current range. - -It's sometimes useful to chain data sources together so that a seamless transition can be achieved. -To do this, you can use chaining: - - ```c - ma_decoder decoder1; - ma_decoder decoder2; - - // ... initialize decoders with ma_decoder_init_*() ... - - result = ma_data_source_set_next(&decoder1, &decoder2); - if (result != MA_SUCCESS) { - return result; // Failed to set the next data source. - } - - result = ma_data_source_read_pcm_frames(&decoder1, pFramesOut, frameCount, pFramesRead); - if (result != MA_SUCCESS) { - return result; // Failed to read from the decoder. - } - ``` - -In the example above we're using decoders. When reading from a chain, you always want to read from -the top level data source in the chain. In the example above, `decoder1` is the top level data -source in the chain. When `decoder1` reaches the end, `decoder2` will start seamlessly without any -gaps. - -Note that when looping is enabled, only the current data source will be looped. You can loop the -entire chain by linking in a loop like so: - - ```c - ma_data_source_set_next(&decoder1, &decoder2); // decoder1 -> decoder2 - ma_data_source_set_next(&decoder2, &decoder1); // decoder2 -> decoder1 (loop back to the start). - ``` - -Note that setting up chaining is not thread safe, so care needs to be taken if you're dynamically -changing links while the audio thread is in the middle of reading. - -Do not use `ma_decoder_seek_to_pcm_frame()` as a means to reuse a data source to play multiple -instances of the same sound simultaneously. This can be extremely inefficient depending on the type -of data source and can result in glitching due to subtle changes to the state of internal filters. -Instead, initialize multiple data sources for each instance. - - -4.1. Custom Data Sources ------------------------- -You can implement a custom data source by implementing the functions in `ma_data_source_vtable`. -Your custom object must have `ma_data_source_base` as it's first member: - - ```c - struct my_data_source - { - ma_data_source_base base; - ... - }; - ``` - -In your initialization routine, you need to call `ma_data_source_init()` in order to set up the -base object (`ma_data_source_base`): - - ```c - static ma_result my_data_source_read(ma_data_source* pDataSource, void* pFramesOut, ma_uint64 frameCount, ma_uint64* pFramesRead) - { - // Read data here. Output in the same format returned by my_data_source_get_data_format(). - } - - static ma_result my_data_source_seek(ma_data_source* pDataSource, ma_uint64 frameIndex) - { - // Seek to a specific PCM frame here.

It's up to the custom data source itself to call these within their own -init/uninit functions. - - - -5. Engine -========= -The `ma_engine` API is a high level API for managing and mixing sounds and effect processing. The -`ma_engine` object encapsulates a resource manager and a node graph, both of which will be -explained in more detail later. - -Sounds are called `ma_sound` and are created from an engine. Sounds can be associated with a mixing -group called `ma_sound_group` which are also created from the engine. Both `ma_sound` and -`ma_sound_group` objects are nodes within the engine's node graph. - -When the engine is initialized, it will normally create a device internally. If you would rather -manage the device yourself, you can do so and just pass a pointer to it via the engine config when -you initialize the engine. You can also just use the engine without a device, which again can be -configured via the engine config. - -The most basic way to initialize the engine is with a default config, like so: - - ```c - ma_result result; - ma_engine engine; - - result = ma_engine_init(NULL, &engine); - if (result != MA_SUCCESS) { - return result; // Failed to initialize the engine. - } - ``` - -This will result in the engine initializing a playback device using the operating system's default -device. This will be sufficient for many use cases, but if you need more flexibility you'll want to -configure the engine with an engine config: - - ```c - ma_result result; - ma_engine engine; - ma_engine_config engineConfig; - - engineConfig = ma_engine_config_init(); - engineConfig.pDevice = &myDevice; - - result = ma_engine_init(&engineConfig, &engine); - if (result != MA_SUCCESS) { - return result; // Failed to initialize the engine. - } - ``` - -In the example above we're passing in a pre-initialized device. Since the caller is the one in -control of the device's data callback, it's their responsibility to manually call -`ma_engine_read_pcm_frames()` from inside their data callback: - - ```c - void playback_data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) - { - ma_engine_read_pcm_frames(&g_Engine, pOutput, frameCount, NULL); - } - ``` - -You can also use the engine independent of a device entirely: - - ```c - ma_result result; - ma_engine engine; - ma_engine_config engineConfig; - - engineConfig = ma_engine_config_init(); - engineConfig.noDevice = MA_TRUE; - engineConfig.channels = 2; // Must be set when not using a device. - engineConfig.sampleRate = 48000; // Must be set when not using a device. - - result = ma_engine_init(&engineConfig, &engine); - if (result != MA_SUCCESS) { - return result; // Failed to initialize the engine. - } - ``` - -Note that when you're not using a device, you must set the channel count and sample rate in the -config or else miniaudio won't know what to use (miniaudio will use the device to determine this -normally). When not using a device, you need to use `ma_engine_read_pcm_frames()` to process audio -data from the engine. This kind of setup is useful if you want to do something like offline -processing or want to use a different audio system for playback such as SDL. - -When a sound is loaded it goes through a resource manager. By default the engine will initialize a -resource manager internally, but you can also specify a pre-initialized resource manager: - - ```c - ma_result result; - ma_engine engine1; - ma_engine engine2; - ma_engine_config engineConfig; - - engineConfig = ma_engine_config_init(); - engineConfig.pResourceManager = &myResourceManager; - - ma_engine_init(&engineConfig, &engine1); - ma_engine_init(&engineConfig, &engine2); - ``` - -In this example we are initializing two engines, both of which are sharing the same resource -manager. This is especially useful for saving memory when loading the same file across multiple -engines. If you were not to use a shared resource manager, each engine instance would use their own -which would result in any sounds that are used between both engine's being loaded twice. By using -a shared resource manager, it would only be loaded once. Using multiple engine's is useful when you -need to output to multiple playback devices, such as in a local multiplayer game where each player -is using their own set of headphones. - -By default an engine will be in a started state. To make it so the engine is not automatically -started you can configure it as such: - - ```c - engineConfig.noAutoStart = MA_TRUE; - - // The engine will need to be started manually. - ma_engine_start(&engine); - - // Later on the engine can be stopped with ma_engine_stop(). - ma_engine_stop(&engine); - ``` - -The concept of starting or stopping an engine is only relevant when using the engine with a -device. Attempting to start or stop an engine that is not associated with a device will result in -`MA_INVALID_OPERATION`. - -The master volume of the engine can be controlled with `ma_engine_set_volume()` which takes a -linear scale, with 0 resulting in silence and anything above 1 resulting in amplification. If you -prefer decibel based volume control, use `ma_volume_db_to_linear()` to convert from dB to linear. - -When a sound is spatialized, it is done so relative to a listener. An engine can be configured to -have multiple listeners which can be configured via the config: - - ```c - engineConfig.listenerCount = 2; - ``` - -The maximum number of listeners is restricted to `MA_ENGINE_MAX_LISTENERS`. By default, when a -sound is spatialized, it will be done so relative to the closest listener. You can also pin a sound -to a specific listener which will be explained later. Listener's have a position, direction, cone, -and velocity (for doppler effect). A listener is referenced by an index, the meaning of which is up -to the caller (the index is 0 based and cannot go beyond the listener count, minus 1). The -position, direction and velocity are all specified in absolute terms: - - ```c - ma_engine_listener_set_position(&engine, listenerIndex, worldPosX, worldPosY, worldPosZ); - ``` - -The direction of the listener represents it's forward vector. The listener's up vector can also be -specified and defaults to +1 on the Y axis. - - ```c - ma_engine_listener_set_direction(&engine, listenerIndex, forwardX, forwardY, forwardZ); - ma_engine_listener_set_world_up(&engine, listenerIndex, 0, 1, 0); - ``` - -The engine supports directional attenuation. The listener can have a cone the controls how sound is -attenuated based on the listener's direction. When a sound is between the inner and outer cones, it -will be attenuated between 1 and the cone's outer gain: - - ```c - ma_engine_listener_set_cone(&engine, listenerIndex, innerAngleInRadians, outerAngleInRadians, outerGain); - ``` - -When a sound is inside the inner code, no directional attenuation is applied. When the sound is -outside of the outer cone, the attenuation will be set to `outerGain` in the example above. When -the sound is in between the inner and outer cones, the attenuation will be interpolated between 1 -and the outer gain. - -The engine's coordinate system follows the OpenGL coordinate system where positive X points right, -positive Y points up and negative Z points forward. - -The simplest and least flexible way to play a sound is like so: - - ```c - ma_engine_play_sound(&engine, "my_sound.wav", pGroup); - ``` - -This is a "fire and forget" style of function. The engine will manage the `ma_sound` object -internally. When the sound finishes playing, it'll be put up for recycling. For more flexibility -you'll want to initialize a sound object: - - ```c - ma_sound sound; - - result = ma_sound_init_from_file(&engine, "my_sound.wav", flags, pGroup, NULL, &sound); - if (result != MA_SUCCESS) { - return result; // Failed to load sound. - } - ``` - -Sounds need to be uninitialized with `ma_sound_uninit()`. - -The example above loads a sound from a file. If the resource manager has been disabled you will not -be able to use this function and instead you'll need to initialize a sound directly from a data -source: - - ```c - ma_sound sound; - - result = ma_sound_init_from_data_source(&engine, &dataSource, flags, pGroup, &sound); - if (result != MA_SUCCESS) { - return result; - } - ``` - -Each `ma_sound` object represents a single instance of the sound. If you want to play the same -sound multiple times at the same time, you need to initialize a separate `ma_sound` object. - -For the most flexibility when initializing sounds, use `ma_sound_init_ex()`. This uses miniaudio's -standard config/init pattern: - - ```c - ma_sound sound; - ma_sound_config soundConfig; - - soundConfig = ma_sound_config_init(); - soundConfig.pFilePath = NULL; // Set this to load from a file path. - soundConfig.pDataSource = NULL; // Set this to initialize from an existing data source. - soundConfig.pInitialAttachment = &someNodeInTheNodeGraph; - soundConfig.initialAttachmentInputBusIndex = 0; - soundConfig.channelsIn = 1; - soundConfig.channelsOut = 0; // Set to 0 to use the engine's native channel count. - - result = ma_sound_init_ex(&soundConfig, &sound); - if (result != MA_SUCCESS) { - return result; - } - ``` - -In the example above, the sound is being initialized without a file nor a data source. This is -valid, in which case the sound acts as a node in the middle of the node graph. This means you can -connect other sounds to this sound and allow it to act like a sound group. Indeed, this is exactly -what a `ma_sound_group` is. - -When loading a sound, you specify a set of flags that control how the sound is loaded and what -features are enabled for that sound. When no flags are set, the sound will be fully loaded into -memory in exactly the same format as how it's stored on the file system. The resource manager will -allocate a block of memory and then load the file directly into it. When reading audio data, it -will be decoded dynamically on the fly. In order to save processing time on the audio thread, it -might be beneficial to pre-decode the sound. You can do this with the `MA_SOUND_FLAG_DECODE` flag: - - ```c - ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE, pGroup, NULL, &sound); - ``` - -By default, sounds will be loaded synchronously, meaning `ma_sound_init_*()` will not return until -the sound has been fully loaded. If this is prohibitive you can instead load sounds asynchronously -by specifying the `MA_SOUND_FLAG_ASYNC` flag: - - ```c - ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, NULL, &sound); - ``` - -This will result in `ma_sound_init_*()` returning quickly, but the sound won't yet have been fully -loaded. When you start the sound, it won't output anything until some sound is available. The sound -will start outputting audio before the sound has been fully decoded when the `MA_SOUND_FLAG_DECODE` -is specified. - -If you need to wait for an asynchronously loaded sound to be fully loaded, you can use a fence. A -fence in miniaudio is a simple synchronization mechanism which simply blocks until it's internal -counter hit's zero. You can specify a fence like so: - - ```c - ma_result result; - ma_fence fence; - ma_sound sounds[4]; - - result = ma_fence_init(&fence); - if (result != MA_SUCCESS) { - return result; - } - - // Load some sounds asynchronously. - for (int iSound = 0; iSound < 4; iSound += 1) { - ma_sound_init_from_file(&engine, mySoundFilesPaths[iSound], MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, &fence, &sounds[iSound]); - } - - // ... do some other stuff here in the mean time ... - - // Wait for all sounds to finish loading. - ma_fence_wait(&fence); - ``` - -If loading the entire sound into memory is prohibitive, you can also configure the engine to stream -the audio data: - - ```c - ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_STREAM, pGroup, NULL, &sound); - ``` - -When streaming sounds, 2 seconds worth of audio data is stored in memory. Although it should work -fine, it's inefficient to use streaming for short sounds. Streaming is useful for things like music -tracks in games. - -When loading a sound from a file path, the engine will reference count the file to prevent it from -being loaded if it's already in memory. When you uninitialize a sound, the reference count will be -decremented, and if it hits zero, the sound will be unloaded from memory. This reference counting -system is not used for streams. The engine will use a 64-bit hash of the file name when comparing -file paths which means there's a small chance you might encounter a name collision. If this is an -issue, you'll need to use a different name for one of the colliding file paths, or just not load -from files and instead load from a data source. - -You can use `ma_sound_init_copy()` to initialize a copy of another sound. Note, however, that this -only works for sounds that were initialized with `ma_sound_init_from_file()` and without the -`MA_SOUND_FLAG_STREAM` flag. - -When you initialize a sound, if you specify a sound group the sound will be attached to that group -automatically. If you set it to NULL, it will be automatically attached to the engine's endpoint. -If you would instead rather leave the sound unattached by default, you can can specify the -`MA_SOUND_FLAG_NO_DEFAULT_ATTACHMENT` flag. This is useful if you want to set up a complex node -graph. - -Sounds are not started by default. To start a sound, use `ma_sound_start()`. Stop a sound with -`ma_sound_stop()`. - -Sounds can have their volume controlled with `ma_sound_set_volume()` in the same way as the -engine's master volume. - -Sounds support stereo panning and pitching. Set the pan with `ma_sound_set_pan()`. Setting the pan -to 0 will result in an unpanned sound. Setting it to -1 will shift everything to the left, whereas -+1 will shift it to the right. The pitch can be controlled with `ma_sound_set_pitch()`. A larger -value will result in a higher pitch. The pitch must be greater than 0. - -The engine supports 3D spatialization of sounds. By default sounds will have spatialization -enabled, but if a sound does not need to be spatialized it's best to disable it. There are two ways -to disable spatialization of a sound: - - ```c - // Disable spatialization at initialization time via a flag: - ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_NO_SPATIALIZATION, NULL, NULL, &sound); - - // Dynamically disable or enable spatialization post-initialization: - ma_sound_set_spatialization_enabled(&sound, isSpatializationEnabled); - ``` - -By default sounds will be spatialized based on the closest listener. If a sound should always be -spatialized relative to a specific listener it can be pinned to one: - - ```c - ma_sound_set_pinned_listener_index(&sound, listenerIndex); - ``` - -Like listeners, sounds have a position. By default, the position of a sound is in absolute space, -but it can be changed to be relative to a listener: - - ```c - ma_sound_set_positioning(&sound, ma_positioning_relative); - ``` - -Note that relative positioning of a sound only makes sense if there is either only one listener, or -the sound is pinned to a specific listener. To set the position of a sound: - - ```c - ma_sound_set_position(&sound, posX, posY, posZ); - ``` - -The direction works the same way as a listener and represents the sound's forward direction: - - ```c - ma_sound_set_direction(&sound, forwardX, forwardY, forwardZ); - ``` - -Sound's also have a cone for controlling directional attenuation. This works exactly the same as -listeners: - - ```c - ma_sound_set_cone(&sound, innerAngleInRadians, outerAngleInRadians, outerGain); - ``` - -The velocity of a sound is used for doppler effect and can be set as such: - - ```c - ma_sound_set_velocity(&sound, velocityX, velocityY, velocityZ); - ``` - -The engine supports different attenuation models which can be configured on a per-sound basis. By -default the attenuation model is set to `ma_attenuation_model_inverse` which is the equivalent to -OpenAL's `AL_INVERSE_DISTANCE_CLAMPED`. Configure the attenuation model like so: - - ```c - ma_sound_set_attenuation_model(&sound, ma_attenuation_model_inverse); - ``` - -The supported attenuation models include the following: - - +----------------------------------+----------------------------------------------+ - | ma_attenuation_model_none | No distance attenuation. | - +----------------------------------+----------------------------------------------+ - | ma_attenuation_model_inverse | Equivalent to `AL_INVERSE_DISTANCE_CLAMPED`. | - +----------------------------------+----------------------------------------------+ - | ma_attenuation_model_linear | Linear attenuation. | - +----------------------------------+----------------------------------------------+ - | ma_attenuation_model_exponential | Exponential attenuation. | - +----------------------------------+----------------------------------------------+ - -To control how quickly a sound rolls off as it moves away from the listener, you need to configure -the rolloff: - - ```c - ma_sound_set_rolloff(&sound, rolloff); - ``` - -You can control the minimum and maximum gain to apply from spatialization: - - ```c - ma_sound_set_min_gain(&sound, minGain); - ma_sound_set_max_gain(&sound, maxGain); - ``` - -Likewise, in the calculation of attenuation, you can control the minimum and maximum distances for -the attenuation calculation. This is useful if you want to ensure sounds don't drop below a certain -volume after the listener moves further away and to have sounds play a maximum volume when the -listener is within a certain distance: - - ```c - ma_sound_set_min_distance(&sound, minDistance); - ma_sound_set_max_distance(&sound, maxDistance); - ``` - -The engine's spatialization system supports doppler effect. The doppler factor can be configure on -a per-sound basis like so: - - ```c - ma_sound_set_doppler_factor(&sound, dopplerFactor); - ``` - -You can fade sounds in and out with `ma_sound_set_fade_in_pcm_frames()` and -`ma_sound_set_fade_in_milliseconds()`. Set the volume to -1 to use the current volume as the -starting volume: - - ```c - // Fade in over 1 second. - ma_sound_set_fade_in_milliseconds(&sound, 0, 1, 1000); - - // ... sometime later ... - - // Fade out over 1 second, starting from the current volume. - ma_sound_set_fade_in_milliseconds(&sound, -1, 0, 1000); - ``` - -By default sounds will start immediately, but sometimes for timing and synchronization purposes it -can be useful to schedule a sound to start or stop: - - ```c - // Start the sound in 1 second from now. - ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 1)); - - // Stop the sound in 2 seconds from now. - ma_sound_set_stop_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2)); - ``` - -Note that scheduling a start time still requires an explicit call to `ma_sound_start()` before -anything will play. - -The time is specified in global time which is controlled by the engine. You can get the engine's -current time with `ma_engine_get_time_in_pcm_frames()`. The engine's global time is incremented -automatically as audio data is read, but it can be reset with `ma_engine_set_time_in_pcm_frames()` -in case it needs to be resynchronized for some reason. - -To determine whether or not a sound is currently playing, use `ma_sound_is_playing()`. This will -take the scheduled start and stop times into account. - -Whether or not a sound should loop can be controlled with `ma_sound_set_looping()`. Sounds will not -be looping by default. Use `ma_sound_is_looping()` to determine whether or not a sound is looping. - -Use `ma_sound_at_end()` to determine whether or not a sound is currently at the end. For a looping -sound this should never return true. Alternatively, you can configure a callback that will be fired -when the sound reaches the end. Note that the callback is fired from the audio thread which means -you cannot be uninitializing sound from the callback. To set the callback you can use -`ma_sound_set_end_callback()`. Alternatively, if you're using `ma_sound_init_ex()`, you can pass it -into the config like so: - - ```c - soundConfig.endCallback = my_end_callback; - soundConfig.pEndCallbackUserData = pMyEndCallbackUserData; - ``` - -The end callback is declared like so: - - ```c - void my_end_callback(void* pUserData, ma_sound* pSound) - { - ... - } - ``` - -Internally a sound wraps around a data source. Some APIs exist to control the underlying data -source, mainly for convenience: - - ```c - ma_sound_seek_to_pcm_frame(&sound, frameIndex); - ma_sound_get_data_format(&sound, &format, &channels, &sampleRate, pChannelMap, channelMapCapacity); - ma_sound_get_cursor_in_pcm_frames(&sound, &cursor); - ma_sound_get_length_in_pcm_frames(&sound, &length); - ``` - -Sound groups have the same API as sounds, only they are called `ma_sound_group`, and since they do -not have any notion of a data source, anything relating to a data source is unavailable. - -Internally, sound data is loaded via the `ma_decoder` API which means by default it only supports -file formats that have built-in support in miniaudio. You can extend this to support any kind of -file format through the use of custom decoders. To do this you'll need to use a self-managed -resource manager and configure it appropriately. See the "Resource Management" section below for -details on how to set this up. - - -6. Resource Management -====================== -Many programs will want to manage sound resources for things such as reference counting and -streaming. This is supported by miniaudio via the `ma_resource_manager` API. - -The resource manager is mainly responsible for the following: - - * Loading of sound files into memory with reference counting. - * Streaming of sound data. - -When loading a sound file, the resource manager will give you back a `ma_data_source` compatible -object called `ma_resource_manager_data_source`. This object can be passed into any -`ma_data_source` API which is how you can read and seek audio data. When loading a sound file, you -specify whether or not you want the sound to be fully loaded into memory (and optionally -pre-decoded) or streamed. When loading into memory, you can also specify whether or not you want -the data to be loaded asynchronously. - -The example below is how you can initialize a resource manager using it's default configuration: - - ```c - ma_resource_manager_config config; - ma_resource_manager resourceManager; - - config = ma_resource_manager_config_init(); - result = ma_resource_manager_init(&config, &resourceManager); - if (result != MA_SUCCESS) { - ma_device_uninit(&device); - printf("Failed to initialize the resource manager."); - return -1; - } - ``` - -You can configure the format, channels and sample rate of the decoded audio data. By default it -will use the file's native data format, but you can configure it to use a consistent format. This -is useful for offloading the cost of data conversion to load time rather than dynamically -converting at mixing time. To do this, you configure the decoded format, channels and sample rate -like the code below: - - ```c - config = ma_resource_manager_config_init(); - config.decodedFormat = device.playback.format; - config.decodedChannels = device.playback.channels; - config.decodedSampleRate = device.sampleRate; - ``` - -In the code above, the resource manager will be configured so that any decoded audio data will be -pre-converted at load time to the device's native data format. If instead you used defaults and -the data format of the file did not match the device's data format, you would need to convert the -data at mixing time which may be prohibitive in high-performance and large scale scenarios like -games. - -Internally the resource manager uses the `ma_decoder` API to load sounds. This means by default it -only supports decoders that are built into miniaudio. It's possible to support additional encoding -formats through the use of custom decoders. To do so, pass in your `ma_decoding_backend_vtable` -vtables into the resource manager config: - - ```c - ma_decoding_backend_vtable* pCustomBackendVTables[] = - { - &g_ma_decoding_backend_vtable_libvorbis, - &g_ma_decoding_backend_vtable_libopus - }; - - ... - - resourceManagerConfig.ppCustomDecodingBackendVTables = pCustomBackendVTables; - resourceManagerConfig.customDecodingBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); - resourceManagerConfig.pCustomDecodingBackendUserData = NULL; - ``` - -This system can allow you to support any kind of file format. See the "Decoding" section for -details on how to implement custom decoders. The miniaudio repository includes examples for Opus -via libopus and libopusfile and Vorbis via libvorbis and libvorbisfile. - -Asynchronicity is achieved via a job system. When an operation needs to be performed, such as the -decoding of a page, a job will be posted to a queue which will then be processed by a job thread. -By default there will be only one job thread running, but this can be configured, like so: - - ```c - config = ma_resource_manager_config_init(); - config.jobThreadCount = MY_JOB_THREAD_COUNT; - ``` - -By default job threads are managed internally by the resource manager, however you can also self -manage your job threads if, for example, you want to integrate the job processing into your -existing job infrastructure, or if you simply don't like the way the resource manager does it. To -do this, just set the job thread count to 0 and process jobs manually. To process jobs, you first -need to retrieve a job using `ma_resource_manager_next_job()` and then process it using -`ma_job_process()`: - - ```c - config = ma_resource_manager_config_init(); - config.jobThreadCount = 0; // Don't manage any job threads internally. - config.flags = MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING; // Optional. Makes `ma_resource_manager_next_job()` non-blocking. - - // ... Initialize your custom job threads ... - - void my_custom_job_thread(...) - { - for (;;) { - ma_job job; - ma_result result = ma_resource_manager_next_job(pMyResourceManager, &job); - if (result != MA_SUCCESS) { - if (result == MA_NO_DATA_AVAILABLE) { - // No jobs are available. Keep going. Will only get this if the resource manager was initialized - // with MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING. - continue; - } else if (result == MA_CANCELLED) { - // MA_JOB_TYPE_QUIT was posted. Exit. - break; - } else { - // Some other error occurred. - break; - } - } - - ma_job_process(&job); - } - } - ``` - -In the example above, the `MA_JOB_TYPE_QUIT` event is the used as the termination -indicator, but you can use whatever you would like to terminate the thread. The call to -`ma_resource_manager_next_job()` is blocking by default, but can be configured to be non-blocking -by initializing the resource manager with the `MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING` configuration -flag. Note that the `MA_JOB_TYPE_QUIT` will never be removed from the job queue. This -is to give every thread the opportunity to catch the event and terminate naturally. - -When loading a file, it's sometimes convenient to be able to customize how files are opened and -read instead of using standard `fopen()`, `fclose()`, etc. which is what miniaudio will use by -default. This can be done by setting `pVFS` member of the resource manager's config: - - ```c - // Initialize your custom VFS object. See documentation for VFS for information on how to do this. - my_custom_vfs vfs = my_custom_vfs_init(); - - config = ma_resource_manager_config_init(); - config.pVFS = &vfs; - ``` - -This is particularly useful in programs like games where you want to read straight from an archive -rather than the normal file system. If you do not specify a custom VFS, the resource manager will -use the operating system's normal file operations. - -To load a sound file and create a data source, call `ma_resource_manager_data_source_init()`. When -loading a sound you need to specify the file path and options for how the sounds should be loaded. -By default a sound will be loaded synchronously. The returned data source is owned by the caller -which means the caller is responsible for the allocation and freeing of the data source. Below is -an example for initializing a data source: - - ```c - ma_resource_manager_data_source dataSource; - ma_result result = ma_resource_manager_data_source_init(pResourceManager, pFilePath, flags, &dataSource); - if (result != MA_SUCCESS) { - // Error. - } - - // ... - - // A ma_resource_manager_data_source object is compatible with the `ma_data_source` API. To read data, just call - // the `ma_data_source_read_pcm_frames()` like you would with any normal data source. - result = ma_data_source_read_pcm_frames(&dataSource, pDecodedData, frameCount, &framesRead); - if (result != MA_SUCCESS) { - // Failed to read PCM frames. - } - - // ... - - ma_resource_manager_data_source_uninit(&dataSource); - ``` - -The `flags` parameter specifies how you want to perform loading of the sound file. It can be a -combination of the following flags: - - ``` - MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM - MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE - MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC - MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_WAIT_INIT - ``` - -When no flags are specified (set to 0), the sound will be fully loaded into memory, but not -decoded, meaning the raw file data will be stored in memory, and then dynamically decoded when -`ma_data_source_read_pcm_frames()` is called. To instead decode the audio data before storing it in -memory, use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` flag. By default, the sound file will -be loaded synchronously, meaning `ma_resource_manager_data_source_init()` will only return after -the entire file has been loaded. This is good for simplicity, but can be prohibitively slow. You -can instead load the sound asynchronously using the `MA_RESOURCE_MANAGER_DATA_SOURCE_ASYNC` flag. -This will result in `ma_resource_manager_data_source_init()` returning quickly, but no data will be -returned by `ma_data_source_read_pcm_frames()` until some data is available. When no data is -available because the asynchronous decoding hasn't caught up, `MA_BUSY` will be returned by -`ma_data_source_read_pcm_frames()`. - -For large sounds, it's often prohibitive to store the entire file in memory. To mitigate this, you -can instead stream audio data which you can do by specifying the -`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. When streaming, data will be decoded in 1 -second pages. When a new page needs to be decoded, a job will be posted to the job queue and then -subsequently processed in a job thread. - -For in-memory sounds, reference counting is used to ensure the data is loaded only once. This means -multiple calls to `ma_resource_manager_data_source_init()` with the same file path will result in -the file data only being loaded once. Each call to `ma_resource_manager_data_source_init()` must be -matched up with a call to `ma_resource_manager_data_source_uninit()`. Sometimes it can be useful -for a program to register self-managed raw audio data and associate it with a file path. Use the -`ma_resource_manager_register_*()` and `ma_resource_manager_unregister_*()` APIs to do this. -`ma_resource_manager_register_decoded_data()` is used to associate a pointer to raw, self-managed -decoded audio data in the specified data format with the specified name. Likewise, -`ma_resource_manager_register_encoded_data()` is used to associate a pointer to raw self-managed -encoded audio data (the raw file data) with the specified name. Note that these names need not be -actual file paths. When `ma_resource_manager_data_source_init()` is called (without the -`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag), the resource manager will look for these -explicitly registered data buffers and, if found, will use it as the backing data for the data -source. Note that the resource manager does *not* make a copy of this data so it is up to the -caller to ensure the pointer stays valid for it's lifetime. Use -`ma_resource_manager_unregister_data()` to unregister the self-managed data. You can also use -`ma_resource_manager_register_file()` and `ma_resource_manager_unregister_file()` to register and -unregister a file. It does not make sense to use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` -flag with a self-managed data pointer. - - -6.1. Asynchronous Loading and Synchronization ---------------------------------------------- -When loading asynchronously, it can be useful to poll whether or not loading has finished. Use -`ma_resource_manager_data_source_result()` to determine this. For in-memory sounds, this will -return `MA_SUCCESS` when the file has been *entirely* decoded. If the sound is still being decoded, -`MA_BUSY` will be returned. Otherwise, some other error code will be returned if the sound failed -to load. For streaming data sources, `MA_SUCCESS` will be returned when the first page has been -decoded and the sound is ready to be played. If the first page is still being decoded, `MA_BUSY` -will be returned. Otherwise, some other error code will be returned if the sound failed to load. - -In addition to polling, you can also use a simple synchronization object called a "fence" to wait -for asynchronously loaded sounds to finish. This is called `ma_fence`. The advantage to using a -fence is that it can be used to wait for a group of sounds to finish loading rather than waiting -for sounds on an individual basis. There are two stages to loading a sound: - - * Initialization of the internal decoder; and - * Completion of decoding of the file (the file is fully decoded) - -You can specify separate fences for each of the different stages. Waiting for the initialization -of the internal decoder is important for when you need to know the sample format, channels and -sample rate of the file. - -The example below shows how you could use a fence when loading a number of sounds: - - ```c - // This fence will be released when all sounds are finished loading entirely. - ma_fence fence; - ma_fence_init(&fence); - - // This will be passed into the initialization routine for each sound. - ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); - notifications.done.pFence = &fence; - - // Now load a bunch of sounds: - for (iSound = 0; iSound < soundCount; iSound += 1) { - ma_resource_manager_data_source_init(pResourceManager, pSoundFilePaths[iSound], flags, ¬ifications, &pSoundSources[iSound]); - } - - // ... DO SOMETHING ELSE WHILE SOUNDS ARE LOADING ... - - // Wait for loading of sounds to finish. - ma_fence_wait(&fence); - ``` - -In the example above we used a fence for waiting until the entire file has been fully decoded. If -you only need to wait for the initialization of the internal decoder to complete, you can use the -`init` member of the `ma_resource_manager_pipeline_notifications` object: - - ```c - notifications.init.pFence = &fence; - ``` - -If a fence is not appropriate for your situation, you can instead use a callback that is fired on -an individual sound basis. This is done in a very similar way to fences: - - ```c - typedef struct - { - ma_async_notification_callbacks cb; - void* pMyData; - } my_notification; - - void my_notification_callback(ma_async_notification* pNotification) - { - my_notification* pMyNotification = (my_notification*)pNotification; - - // Do something in response to the sound finishing loading. - } - - ... - - my_notification myCallback; - myCallback.cb.onSignal = my_notification_callback; - myCallback.pMyData = pMyData; - - ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); - notifications.done.pNotification = &myCallback; - - ma_resource_manager_data_source_init(pResourceManager, "my_sound.wav", flags, ¬ifications, &mySound); - ``` - -In the example above we just extend the `ma_async_notification_callbacks` object and pass an -instantiation into the `ma_resource_manager_pipeline_notifications` in the same way as we did with -the fence, only we set `pNotification` instead of `pFence`. You can set both of these at the same -time and they should both work as expected. If using the `pNotification` system, you need to ensure -your `ma_async_notification_callbacks` object stays valid. - - - -6.2. Resource Manager Implementation Details --------------------------------------------- -Resources are managed in two main ways: - - * By storing the entire sound inside an in-memory buffer (referred to as a data buffer) - * By streaming audio data on the fly (referred to as a data stream) - -A resource managed data source (`ma_resource_manager_data_source`) encapsulates a data buffer or -data stream, depending on whether or not the data source was initialized with the -`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. If so, it will make use of a -`ma_resource_manager_data_stream` object. Otherwise it will use a `ma_resource_manager_data_buffer` -object. Both of these objects are data sources which means they can be used with any -`ma_data_source_*()` API. - -Another major feature of the resource manager is the ability to asynchronously decode audio files. -This relieves the audio thread of time-consuming decoding which can negatively affect scalability -due to the audio thread needing to complete it's work extremely quickly to avoid glitching. -Asynchronous decoding is achieved through a job system. There is a central multi-producer, -multi-consumer, fixed-capacity job queue. When some asynchronous work needs to be done, a job is -posted to the queue which is then read by a job thread. The number of job threads can be -configured for improved scalability, and job threads can all run in parallel without needing to -worry about the order of execution (how this is achieved is explained below). - -When a sound is being loaded asynchronously, playback can begin before the sound has been fully -decoded. This enables the application to start playback of the sound quickly, while at the same -time allowing to resource manager to keep loading in the background. Since there may be less -threads than the number of sounds being loaded at a given time, a simple scheduling system is used -to keep decoding time balanced and fair. The resource manager solves this by splitting decoding -into chunks called pages. By default, each page is 1 second long. When a page has been decoded, a -new job will be posted to start decoding the next page. By dividing up decoding into pages, an -individual sound shouldn't ever delay every other sound from having their first page decoded. Of -course, when loading many sounds at the same time, there will always be an amount of time required -to process jobs in the queue so in heavy load situations there will still be some delay. To -determine if a data source is ready to have some frames read, use -`ma_resource_manager_data_source_get_available_frames()`. This will return the number of frames -available starting from the current position. - - -6.2.1. Job Queue ----------------- -The resource manager uses a job queue which is multi-producer, multi-consumer, and fixed-capacity. -This job queue is not currently lock-free, and instead uses a spinlock to achieve thread-safety. -Only a fixed number of jobs can be allocated and inserted into the queue which is done through a -lock-free data structure for allocating an index into a fixed sized array, with reference counting -for mitigation of the ABA problem. The reference count is 32-bit. - -For many types of jobs it's important that they execute in a specific order. In these cases, jobs -are executed serially. For the resource manager, serial execution of jobs is only required on a -per-object basis (per data buffer or per data stream). Each of these objects stores an execution -counter. When a job is posted it is associated with an execution counter. When the job is -processed, it checks if the execution counter of the job equals the execution counter of the -owning object and if so, processes the job. If the counters are not equal, the job will be posted -back onto the job queue for later processing. When the job finishes processing the execution order -of the main object is incremented. This system means the no matter how many job threads are -executing, decoding of an individual sound will always get processed serially. The advantage to -having multiple threads comes into play when loading multiple sounds at the same time. - -The resource manager's job queue is not 100% lock-free and will use a spinlock to achieve -thread-safety for a very small section of code. This is only relevant when the resource manager -uses more than one job thread. If only using a single job thread, which is the default, the -lock should never actually wait in practice. The amount of time spent locking should be quite -short, but it's something to be aware of for those who have pedantic lock-free requirements and -need to use more than one job thread. There are plans to remove this lock in a future version. - -In addition, posting a job will release a semaphore, which on Win32 is implemented with -`ReleaseSemaphore` and on POSIX platforms via a condition variable: - - ```c - pthread_mutex_lock(&pSemaphore->lock); - { - pSemaphore->value += 1; - pthread_cond_signal(&pSemaphore->cond); - } - pthread_mutex_unlock(&pSemaphore->lock); - ``` - -Again, this is relevant for those with strict lock-free requirements in the audio thread. To avoid -this, you can use non-blocking mode (via the `MA_JOB_QUEUE_FLAG_NON_BLOCKING` -flag) and implement your own job processing routine (see the "Resource Manager" section above for -details on how to do this). - - - -6.2.2. Data Buffers -------------------- -When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag is excluded at initialization time, the -resource manager will try to load the data into an in-memory data buffer. Before doing so, however, -it will first check if the specified file is already loaded. If so, it will increment a reference -counter and just use the already loaded data. This saves both time and memory. When the data buffer -is uninitialized, the reference counter will be decremented. If the counter hits zero, the file -will be unloaded. This is a detail to keep in mind because it could result in excessive loading and -unloading of a sound. For example, the following sequence will result in a file be loaded twice, -once after the other: - - ```c - ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer0); // Refcount = 1. Initial load. - ma_resource_manager_data_source_uninit(&myDataBuffer0); // Refcount = 0. Unloaded. - - ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer1); // Refcount = 1. Reloaded because previous uninit() unloaded it. - ma_resource_manager_data_source_uninit(&myDataBuffer1); // Refcount = 0. Unloaded. - ``` - -A binary search tree (BST) is used for storing data buffers as it has good balance between -efficiency and simplicity. The key of the BST is a 64-bit hash of the file path that was passed -into `ma_resource_manager_data_source_init()`. The advantage of using a hash is that it saves -memory over storing the entire path, has faster comparisons, and results in a mostly balanced BST -due to the random nature of the hash. The disadvantages are that file names are case-sensitive and -there's a small chance of name collisions. If case-sensitivity is an issue, you should normalize -your file names to upper- or lower-case before initializing your data sources. If name collisions -become an issue, you'll need to change the name of one of the colliding names or just not use the -resource manager. - -When a sound file has not already been loaded and the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` -flag is excluded, the file will be decoded synchronously by the calling thread. There are two -options for controlling how the audio is stored in the data buffer - encoded or decoded. When the -`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` option is excluded, the raw file data will be stored -in memory. Otherwise the sound will be decoded before storing it in memory. Synchronous loading is -a very simple and standard process of simply adding an item to the BST, allocating a block of -memory and then decoding (if `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` is specified). - -When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag is specified, loading of the data buffer -is done asynchronously. In this case, a job is posted to the queue to start loading and then the -function immediately returns, setting an internal result code to `MA_BUSY`. This result code is -returned when the program calls `ma_resource_manager_data_source_result()`. When decoding has fully -completed `MA_SUCCESS` will be returned. This can be used to know if loading has fully completed. - -When loading asynchronously, a single job is posted to the queue of the type -`MA_JOB_TYPE_RESOURCE_MANAGER_LOAD_DATA_BUFFER_NODE`. This involves making a copy of the file path and -associating it with job. When the job is processed by the job thread, it will first load the file -using the VFS associated with the resource manager. When using a custom VFS, it's important that it -be completely thread-safe because it will be used from one or more job threads at the same time. -Individual files should only ever be accessed by one thread at a time, however. After opening the -file via the VFS, the job will determine whether or not the file is being decoded. If not, it -simply allocates a block of memory and loads the raw file contents into it and returns. On the -other hand, when the file is being decoded, it will first allocate a decoder on the heap and -initialize it. Then it will check if the length of the file is known. If so it will allocate a -block of memory to store the decoded output and initialize it to silence. If the size is unknown, -it will allocate room for one page. After memory has been allocated, the first page will be -decoded. If the sound is shorter than a page, the result code will be set to `MA_SUCCESS` and the -completion event will be signalled and loading is now complete. If, however, there is more to -decode, a job with the code `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` is posted. This job -will decode the next page and perform the same process if it reaches the end. If there is more to -decode, the job will post another `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` job which will -keep on happening until the sound has been fully decoded. For sounds of an unknown length, each -page will be linked together as a linked list. Internally this is implemented via the -`ma_paged_audio_buffer` object. - - -6.2.3. Data Streams -------------------- -Data streams only ever store two pages worth of data for each instance. They are most useful for -large sounds like music tracks in games that would consume too much memory if fully decoded in -memory. After every frame from a page has been read, a job will be posted to load the next page -which is done from the VFS. - -For data streams, the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag will determine whether or -not initialization of the data source waits until the two pages have been decoded. When unset, -`ma_resource_manager_data_source_init()` will wait until the two pages have been loaded, otherwise -it will return immediately. - -When frames are read from a data stream using `ma_resource_manager_data_source_read_pcm_frames()`, -`MA_BUSY` will be returned if there are no frames available. If there are some frames available, -but less than the number requested, `MA_SUCCESS` will be returned, but the actual number of frames -read will be less than the number requested. Due to the asynchronous nature of data streams, -seeking is also asynchronous. If the data stream is in the middle of a seek, `MA_BUSY` will be -returned when trying to read frames. - -When `ma_resource_manager_data_source_read_pcm_frames()` results in a page getting fully consumed -a job is posted to load the next page. This will be posted from the same thread that called -`ma_resource_manager_data_source_read_pcm_frames()`. - -Data streams are uninitialized by posting a job to the queue, but the function won't return until -that job has been processed. The reason for this is that the caller owns the data stream object and -therefore miniaudio needs to ensure everything completes before handing back control to the caller. -Also, if the data stream is uninitialized while pages are in the middle of decoding, they must -complete before destroying any underlying object and the job system handles this cleanly. - -Note that when a new page needs to be loaded, a job will be posted to the resource manager's job -thread from the audio thread. You must keep in mind the details mentioned in the "Job Queue" -section above regarding locking when posting an event if you require a strictly lock-free audio -thread. - - - -7. Node Graph -============= -miniaudio's routing infrastructure follows a node graph paradigm. The idea is that you create a -node whose outputs are attached to inputs of another node, thereby creating a graph. There are -different types of nodes, with each node in the graph processing input data to produce output, -which is then fed through the chain. Each node in the graph can apply their own custom effects. At -the start of the graph will usually be one or more data source nodes which have no inputs and -instead pull their data from a data source. At the end of the graph is an endpoint which represents -the end of the chain and is where the final output is ultimately extracted from. - -Each node has a number of input buses and a number of output buses. An output bus from a node is -attached to an input bus of another. Multiple nodes can connect their output buses to another -node's input bus, in which case their outputs will be mixed before processing by the node. Below is -a diagram that illustrates a hypothetical node graph setup: - - ``` - >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Data flows left to right >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> - - +---------------+ +-----------------+ - | Data Source 1 =----+ +----------+ +----= Low Pass Filter =----+ - +---------------+ | | =----+ +-----------------+ | +----------+ - +----= Splitter | +----= ENDPOINT | - +---------------+ | | =----+ +-----------------+ | +----------+ - | Data Source 2 =----+ +----------+ +----= Echo / Delay =----+ - +---------------+ +-----------------+ - ``` - -In the above graph, it starts with two data sources whose outputs are attached to the input of a -splitter node. It's at this point that the two data sources are mixed. After mixing, the splitter -performs it's processing routine and produces two outputs which is simply a duplication of the -input stream. One output is attached to a low pass filter, whereas the other output is attached to -a echo/delay. The outputs of the the low pass filter and the echo are attached to the endpoint, and -since they're both connected to the same input bus, they'll be mixed. - -Each input bus must be configured to accept the same number of channels, but the number of channels -used by input buses can be different to the number of channels for output buses in which case -miniaudio will automatically convert the input data to the output channel count before processing. -The number of channels of an output bus of one node must match the channel count of the input bus -it's attached to. The channel counts cannot be changed after the node has been initialized. If you -attempt to attach an output bus to an input bus with a different channel count, attachment will -fail. - -To use a node graph, you first need to initialize a `ma_node_graph` object. This is essentially a -container around the entire graph. The `ma_node_graph` object is required for some thread-safety -issues which will be explained later. A `ma_node_graph` object is initialized using miniaudio's -standard config/init system: - - ```c - ma_node_graph_config nodeGraphConfig = ma_node_graph_config_init(myChannelCount); - - result = ma_node_graph_init(&nodeGraphConfig, NULL, &nodeGraph); // Second parameter is a pointer to allocation callbacks. - if (result != MA_SUCCESS) { - // Failed to initialize node graph. - } - ``` - -When you initialize the node graph, you're specifying the channel count of the endpoint. The -endpoint is a special node which has one input bus and one output bus, both of which have the -same channel count, which is specified in the config. Any nodes that connect directly to the -endpoint must be configured such that their output buses have the same channel count. When you read -audio data from the node graph, it'll have the channel count you specified in the config. To read -data from the graph: - - ```c - ma_uint32 framesRead; - result = ma_node_graph_read_pcm_frames(&nodeGraph, pFramesOut, frameCount, &framesRead); - if (result != MA_SUCCESS) { - // Failed to read data from the node graph. - } - ``` - -When you read audio data, miniaudio starts at the node graph's endpoint node which then pulls in -data from it's input attachments, which in turn recursively pull in data from their inputs, and so -on. At the start of the graph there will be some kind of data source node which will have zero -inputs and will instead read directly from a data source. The base nodes don't literally need to -read from a `ma_data_source` object, but they will always have some kind of underlying object that -sources some kind of audio. The `ma_data_source_node` node can be used to read from a -`ma_data_source`. Data is always in floating-point format and in the number of channels you -specified when the graph was initialized. The sample rate is defined by the underlying data sources. -It's up to you to ensure they use a consistent and appropriate sample rate. - -The `ma_node` API is designed to allow custom nodes to be implemented with relative ease, but -miniaudio includes a few stock nodes for common functionality. This is how you would initialize a -node which reads directly from a data source (`ma_data_source_node`) which is an example of one -of the stock nodes that comes with miniaudio: - - ```c - ma_data_source_node_config config = ma_data_source_node_config_init(pMyDataSource); - - ma_data_source_node dataSourceNode; - result = ma_data_source_node_init(&nodeGraph, &config, NULL, &dataSourceNode); - if (result != MA_SUCCESS) { - // Failed to create data source node. - } - ``` - -The data source node will use the output channel count to determine the channel count of the output -bus. There will be 1 output bus and 0 input buses (data will be drawn directly from the data -source). The data source must output to floating-point (`ma_format_f32`) or else an error will be -returned from `ma_data_source_node_init()`. - -By default the node will not be attached to the graph. To do so, use `ma_node_attach_output_bus()`: - - ```c - result = ma_node_attach_output_bus(&dataSourceNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); - if (result != MA_SUCCESS) { - // Failed to attach node. - } - ``` - -The code above connects the data source node directly to the endpoint. Since the data source node -has only a single output bus, the index will always be 0. Likewise, the endpoint only has a single -input bus which means the input bus index will also always be 0. - -To detach a specific output bus, use `ma_node_detach_output_bus()`. To detach all output buses, use -`ma_node_detach_all_output_buses()`. If you want to just move the output bus from one attachment to -another, you do not need to detach first. You can just call `ma_node_attach_output_bus()` and it'll -deal with it for you. - -Less frequently you may want to create a specialized node. This will be a node where you implement -your own processing callback to apply a custom effect of some kind. This is similar to initializing -one of the stock node types, only this time you need to specify a pointer to a vtable containing a -pointer to the processing function and the number of input and output buses. Example: - - ```c - static void my_custom_node_process_pcm_frames(ma_node* pNode, const float** ppFramesIn, ma_uint32* pFrameCountIn, float** ppFramesOut, ma_uint32* pFrameCountOut) - { - // Do some processing of ppFramesIn (one stream of audio data per input bus) - const float* pFramesIn_0 = ppFramesIn[0]; // Input bus @ index 0. - const float* pFramesIn_1 = ppFramesIn[1]; // Input bus @ index 1. - float* pFramesOut_0 = ppFramesOut[0]; // Output bus @ index 0. - - // Do some processing. On input, `pFrameCountIn` will be the number of input frames in each - // buffer in `ppFramesIn` and `pFrameCountOut` will be the capacity of each of the buffers - // in `ppFramesOut`. On output, `pFrameCountIn` should be set to the number of input frames - // your node consumed and `pFrameCountOut` should be set the number of output frames that - // were produced. - // - // You should process as many frames as you can. If your effect consumes input frames at the - // same rate as output frames (always the case, unless you're doing resampling), you need - // only look at `ppFramesOut` and process that exact number of frames. If you're doing - // resampling, you'll need to be sure to set both `pFrameCountIn` and `pFrameCountOut` - // properly. - } - - static ma_node_vtable my_custom_node_vtable = - { - my_custom_node_process_pcm_frames, // The function that will be called to process your custom node. This is where you'd implement your effect processing. - NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. - 2, // 2 input buses. - 1, // 1 output bus. - 0 // Default flags. - }; - - ... - - // Each bus needs to have a channel count specified. To do this you need to specify the channel - // counts in an array and then pass that into the node config. - ma_uint32 inputChannels[2]; // Equal in size to the number of input channels specified in the vtable. - ma_uint32 outputChannels[1]; // Equal in size to the number of output channels specified in the vtable. - - inputChannels[0] = channelsIn; - inputChannels[1] = channelsIn; - outputChannels[0] = channelsOut; - - ma_node_config nodeConfig = ma_node_config_init(); - nodeConfig.vtable = &my_custom_node_vtable; - nodeConfig.pInputChannels = inputChannels; - nodeConfig.pOutputChannels = outputChannels; - - ma_node_base node; - result = ma_node_init(&nodeGraph, &nodeConfig, NULL, &node); - if (result != MA_SUCCESS) { - // Failed to initialize node. - } - ``` - -When initializing a custom node, as in the code above, you'll normally just place your vtable in -static space. The number of input and output buses are specified as part of the vtable. If you need -a variable number of buses on a per-node bases, the vtable should have the relevant bus count set -to `MA_NODE_BUS_COUNT_UNKNOWN`. In this case, the bus count should be set in the node config: - - ```c - static ma_node_vtable my_custom_node_vtable = - { - my_custom_node_process_pcm_frames, // The function that will be called process your custom node. This is where you'd implement your effect processing. - NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. - MA_NODE_BUS_COUNT_UNKNOWN, // The number of input buses is determined on a per-node basis. - 1, // 1 output bus. - 0 // Default flags. - }; - - ... - - ma_node_config nodeConfig = ma_node_config_init(); - nodeConfig.vtable = &my_custom_node_vtable; - nodeConfig.inputBusCount = myBusCount; // <-- Since the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN, the input bus count should be set here. - nodeConfig.pInputChannels = inputChannels; // <-- Make sure there are nodeConfig.inputBusCount elements in this array. - nodeConfig.pOutputChannels = outputChannels; // <-- The vtable specifies 1 output bus, so there must be 1 element in this array. - ``` - -In the above example it's important to never set the `inputBusCount` and `outputBusCount` members -to anything other than their defaults if the vtable specifies an explicit count. They can only be -set if the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN in the relevant bus count. - -Most often you'll want to create a structure to encapsulate your node with some extra data. You -need to make sure the `ma_node_base` object is your first member of the structure: - - ```c - typedef struct - { - ma_node_base base; // <-- Make sure this is always the first member. - float someCustomData; - } my_custom_node; - ``` - -By doing this, your object will be compatible with all `ma_node` APIs and you can attach it to the -graph just like any other node. - -In the custom processing callback (`my_custom_node_process_pcm_frames()` in the example above), the -number of channels for each bus is what was specified by the config when the node was initialized -with `ma_node_init()`. In addition, all attachments to each of the input buses will have been -pre-mixed by miniaudio. The config allows you to specify different channel counts for each -individual input and output bus. It's up to the effect to handle it appropriate, and if it can't, -return an error in it's initialization routine. - -Custom nodes can be assigned some flags to describe their behaviour. These are set via the vtable -and include the following: - - +-----------------------------------------+---------------------------------------------------+ - | Flag Name | Description | - +-----------------------------------------+---------------------------------------------------+ - | MA_NODE_FLAG_PASSTHROUGH | Useful for nodes that do not do any kind of audio | - | | processing, but are instead used for tracking | - | | time, handling events, etc. Also used by the | - | | internal endpoint node. It reads directly from | - | | the input bus to the output bus. Nodes with this | - | | flag must have exactly 1 input bus and 1 output | - | | bus, and both buses must have the same channel | - | | counts. | - +-----------------------------------------+---------------------------------------------------+ - | MA_NODE_FLAG_CONTINUOUS_PROCESSING | Causes the processing callback to be called even | - | | when no data is available to be read from input | - | | attachments. When a node has at least one input | - | | bus, but there are no inputs attached or the | - | | inputs do not deliver any data, the node's | - | | processing callback will not get fired. This flag | - | | will make it so the callback is always fired | - | | regardless of whether or not any input data is | - | | received. This is useful for effects like | - | | echos where there will be a tail of audio data | - | | that still needs to be processed even when the | - | | original data sources have reached their ends. It | - | | may also be useful for nodes that must always | - | | have their processing callback fired when there | - | | are no inputs attached. | - +-----------------------------------------+---------------------------------------------------+ - | MA_NODE_FLAG_ALLOW_NULL_INPUT | Used in conjunction with | - | | `MA_NODE_FLAG_CONTINUOUS_PROCESSING`. When this | - | | is set, the `ppFramesIn` parameter of the | - | | processing callback will be set to NULL when | - | | there are no input frames are available. When | - | | this is unset, silence will be posted to the | - | | processing callback. | - +-----------------------------------------+---------------------------------------------------+ - | MA_NODE_FLAG_DIFFERENT_PROCESSING_RATES | Used to tell miniaudio that input and output | - | | frames are processed at different rates. You | - | | should set this for any nodes that perform | - | | resampling. | - +-----------------------------------------+---------------------------------------------------+ - | MA_NODE_FLAG_SILENT_OUTPUT | Used to tell miniaudio that a node produces only | - | | silent output. This is useful for nodes where you | - | | don't want the output to contribute to the final | - | | mix. An example might be if you want split your | - | | stream and have one branch be output to a file. | - | | When using this flag, you should avoid writing to | - | | the output buffer of the node's processing | - | | callback because miniaudio will ignore it anyway. | - +-----------------------------------------+---------------------------------------------------+ - - -If you need to make a copy of an audio stream for effect processing you can use a splitter node -called `ma_splitter_node`. This takes has 1 input bus and splits the stream into 2 output buses. -You can use it like this: - - ```c - ma_splitter_node_config splitterNodeConfig = ma_splitter_node_config_init(channels); - - ma_splitter_node splitterNode; - result = ma_splitter_node_init(&nodeGraph, &splitterNodeConfig, NULL, &splitterNode); - if (result != MA_SUCCESS) { - // Failed to create node. - } - - // Attach your output buses to two different input buses (can be on two different nodes). - ma_node_attach_output_bus(&splitterNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); // Attach directly to the endpoint. - ma_node_attach_output_bus(&splitterNode, 1, &myEffectNode, 0); // Attach to input bus 0 of some effect node. - ``` - -The volume of an output bus can be configured on a per-bus basis: - - ```c - ma_node_set_output_bus_volume(&splitterNode, 0, 0.5f); - ma_node_set_output_bus_volume(&splitterNode, 1, 0.5f); - ``` - -In the code above we're using the splitter node from before and changing the volume of each of the -copied streams. - -You can start and stop a node with the following: - - ```c - ma_node_set_state(&splitterNode, ma_node_state_started); // The default state. - ma_node_set_state(&splitterNode, ma_node_state_stopped); - ``` - -By default the node is in a started state, but since it won't be connected to anything won't -actually be invoked by the node graph until it's connected. When you stop a node, data will not be -read from any of it's input connections. You can use this property to stop a group of sounds -atomically. - -You can configure the initial state of a node in it's config: - - ```c - nodeConfig.initialState = ma_node_state_stopped; - ``` - -Note that for the stock specialized nodes, all of their configs will have a `nodeConfig` member -which is the config to use with the base node. This is where the initial state can be configured -for specialized nodes: - - ```c - dataSourceNodeConfig.nodeConfig.initialState = ma_node_state_stopped; - ``` - -When using a specialized node like `ma_data_source_node` or `ma_splitter_node`, be sure to not -modify the `vtable` member of the `nodeConfig` object. - - -7.1. Timing ------------ -The node graph supports starting and stopping nodes at scheduled times. This is especially useful -for data source nodes where you want to get the node set up, but only start playback at a specific -time. There are two clocks: local and global. - -A local clock is per-node, whereas the global clock is per graph. Scheduling starts and stops can -only be done based on the global clock because the local clock will not be running while the node -is stopped. The global clocks advances whenever `ma_node_graph_read_pcm_frames()` is called. On the -other hand, the local clock only advances when the node's processing callback is fired, and is -advanced based on the output frame count. - -To retrieve the global time, use `ma_node_graph_get_time()`. The global time can be set with -`ma_node_graph_set_time()` which might be useful if you want to do seeking on a global timeline. -Getting and setting the local time is similar. Use `ma_node_get_time()` to retrieve the local time, -and `ma_node_set_time()` to set the local time. The global and local times will be advanced by the -audio thread, so care should be taken to avoid data races. Ideally you should avoid calling these -outside of the node processing callbacks which are always run on the audio thread. - -There is basic support for scheduling the starting and stopping of nodes. You can only schedule one -start and one stop at a time. This is mainly intended for putting nodes into a started or stopped -state in a frame-exact manner. Without this mechanism, starting and stopping of a node is limited -to the resolution of a call to `ma_node_graph_read_pcm_frames()` which would typically be in blocks -of several milliseconds. The following APIs can be used for scheduling node states: - - ```c - ma_node_set_state_time() - ma_node_get_state_time() - ``` - -The time is absolute and must be based on the global clock. An example is below: - - ```c - ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1); // Delay starting to 1 second. - ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5); // Delay stopping to 5 seconds. - ``` - -An example for changing the state using a relative time. - - ```c - ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1 + ma_node_graph_get_time(&myNodeGraph)); - ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5 + ma_node_graph_get_time(&myNodeGraph)); - ``` - -Note that due to the nature of multi-threading the times may not be 100% exact. If this is an -issue, consider scheduling state changes from within a processing callback. An idea might be to -have some kind of passthrough trigger node that is used specifically for tracking time and handling -events. - - - -7.2. Thread Safety and Locking ------------------------------- -When processing audio, it's ideal not to have any kind of locking in the audio thread. Since it's -expected that `ma_node_graph_read_pcm_frames()` would be run on the audio thread, it does so -without the use of any locks. This section discusses the implementation used by miniaudio and goes -over some of the compromises employed by miniaudio to achieve this goal. Note that the current -implementation may not be ideal - feedback and critiques are most welcome. - -The node graph API is not *entirely* lock-free. Only `ma_node_graph_read_pcm_frames()` is expected -to be lock-free. Attachment, detachment and uninitialization of nodes use locks to simplify the -implementation, but are crafted in a way such that such locking is not required when reading audio -data from the graph. Locking in these areas are achieved by means of spinlocks. - -The main complication with keeping `ma_node_graph_read_pcm_frames()` lock-free stems from the fact -that a node can be uninitialized, and it's memory potentially freed, while in the middle of being -processed on the audio thread. There are times when the audio thread will be referencing a node, -which means the uninitialization process of a node needs to make sure it delays returning until the -audio thread is finished so that control is not handed back to the caller thereby giving them a -chance to free the node's memory. - -When the audio thread is processing a node, it does so by reading from each of the output buses of -the node. In order for a node to process data for one of it's output buses, it needs to read from -each of it's input buses, and so on an so forth. It follows that once all output buses of a node -are detached, the node as a whole will be disconnected and no further processing will occur unless -it's output buses are reattached, which won't be happening when the node is being uninitialized. -By having `ma_node_detach_output_bus()` wait until the audio thread is finished with it, we can -simplify a few things, at the expense of making `ma_node_detach_output_bus()` a bit slower. By -doing this, the implementation of `ma_node_uninit()` becomes trivial - just detach all output -nodes, followed by each of the attachments to each of it's input nodes, and then do any final clean -up. - -With the above design, the worst-case scenario is `ma_node_detach_output_bus()` taking as long as -it takes to process the output bus being detached. This will happen if it's called at just the -wrong moment where the audio thread has just iterated it and has just started processing. The -caller of `ma_node_detach_output_bus()` will stall until the audio thread is finished, which -includes the cost of recursively processing it's inputs. This is the biggest compromise made with -the approach taken by miniaudio for it's lock-free processing system. The cost of detaching nodes -earlier in the pipeline (data sources, for example) will be cheaper than the cost of detaching -higher level nodes, such as some kind of final post-processing endpoint. If you need to do mass -detachments, detach starting from the lowest level nodes and work your way towards the final -endpoint node (but don't try detaching the node graph's endpoint). If the audio thread is not -running, detachment will be fast and detachment in any order will be the same. The reason nodes -need to wait for their input attachments to complete is due to the potential for desyncs between -data sources. If the node was to terminate processing mid way through processing it's inputs, -there's a chance that some of the underlying data sources will have been read, but then others not. -That will then result in a potential desynchronization when detaching and reattaching higher-level -nodes. A possible solution to this is to have an option when detaching to terminate processing -before processing all input attachments which should be fairly simple. - -Another compromise, albeit less significant, is locking when attaching and detaching nodes. This -locking is achieved by means of a spinlock in order to reduce memory overhead. A lock is present -for each input bus and output bus. When an output bus is connected to an input bus, both the output -bus and input bus is locked. This locking is specifically for attaching and detaching across -different threads and does not affect `ma_node_graph_read_pcm_frames()` in any way. The locking and -unlocking is mostly self-explanatory, but a slightly less intuitive aspect comes into it when -considering that iterating over attachments must not break as a result of attaching or detaching a -node while iteration is occurring. - -Attaching and detaching are both quite simple. When an output bus of a node is attached to an input -bus of another node, it's added to a linked list. Basically, an input bus is a linked list, where -each item in the list is and output bus. We have some intentional (and convenient) restrictions on -what can done with the linked list in order to simplify the implementation. First of all, whenever -something needs to iterate over the list, it must do so in a forward direction. Backwards iteration -is not supported. Also, items can only be added to the start of the list. - -The linked list is a doubly-linked list where each item in the list (an output bus) holds a pointer -to the next item in the list, and another to the previous item. A pointer to the previous item is -only required for fast detachment of the node - it is never used in iteration. This is an -important property because it means from the perspective of iteration, attaching and detaching of -an item can be done with a single atomic assignment. This is exploited by both the attachment and -detachment process. When attaching the node, the first thing that is done is the setting of the -local "next" and "previous" pointers of the node. After that, the item is "attached" to the list -by simply performing an atomic exchange with the head pointer. After that, the node is "attached" -to the list from the perspective of iteration. Even though the "previous" pointer of the next item -hasn't yet been set, from the perspective of iteration it's been attached because iteration will -only be happening in a forward direction which means the "previous" pointer won't actually ever get -used. The same general process applies to detachment. See `ma_node_attach_output_bus()` and -`ma_node_detach_output_bus()` for the implementation of this mechanism. - - - -8. Decoding -=========== -The `ma_decoder` API is used for reading audio files. Decoders are completely decoupled from -devices and can be used independently. Built-in support is included for the following formats: - - +---------+ - | Format | - +---------+ - | WAV | - | MP3 | - | FLAC | - +---------+ - -You can disable the built-in decoders by specifying one or more of the following options before the -miniaudio implementation: - - ```c - #define MA_NO_WAV - #define MA_NO_MP3 - #define MA_NO_FLAC - ``` - -miniaudio supports the ability to plug in custom decoders. See the section below for details on how -to use custom decoders. - -A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with -`ma_decoder_init_memory()`, or from data delivered via callbacks with `ma_decoder_init()`. Here is -an example for loading a decoder from a file: - - ```c - ma_decoder decoder; - ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder); - if (result != MA_SUCCESS) { - return false; // An error occurred. - } - - ... - - ma_decoder_uninit(&decoder); - ``` - -When initializing a decoder, you can optionally pass in a pointer to a `ma_decoder_config` object -(the `NULL` argument in the example above) which allows you to configure the output format, channel -count, sample rate and channel map: - - ```c - ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000); - ``` - -When passing in `NULL` for decoder config in `ma_decoder_init*()`, the output format will be the -same as that defined by the decoding backend. - -Data is read from the decoder as PCM frames. This will output the number of PCM frames actually -read. If this is less than the requested number of PCM frames it means you've reached the end. The -return value will be `MA_AT_END` if no samples have been read and the end has been reached. - - ```c - ma_result result = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead, &framesRead); - if (framesRead < framesToRead) { - // Reached the end. - } - ``` - -You can also seek to a specific frame like so: - - ```c - ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame); - if (result != MA_SUCCESS) { - return false; // An error occurred. - } - ``` - -If you want to loop back to the start, you can simply seek back to the first PCM frame: - - ```c - ma_decoder_seek_to_pcm_frame(pDecoder, 0); - ``` - -When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding -backend. This can be unnecessarily inefficient if the type is already known. In this case you can -use `encodingFormat` variable in the device config to specify a specific encoding format you want -to decode: - - ```c - decoderConfig.encodingFormat = ma_encoding_format_wav; - ``` - -See the `ma_encoding_format` enum for possible encoding formats. - -The `ma_decoder_init_file()` API will try using the file extension to determine which decoding -backend to prefer. - - -8.1. Custom Decoders --------------------- -It's possible to implement a custom decoder and plug it into miniaudio. This is extremely useful -when you want to use the `ma_decoder` API, but need to support an encoding format that's not one of -the stock formats supported by miniaudio. This can be put to particularly good use when using the -`ma_engine` and/or `ma_resource_manager` APIs because they use `ma_decoder` internally. If, for -example, you wanted to support Opus, you can do so with a custom decoder (there if a reference -Opus decoder in the "extras" folder of the miniaudio repository which uses libopus + libopusfile). - -A custom decoder must implement a data source. A vtable called `ma_decoding_backend_vtable` needs -to be implemented which is then passed into the decoder config: - - ```c - ma_decoding_backend_vtable* pCustomBackendVTables[] = - { - &g_ma_decoding_backend_vtable_libvorbis, - &g_ma_decoding_backend_vtable_libopus - }; - - ... - - decoderConfig = ma_decoder_config_init_default(); - decoderConfig.pCustomBackendUserData = NULL; - decoderConfig.ppCustomBackendVTables = pCustomBackendVTables; - decoderConfig.customBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); - ``` - -The `ma_decoding_backend_vtable` vtable has the following functions: - - ``` - onInit - onInitFile - onInitFileW - onInitMemory - onUninit - ``` - -There are only two functions that must be implemented - `onInit` and `onUninit`. The other -functions can be implemented for a small optimization for loading from a file path or memory. If -these are not specified, miniaudio will deal with it for you via a generic implementation. - -When you initialize a custom data source (by implementing the `onInit` function in the vtable) you -will need to output a pointer to a `ma_data_source` which implements your custom decoder. See the -section about data sources for details on how to implement this. Alternatively, see the -"custom_decoders" example in the miniaudio repository. - -The `onInit` function takes a pointer to some callbacks for the purpose of reading raw audio data -from some arbitrary source. You'll use these functions to read from the raw data and perform the -decoding. When you call them, you will pass in the `pReadSeekTellUserData` pointer to the relevant -parameter. - -The `pConfig` parameter in `onInit` can be used to configure the backend if appropriate. It's only -used as a hint and can be ignored. However, if any of the properties are relevant to your decoder, -an optimal implementation will handle the relevant properties appropriately. - -If memory allocation is required, it should be done so via the specified allocation callbacks if -possible (the `pAllocationCallbacks` parameter). - -If an error occurs when initializing the decoder, you should leave `ppBackend` unset, or set to -NULL, and make sure everything is cleaned up appropriately and an appropriate result code returned. -When multiple custom backends are specified, miniaudio will cycle through the vtables in the order -they're listed in the array that's passed into the decoder config so it's important that your -initialization routine is clean. - -When a decoder is uninitialized, the `onUninit` callback will be fired which will give you an -opportunity to clean up and internal data. - - - -9. Encoding -=========== -The `ma_encoding` API is used for writing audio files. The only supported output format is WAV. -This can be disabled by specifying the following option before the implementation of miniaudio: - - ```c - #define MA_NO_WAV - ``` - -An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data -delivered via callbacks with `ma_encoder_init()`. Below is an example for initializing an encoder -to output to a file. - - ```c - ma_encoder_config config = ma_encoder_config_init(ma_encoding_format_wav, FORMAT, CHANNELS, SAMPLE_RATE); - ma_encoder encoder; - ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder); - if (result != MA_SUCCESS) { - // Error - } - - ... - - ma_encoder_uninit(&encoder); - ``` - -When initializing an encoder you must specify a config which is initialized with -`ma_encoder_config_init()`. Here you must specify the file type, the output sample format, output -channel count and output sample rate. The following file types are supported: - - +------------------------+-------------+ - | Enum | Description | - +------------------------+-------------+ - | ma_encoding_format_wav | WAV | - +------------------------+-------------+ - -If the format, channel count or sample rate is not supported by the output file type an error will -be returned. The encoder will not perform data conversion so you will need to convert it before -outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the -example below: - - ```c - ma_uint64 framesWritten; - result = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite, &framesWritten); - if (result != MA_SUCCESS) { - ... handle error ... - } - ``` - -The `framesWritten` variable will contain the number of PCM frames that were actually written. This -is optionally and you can pass in `NULL` if you need this. - -Encoders must be uninitialized with `ma_encoder_uninit()`. - - - -10. Data Conversion -=================== -A data conversion API is included with miniaudio which supports the majority of data conversion -requirements. This supports conversion between sample formats, channel counts (with channel -mapping) and sample rates. - - -10.1. Sample Format Conversion ------------------------------- -Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and -`ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()` to convert between two specific -formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use -`ma_convert_pcm_frames_format()` to convert PCM frames where you want to specify the frame count -and channel count as a variable instead of the total sample count. - - -10.1.1. Dithering ------------------ -Dithering can be set using the ditherMode parameter. - -The different dithering modes include the following, in order of efficiency: - - +-----------+--------------------------+ - | Type | Enum Token | - +-----------+--------------------------+ - | None | ma_dither_mode_none | - | Rectangle | ma_dither_mode_rectangle | - | Triangle | ma_dither_mode_triangle | - +-----------+--------------------------+ - -Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be -ignored for conversions where dithering is not needed. Dithering is available for the following -conversions: - - ``` - s16 -> u8 - s24 -> u8 - s32 -> u8 - f32 -> u8 - s24 -> s16 - s32 -> s16 - f32 -> s16 - ``` - -Note that it is not an error to pass something other than ma_dither_mode_none for conversions where -dither is not used. It will just be ignored. - - - -10.2. Channel Conversion ------------------------- -Channel conversion is used for channel rearrangement and conversion from one channel count to -another. The `ma_channel_converter` API is used for channel conversion. Below is an example of -initializing a simple channel converter which converts from mono to stereo. - - ```c - ma_channel_converter_config config = ma_channel_converter_config_init( - ma_format, // Sample format - 1, // Input channels - NULL, // Input channel map - 2, // Output channels - NULL, // Output channel map - ma_channel_mix_mode_default); // The mixing algorithm to use when combining channels. - - result = ma_channel_converter_init(&config, NULL, &converter); - if (result != MA_SUCCESS) { - // Error. - } - ``` - -To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so: - - ```c - ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount); - if (result != MA_SUCCESS) { - // Error. - } - ``` - -It is up to the caller to ensure the output buffer is large enough to accommodate the new PCM -frames. - -Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported. - - -10.2.1. Channel Mapping ------------------------ -In addition to converting from one channel count to another, like the example above, the channel -converter can also be used to rearrange channels. When initializing the channel converter, you can -optionally pass in channel maps for both the input and output frames. If the channel counts are the -same, and each channel map contains the same channel positions with the exception that they're in -a different order, a simple shuffling of the channels will be performed. If, however, there is not -a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed -based on a mixing mode which is specified when initializing the `ma_channel_converter_config` -object. - -When converting from mono to multi-channel, the mono channel is simply copied to each output -channel. When going the other way around, the audio of each output channel is simply averaged and -copied to the mono channel. - -In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess -channels and silence extra channels. For example, converting from 4 to 2 channels, the 3rd and 4th -channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and -4th channels. - -The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a -simple distribution between input and output. Imagine sitting in the middle of a room, with -speakers on the walls representing channel positions. The `MA_CHANNEL_FRONT_LEFT` position can be -thought of as being in the corner of the front and left walls. - -Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined -weights. Custom weights can be passed in as the last parameter of -`ma_channel_converter_config_init()`. - -Predefined channel maps can be retrieved with `ma_channel_map_init_standard()`. This takes a -`ma_standard_channel_map` enum as it's first parameter, which can be one of the following: - - +-----------------------------------+-----------------------------------------------------------+ - | Name | Description | - +-----------------------------------+-----------------------------------------------------------+ - | ma_standard_channel_map_default | Default channel map used by miniaudio. See below. | - | ma_standard_channel_map_microsoft | Channel map used by Microsoft's bitfield channel maps. | - | ma_standard_channel_map_alsa | Default ALSA channel map. | - | ma_standard_channel_map_rfc3551 | RFC 3551.

Resampling ----------------- -Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something -like the following: - - ```c - ma_resampler_config config = ma_resampler_config_init( - ma_format_s16, - channels, - sampleRateIn, - sampleRateOut, - ma_resample_algorithm_linear); - - ma_resampler resampler; - ma_result result = ma_resampler_init(&config, &resampler); - if (result != MA_SUCCESS) { - // An error occurred... - } - ``` - -Do the following to uninitialize the resampler: - - ```c - ma_resampler_uninit(&resampler); - ``` - -The following example shows how data can be processed - - ```c - ma_uint64 frameCountIn = 1000; - ma_uint64 frameCountOut = 2000; - ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); - if (result != MA_SUCCESS) { - // An error occurred... - } - - // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the - // number of output frames written. - ``` - -To initialize the resampler you first need to set up a config (`ma_resampler_config`) with -`ma_resampler_config_init()`. You need to specify the sample format you want to use, the number of -channels, the input and output sample rate, and the algorithm. - -The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format -you will need to perform pre- and post-conversions yourself where necessary. Note that the format -is the same for both input and output. The format cannot be changed after initialization. - -The resampler supports multiple channels and is always interleaved (both input and output). The -channel count cannot be changed after initialization. - -The sample rates can be anything other than zero, and are always specified in hertz. They should be -set to something like 44100, etc. The sample rate is the only configuration property that can be -changed after initialization. - -The miniaudio resampler has built-in support for the following algorithms: - - +-----------+------------------------------+ - | Algorithm | Enum Token | - +-----------+------------------------------+ - | Linear | ma_resample_algorithm_linear | - | Custom | ma_resample_algorithm_custom | - +-----------+------------------------------+ - -The algorithm cannot be changed after initialization. - -Processing always happens on a per PCM frame basis and always assumes interleaved input and output. -De-interleaved processing is not supported. To process frames, use -`ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you -can fit in the output buffer and the number of input frames contained in the input buffer. On -output these variables contain the number of output frames that were written to the output buffer -and the number of input frames that were consumed in the process. You can pass in NULL for the -input buffer in which case it will be treated as an infinitely large buffer of zeros. The output -buffer can also be NULL, in which case the processing will be treated as seek. - -The sample rate can be changed dynamically on the fly. You can change this with explicit sample -rates with `ma_resampler_set_rate()` and also with a decimal ratio with -`ma_resampler_set_rate_ratio()`. The ratio is in/out. - -Sometimes it's useful to know exactly how many input frames will be required to output a specific -number of frames. You can calculate this with `ma_resampler_get_required_input_frame_count()`. -Likewise, it's sometimes useful to know exactly how many frames would be output given a certain -number of input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`. - -Due to the nature of how resampling works, the resampler introduces some latency. This can be -retrieved in terms of both the input rate and the output rate with -`ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`. - - -10.3.1. Resampling Algorithms ------------------------------ -The choice of resampling algorithm depends on your situation and requirements. - - -10.3.1.1. Linear Resampling ---------------------------- -The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, -some control over the quality of the linear resampler which may make it a suitable option depending -on your requirements. - -The linear resampler performs low-pass filtering before or after downsampling or upsampling, -depending on the sample rates you're converting between. When decreasing the sample rate, the -low-pass filter will be applied before downsampling. When increasing the rate it will be performed -after upsampling. By default a fourth order low-pass filter will be applied. This can be configured -via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering. - -The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of -the input and output sample rates (Nyquist Frequency). - -The API for the linear resampler is the same as the main resampler API, only it's called -`ma_linear_resampler`. - - -10.3.2. Custom Resamplers -------------------------- -You can implement a custom resampler by using the `ma_resample_algorithm_custom` resampling -algorithm and setting a vtable in the resampler config: - - ```c - ma_resampler_config config = ma_resampler_config_init(..., ma_resample_algorithm_custom); - config.pBackendVTable = &g_customResamplerVTable; - ``` - -Custom resamplers are useful if the stock algorithms are not appropriate for your use case. You -need to implement the required functions in `ma_resampling_backend_vtable`. Note that not all -functions in the vtable need to be implemented, but if it's possible to implement, they should be. - -You can use the `ma_linear_resampler` object for an example on how to implement the vtable. The -`onGetHeapSize` callback is used to calculate the size of any internal heap allocation the custom -resampler will need to make given the supplied config. When you initialize the resampler via the -`onInit` callback, you'll be given a pointer to a heap allocation which is where you should store -the heap allocated data. You should not free this data in `onUninit` because miniaudio will manage -it for you. - -The `onProcess` callback is where the actual resampling takes place. On input, `pFrameCountIn` -points to a variable containing the number of frames in the `pFramesIn` buffer and -`pFrameCountOut` points to a variable containing the capacity in frames of the `pFramesOut` buffer. -On output, `pFrameCountIn` should be set to the number of input frames that were fully consumed, -whereas `pFrameCountOut` should be set to the number of frames that were written to `pFramesOut`. - -The `onSetRate` callback is optional and is used for dynamically changing the sample rate. If -dynamic rate changes are not supported, you can set this callback to NULL. - -The `onGetInputLatency` and `onGetOutputLatency` functions are used for retrieving the latency in -input and output rates respectively. These can be NULL in which case latency calculations will be -assumed to be NULL. - -The `onGetRequiredInputFrameCount` callback is used to give miniaudio a hint as to how many input -frames are required to be available to produce the given number of output frames. Likewise, the -`onGetExpectedOutputFrameCount` callback is used to determine how many output frames will be -produced given the specified number of input frames. miniaudio will use these as a hint, but they -are optional and can be set to NULL if you're unable to implement them. - - - -10.4. General Data Conversion ------------------------------ -The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and -resampling into one operation. This is what miniaudio uses internally to convert between the format -requested when the device was initialized and the format of the backend's native device. The API -for general data conversion is very similar to the resampling API. Create a `ma_data_converter` -object like this: - - ```c - ma_data_converter_config config = ma_data_converter_config_init( - inputFormat, - outputFormat, - inputChannels, - outputChannels, - inputSampleRate, - outputSampleRate - ); - - ma_data_converter converter; - ma_result result = ma_data_converter_init(&config, NULL, &converter); - if (result != MA_SUCCESS) { - // An error occurred... - } - ``` - -In the example above we use `ma_data_converter_config_init()` to initialize the config, however -there's many more properties that can be configured, such as channel maps and resampling quality. -Something like the following may be more suitable depending on your requirements: - - ```c - ma_data_converter_config config = ma_data_converter_config_init_default(); - config.formatIn = inputFormat; - config.formatOut = outputFormat; - config.channelsIn = inputChannels; - config.channelsOut = outputChannels; - config.sampleRateIn = inputSampleRate; - config.sampleRateOut = outputSampleRate; - ma_channel_map_init_standard(ma_standard_channel_map_flac, config.channelMapIn, sizeof(config.channelMapIn)/sizeof(config.channelMapIn[0]), config.channelCountIn); - config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER; - ``` - -Do the following to uninitialize the data converter: - - ```c - ma_data_converter_uninit(&converter, NULL); - ``` - -The following example shows how data can be processed - - ```c - ma_uint64 frameCountIn = 1000; - ma_uint64 frameCountOut = 2000; - ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); - if (result != MA_SUCCESS) { - // An error occurred... - } - - // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number - // of output frames written. - ``` - -The data converter supports multiple channels and is always interleaved (both input and output). -The channel count cannot be changed after initialization. - -Sample rates can be anything other than zero, and are always specified in hertz. They should be set -to something like 44100, etc. The sample rate is the only configuration property that can be -changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of -`ma_data_converter_config` is set to `MA_TRUE`. To change the sample rate, use -`ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. -The resampling algorithm cannot be changed after initialization. - -Processing always happens on a per PCM frame basis and always assumes interleaved input and output. -De-interleaved processing is not supported. To process frames, use -`ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames -you can fit in the output buffer and the number of input frames contained in the input buffer. On -output these variables contain the number of output frames that were written to the output buffer -and the number of input frames that were consumed in the process. You can pass in NULL for the -input buffer in which case it will be treated as an infinitely large -buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated -as seek. - -Sometimes it's useful to know exactly how many input frames will be required to output a specific -number of frames. You can calculate this with `ma_data_converter_get_required_input_frame_count()`. -Likewise, it's sometimes useful to know exactly how many frames would be output given a certain -number of input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`. - -Due to the nature of how resampling works, the data converter introduces some latency if resampling -is required. This can be retrieved in terms of both the input rate and the output rate with -`ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`. - - - -11. Filtering -============= - -11.1. Biquad Filtering ----------------------- -Biquad filtering is achieved with the `ma_biquad` API. Example: - - ```c - ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2); - ma_result result = ma_biquad_init(&config, &biquad); - if (result != MA_SUCCESS) { - // Error. - } - - ... - - ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount); - ``` - -Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, -b1 and b2, and the denominator coefficients are a0, a1 and a2. The a0 coefficient is required and -coefficients must not be pre-normalized. - -Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format -you need to convert it yourself beforehand. When using `ma_format_s16` the biquad filter will use -fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used. - -Input and output frames are always interleaved. - -Filtering can be applied in-place by passing in the same pointer for both the input and output -buffers, like so: - - ```c - ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount); - ``` - -If you need to change the values of the coefficients, but maintain the values in the registers you -can do so with `ma_biquad_reinit()`. This is useful if you need to change the properties of the -filter while keeping the values of registers valid to avoid glitching. Do not use -`ma_biquad_init()` for this as it will do a full initialization which involves clearing the -registers to 0. Note that changing the format or channel count after initialization is invalid and -will result in an error. - - -11.2. Low-Pass Filtering ------------------------- -Low-pass filtering is achieved with the following APIs: - - +---------+------------------------------------------+ - | API | Description | - +---------+------------------------------------------+ - | ma_lpf1 | First order low-pass filter | - | ma_lpf2 | Second order low-pass filter | - | ma_lpf | High order low-pass filter (Butterworth) | - +---------+------------------------------------------+ - -Low-pass filter example: - - ```c - ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order); - ma_result result = ma_lpf_init(&config, &lpf); - if (result != MA_SUCCESS) { - // Error. - } - - ... - - ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount); - ``` - -Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format -you need to convert it yourself beforehand. Input and output frames are always interleaved. - -Filtering can be applied in-place by passing in the same pointer for both the input and output -buffers, like so: - - ```c - ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount); - ``` - -The maximum filter order is limited to `MA_MAX_FILTER_ORDER` which is set to 8. If you need more, -you can chain first and second order filters together. - - ```c - for (iFilter = 0; iFilter < filterCount; iFilter += 1) { - ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount); - } - ``` - -If you need to change the configuration of the filter, but need to maintain the state of internal -registers you can do so with `ma_lpf_reinit()`. This may be useful if you need to change the sample -rate and/or cutoff frequency dynamically while maintaining smooth transitions. Note that changing the -format or channel count after initialization is invalid and will result in an error. - -The `ma_lpf` object supports a configurable order, but if you only need a first order filter you -may want to consider using `ma_lpf1`. Likewise, if you only need a second order filter you can use -`ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient. - -If an even filter order is specified, a series of second order filters will be processed in a -chain. If an odd filter order is specified, a first order filter will be applied, followed by a -series of second order filters in a chain. - - -11.3. High-Pass Filtering -------------------------- -High-pass filtering is achieved with the following APIs: - - +---------+-------------------------------------------+ - | API | Description | - +---------+-------------------------------------------+ - | ma_hpf1 | First order high-pass filter | - | ma_hpf2 | Second order high-pass filter | - | ma_hpf | High order high-pass filter (Butterworth) | - +---------+-------------------------------------------+ - -High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, -`ma_hpf2` and `ma_hpf`. See example code for low-pass filters for example usage. - - -11.4. Band-Pass Filtering -------------------------- -Band-pass filtering is achieved with the following APIs: - - +---------+-------------------------------+ - | API | Description | - +---------+-------------------------------+ - | ma_bpf2 | Second order band-pass filter | - | ma_bpf | High order band-pass filter | - +---------+-------------------------------+ - -Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and -`ma_hpf`. See example code for low-pass filters for example usage. Note that the order for -band-pass filters must be an even number which means there is no first order band-pass filter, -unlike low-pass and high-pass filters. - - -11.5. Notch Filtering ---------------------- -Notch filtering is achieved with the following APIs: - - +-----------+------------------------------------------+ - | API | Description | - +-----------+------------------------------------------+ - | ma_notch2 | Second order notching filter | - +-----------+------------------------------------------+ - - -11.6. Peaking EQ Filtering -------------------------- -Peaking filtering is achieved with the following APIs: - - +----------+------------------------------------------+ - | API | Description | - +----------+------------------------------------------+ - | ma_peak2 | Second order peaking filter | - +----------+------------------------------------------+ - - -11.7. Low Shelf Filtering -------------------------- -Low shelf filtering is achieved with the following APIs: - - +-------------+------------------------------------------+ - | API | Description | - +-------------+------------------------------------------+ - | ma_loshelf2 | Second order low shelf filter | - +-------------+------------------------------------------+ - -Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to -just turn them down rather than eliminate them entirely. - - -11.8. High Shelf Filtering --------------------------- -High shelf filtering is achieved with the following APIs: - - +-------------+------------------------------------------+ - | API | Description | - +-------------+------------------------------------------+ - | ma_hishelf2 | Second order high shelf filter | - +-------------+------------------------------------------+ - -The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` -instead of `ma_loshelf`. Where a low shelf filter is used to adjust the volume of low frequencies, -the high shelf filter does the same thing for high frequencies. - - - - -12. Waveform and Noise Generation -================================= - -12.1. Waveforms ---------------- -miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved -with the `ma_waveform` API. Example: - - ```c - ma_waveform_config config = ma_waveform_config_init( - FORMAT, - CHANNELS, - SAMPLE_RATE, - ma_waveform_type_sine, - amplitude, - frequency); - - ma_waveform waveform; - ma_result result = ma_waveform_init(&config, &waveform); - if (result != MA_SUCCESS) { - // Error. - } - - ... - - ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount); - ``` - -The amplitude, frequency, type, and sample rate can be changed dynamically with -`ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()`, `ma_waveform_set_type()`, and -`ma_waveform_set_sample_rate()` respectively. - -You can invert the waveform by setting the amplitude to a negative value. You can use this to -control whether or not a sawtooth has a positive or negative ramp, for example. - -Below are the supported waveform types: - - +---------------------------+ - | Enum Name | - +---------------------------+ - | ma_waveform_type_sine | - | ma_waveform_type_square | - | ma_waveform_type_triangle | - | ma_waveform_type_sawtooth | - +---------------------------+ - - - -12.2. Noise ------------ -miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example: - - ```c - ma_noise_config config = ma_noise_config_init( - FORMAT, - CHANNELS, - ma_noise_type_white, - SEED, - amplitude); - - ma_noise noise; - ma_result result = ma_noise_init(&config, &noise); - if (result != MA_SUCCESS) { - // Error. - } - - ... - - ma_noise_read_pcm_frames(&noise, pOutput, frameCount); - ``` - -The noise API uses simple LCG random number generation. It supports a custom seed which is useful -for things like automated testing requiring reproducibility. Setting the seed to zero will default -to `MA_DEFAULT_LCG_SEED`. - -The amplitude and seed can be changed dynamically with `ma_noise_set_amplitude()` and -`ma_noise_set_seed()` respectively. - -By default, the noise API will use different values for different channels. So, for example, the -left side in a stereo stream will be different to the right side. To instead have each channel use -the same random value, set the `duplicateChannels` member of the noise config to true, like so: - - ```c - config.duplicateChannels = MA_TRUE; - ``` - -Below are the supported noise types. - - +------------------------+ - | Enum Name | - +------------------------+ - | ma_noise_type_white | - | ma_noise_type_pink | - | ma_noise_type_brownian | - +------------------------+ - - - -13. Audio Buffers -================= -miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can -read from memory that's managed by the application, but can also handle the memory management for -you internally. Memory management is flexible and should support most use cases. - -Audio buffers are initialized using the standard configuration system used everywhere in miniaudio: - - ```c - ma_audio_buffer_config config = ma_audio_buffer_config_init( - format, - channels, - sizeInFrames, - pExistingData, - &allocationCallbacks); - - ma_audio_buffer buffer; - result = ma_audio_buffer_init(&config, &buffer); - if (result != MA_SUCCESS) { - // Error. - } - - ... - - ma_audio_buffer_uninit(&buffer); - ``` - -In the example above, the memory pointed to by `pExistingData` will *not* be copied and is how an -application can do self-managed memory allocation. If you would rather make a copy of the data, use -`ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`. - -Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure and the -raw audio data in a contiguous block of memory. That is, the raw audio data will be located -immediately after the `ma_audio_buffer` structure. To do this, use -`ma_audio_buffer_alloc_and_init()`: - - ```c - ma_audio_buffer_config config = ma_audio_buffer_config_init( - format, - channels, - sizeInFrames, - pExistingData, - &allocationCallbacks); - - ma_audio_buffer* pBuffer - result = ma_audio_buffer_alloc_and_init(&config, &pBuffer); - if (result != MA_SUCCESS) { - // Error - } - - ... - - ma_audio_buffer_uninit_and_free(&buffer); - ``` - -If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it -with `ma_audio_buffer_uninit_and_free()`. In the example above, the memory pointed to by -`pExistingData` will be copied into the buffer, which is contrary to the behavior of -`ma_audio_buffer_init()`. - -An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the -cursor moves forward. The last parameter (`loop`) can be used to determine if the buffer should -loop. The return value is the number of frames actually read. If this is less than the number of -frames requested it means the end has been reached. This should never happen if the `loop` -parameter is set to true. If you want to manually loop back to the start, you can do so with with -`ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an -audio buffer. - - ```c - ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping); - if (framesRead < desiredFrameCount) { - // If not looping, this means the end has been reached. This should never happen in looping mode with valid input. - } - ``` - -Sometimes you may want to avoid the cost of data movement between the internal buffer and the -output buffer. Instead you can use memory mapping to retrieve a pointer to a segment of data: - - ```c - void* pMappedFrames; - ma_uint64 frameCount = frameCountToTryMapping; - ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount); - if (result == MA_SUCCESS) { - // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be - // less due to the end of the buffer being reached. - ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels); - - // You must unmap the buffer. - ma_audio_buffer_unmap(pAudioBuffer, frameCount); - } - ``` - -When you use memory mapping, the read cursor is increment by the frame count passed in to -`ma_audio_buffer_unmap()`. If you decide not to process every frame you can pass in a value smaller -than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is -that it does not handle looping for you. You can determine if the buffer is at the end for the -purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of -`ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` -as an error when returned by `ma_audio_buffer_unmap()`. - - - -14. Ring Buffers -================ -miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via -the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates on bytes, whereas the `ma_pcm_rb` -operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around -`ma_rb`. - -Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved -streams. The caller can also allocate their own backing memory for the ring buffer to use -internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for -you. - -The examples below use the PCM frame variant of the ring buffer since that's most likely the one -you will want to use. To initialize a ring buffer, do something like the following: - - ```c - ma_pcm_rb rb; - ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb); - if (result != MA_SUCCESS) { - // Error - } - ``` - -The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because -it's the PCM variant of the ring buffer API. For the regular ring buffer that operates on bytes you -would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes -instead of frames. The fourth parameter is an optional pre-allocated buffer and the fifth parameter -is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation routines. -Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used. - -Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is -offset from each other based on the stride. To manage your sub-buffers you can use -`ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and -`ma_pcm_rb_get_subbuffer_ptr()`. - -Use `ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section -of the ring buffer. You specify the number of frames you need, and on output it will set to what -was actually acquired. If the read or write pointer is positioned such that the number of frames -requested will require a loop, it will be clamped to the end of the buffer. Therefore, the number -of frames you're given may be less than the number you requested. - -After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the -buffer and then "commit" it with `ma_pcm_rb_commit_read()` or `ma_pcm_rb_commit_write()`. This is -where the read/write pointers are updated. When you commit you need to pass in the buffer that was -returned by the earlier call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is -only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and -`ma_pcm_rb_commit_write()` is what's used to increment the pointers, and can be less that what was -originally requested. - -If you want to correct for drift between the write pointer and the read pointer you can use a -combination of `ma_pcm_rb_pointer_distance()`, `ma_pcm_rb_seek_read()` and -`ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only -move the read pointer forward via the consumer thread, and the write pointer forward by the -producer thread. If there is too much space between the pointers, move the read pointer forward. If -there is too little space between the pointers, move the write pointer forward. - -You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` -API. This is exactly the same, only you will use the `ma_rb` functions instead of `ma_pcm_rb` and -instead of frame counts you will pass around byte counts. - -The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most -significant bit being used to encode a loop flag and the internally managed buffers always being -aligned to `MA_SIMD_ALIGNMENT`. - -Note that the ring buffer is only thread safe when used by a single consumer thread and single -producer thread. - - - -15. Backends -============ -The following backends are supported by miniaudio. These are listed in order of default priority. -When no backend is specified when initializing a context or device, miniaudio will attempt to use -each of these backends in the order listed in the table below. - -Note that backends that are not usable by the build target will not be included in the build. For -example, ALSA, which is specific to Linux, will not be included in the Windows build. - - +-------------+-----------------------+--------------------------------------------------------+ - | Name | Enum Name | Supported Operating Systems | - +-------------+-----------------------+--------------------------------------------------------+ - | WASAPI | ma_backend_wasapi | Windows Vista+ | - | DirectSound | ma_backend_dsound | Windows XP+ | - | WinMM | ma_backend_winmm | Windows 95+ | - | Core Audio | ma_backend_coreaudio | macOS, iOS | - | sndio | ma_backend_sndio | OpenBSD | - | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD | - | OSS | ma_backend_oss | FreeBSD | - | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) | - | ALSA | ma_backend_alsa | Linux | - | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) | - | AAudio | ma_backend_aaudio | Android 8+ | - | OpenSL ES | ma_backend_opensl | Android (API level 16+) | - | Web Audio | ma_backend_webaudio | Web (via Emscripten) | - | Custom | ma_backend_custom | Cross Platform | - | Null | ma_backend_null | Cross Platform (not used on Web) | - +-------------+-----------------------+--------------------------------------------------------+ - -Some backends have some nuance details you may want to be aware of. - -15.1. WASAPI ------------- -- Low-latency shared mode will be disabled when using an application-defined sample rate which is - different to the device's native sample rate. To work around this, set `wasapi.noAutoConvertSRC` - to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing - when the `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC - will result in miniaudio's internal resampler being used instead which will in turn enable the - use of low-latency shared mode. - -15.2. PulseAudio ----------------- -- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki: - https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. - Alternatively, consider using a different backend such as ALSA. - -15.3. Android -------------- -- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: - `` -- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a - limitation with OpenSL|ES. -- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration - API (devices are enumerated through Java). You can however perform your own device enumeration - through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it - to ma_device_init(). -- The backend API will perform resampling where possible. The reason for this as opposed to using - miniaudio's built-in resampler is to take advantage of any potential device-specific - optimizations the driver may implement. - -BSD ---- -- The sndio backend is currently only enabled on OpenBSD builds. -- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can - use it. - -15.4. UWP ---------- -- UWP only supports default playback and capture devices. -- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest): - - ``` - - ... - - - - - ``` - -15.5. Web Audio / Emscripten ----------------------------- -- You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build. -- The first time a context is initialized it will create a global object called "miniaudio" whose - primary purpose is to act as a factory for device objects. -- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as - they've been deprecated. -- Google has implemented a policy in their browsers that prevent automatic media output without - first receiving some kind of user input. The following web page has additional details: - https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device - may fail if you try to start playback without first handling some kind of user input. - - - -16. Optimization Tips -===================== -See below for some tips on improving performance. - -16.1. Low Level API -------------------- -- In the data callback, if your data is already clipped prior to copying it into the output buffer, - set the `noClip` config option in the device config to true. This will disable miniaudio's built - in clipping function. -- By default, miniaudio will pre-silence the data callback's output buffer. If you know that you - will always write valid data to the output buffer you can disable pre-silencing by setting the - `noPreSilence` config option in the device config to true. - -16.2. High Level API --------------------- -- If a sound does not require doppler or pitch shifting, consider disabling pitching by - initializing the sound with the `MA_SOUND_FLAG_NO_PITCH` flag. -- If a sound does not require spatialization, disable it by initializing the sound with the - `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. It can be re-enabled again post-initialization with - `ma_sound_set_spatialization_enabled()`. -- If you know all of your sounds will always be the same sample rate, set the engine's sample - rate to match that of the sounds. Likewise, if you're using a self-managed resource manager, - consider setting the decoded sample rate to match your sounds. By configuring everything to - use a consistent sample rate, sample rate conversion can be avoided. - - - -17. Miscellaneous Notes -======================= -- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for - WASAPI and Core Audio, however other backends such as PulseAudio may naturally support it, though - not all have been tested. -- When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This - is due to 64-bit file APIs not being available. -*/ - -#ifndef miniaudio_h -#define miniaudio_h - -#ifdef __cplusplus -extern "C" { -#endif - -#define MA_STRINGIFY(x) #x -#define MA_XSTRINGIFY(x) MA_STRINGIFY(x) - -#define MA_VERSION_MAJOR 0 -#define MA_VERSION_MINOR 11 -#define MA_VERSION_REVISION 21 -#define MA_VERSION_STRING MA_XSTRINGIFY(MA_VERSION_MAJOR) "."

These callbacks are grouped into two parts: context and device. There is one context -to many devices. A device is created from a context. - -The general flow goes like this: - - 1) A context is created with `onContextInit()` - 1a) Available devices can be enumerated with `onContextEnumerateDevices()` if required. - 1b) Detailed information about a device can be queried with `onContextGetDeviceInfo()` if required. - 2) A device is created from the context that was created in the first step using `onDeviceInit()`, and optionally a device ID that was - selected from device enumeration via `onContextEnumerateDevices()`. - 3) A device is started or stopped with `onDeviceStart()` / `onDeviceStop()` - 4) Data is delivered to and from the device by the backend. This is always done based on the native format returned by the prior call - to `onDeviceInit()`. Conversion between the device's native format and the format requested by the application will be handled by - miniaudio internally. - -Initialization of the context is quite simple. You need to do any necessary initialization of internal objects and then output the -callbacks defined in this structure. - -Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which -physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the -given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration -needs to stop and the `onContextEnumerateDevices()` function returns with a success code. - -Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID, -and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the -case when the device ID is NULL, in which case information about the default device needs to be retrieved. - -Once the context has been created and the device ID retrieved (if using anything other than the default device), the device can be created. -This is a little bit more complicated than initialization of the context due to it's more complicated configuration. When initializing a -device, a duplex device may be requested. This means a separate data format needs to be specified for both playback and capture. On input, -the data format is set to what the application wants. On output it's set to the native format which should match as closely as possible to -the requested format. The conversion between the format requested by the application and the device's native format will be handled -internally by miniaudio. - -On input, if the sample format is set to `ma_format_unknown`, the backend is free to use whatever sample format it desires, so long as it's -supported by miniaudio. When the channel count is set to 0, the backend should use the device's native channel count. The same applies for -sample rate. For the channel map, the default should be used when `ma_channel_map_is_blank()` returns true (all channels set to -`MA_CHANNEL_NONE`). On input, the `periodSizeInFrames` or `periodSizeInMilliseconds` option should always be set. The backend should -inspect both of these variables. If `periodSizeInFrames` is set, it should take priority, otherwise it needs to be derived from the period -size in milliseconds (`periodSizeInMilliseconds`) and the sample rate, keeping in mind that the sample rate may be 0, in which case the -sample rate will need to be determined before calculating the period size in frames. On output, all members of the `ma_device_descriptor` -object should be set to a valid value, except for `periodSizeInMilliseconds` which is optional (`periodSizeInFrames` *must* be set). - -Starting and stopping of the device is done with `onDeviceStart()` and `onDeviceStop()` and should be self-explanatory. If the backend uses -asynchronous reading and writing, `onDeviceStart()` and `onDeviceStop()` should always be implemented. - -The handling of data delivery between the application and the device is the most complicated part of the process. To make this a bit -easier, some helper callbacks are available. If the backend uses a blocking read/write style of API, the `onDeviceRead()` and -`onDeviceWrite()` callbacks can optionally be implemented. These are blocking and work just like reading and writing from a file. If the -backend uses a callback for data delivery, that callback must call `ma_device_handle_backend_data_callback()` from within it's callback. -This allows miniaudio to then process any necessary data conversion and then pass it to the miniaudio data callback. - -If the backend requires absolute flexibility with it's data delivery, it can optionally implement the `onDeviceDataLoop()` callback -which will allow it to implement the logic that will run on the audio thread. This is much more advanced and is completely optional. - -The audio thread should run data delivery logic in a loop while `ma_device_get_state() == ma_device_state_started` and no errors have been -encountered. Do not start or stop the device here. That will be handled from outside the `onDeviceDataLoop()` callback. - -The invocation of the `onDeviceDataLoop()` callback will be handled by miniaudio. When you start the device, miniaudio will fire this -callback. When the device is stopped, the `ma_device_get_state() == ma_device_state_started` condition will fail and the loop will be terminated -which will then fall through to the part that stops the device. For an example on how to implement the `onDeviceDataLoop()` callback, -look at `ma_device_audio_thread__default_read_write()`. Implement the `onDeviceDataLoopWakeup()` callback if you need a mechanism to -wake up the audio thread. - -If the backend supports an optimized retrieval of device information from an initialized `ma_device` object, it should implement the -`onDeviceGetInfo()` callback. This is optional, in which case it will fall back to `onContextGetDeviceInfo()` which is less efficient. -*/ -struct ma_backend_callbacks -{ - ma_result (* onContextInit)(ma_context* pContext, const ma_context_config* pConfig, ma_backend_callbacks* pCallbacks); - ma_result (* onContextUninit)(ma_context* pContext); - ma_result (* onContextEnumerateDevices)(ma_context* pContext, ma_enum_devices_callback_proc callback, void* pUserData); - ma_result (* onContextGetDeviceInfo)(ma_context* pContext, ma_device_type deviceType, const ma_device_id* pDeviceID, ma_device_info* pDeviceInfo); - ma_result (* onDeviceInit)(ma_device* pDevice, const ma_device_config* pConfig, ma_device_descriptor* pDescriptorPlayback, ma_device_descriptor* pDescriptorCapture); - ma_result (* onDeviceUninit)(ma_device* pDevice); - ma_result (* onDeviceStart)(ma_device* pDevice); - ma_result (* onDeviceStop)(ma_device* pDevice); - ma_result (* onDeviceRead)(ma_device* pDevice, void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesRead); - ma_result (* onDeviceWrite)(ma_device* pDevice, const void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesWritten); - ma_result (* onDeviceDataLoop)(ma_device* pDevice); - ma_result (* onDeviceDataLoopWakeup)(ma_device* pDevice); - ma_result (* onDeviceGetInfo)(ma_device* pDevice, ma_device_type type, ma_device_info* pDeviceInfo); -}; - -struct ma_context_config -{ - ma_log* pLog; - ma_thread_priority threadPriority; - size_t threadStackSize; - void* pUserData; - ma_allocation_callbacks allocationCallbacks; - struct - { - ma_bool32 useVerboseDeviceEnumeration; - } alsa; - struct - { - const char* pApplicationName; - const char* pServerName; - ma_bool32 tryAutoSpawn; /* Enables autospawning of the PulseAudio daemon if necessary. */ - } pulse; - struct - { - ma_ios_session_category sessionCategory; - ma_uint32 sessionCategoryOptions; - ma_bool32 noAudioSessionActivate; /* iOS only.

The config object is initialized with `ma_context_config_init()`. Individual configuration settings -can then be set directly on the structure. Below are the members of the `ma_context_config` object. - - pLog - A pointer to the `ma_log` to post log messages to. Can be NULL if the application does not - require logging. See the `ma_log` API for details on how to use the logging system. - - threadPriority - The desired priority to use for the audio thread. Allowable values include the following: - - |--------------------------------------| - | Thread Priority | - |--------------------------------------| - | ma_thread_priority_idle | - | ma_thread_priority_lowest | - | ma_thread_priority_low | - | ma_thread_priority_normal | - | ma_thread_priority_high | - | ma_thread_priority_highest (default) | - | ma_thread_priority_realtime | - | ma_thread_priority_default | - |--------------------------------------| - - threadStackSize - The desired size of the stack for the audio thread. Defaults to the operating system's default. - - pUserData - A pointer to application-defined data. This can be accessed from the context object directly such as `context.pUserData`. - - allocationCallbacks - Structure containing custom allocation callbacks. Leaving this at defaults will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. These allocation - callbacks will be used for anything tied to the context, including devices. - - alsa.useVerboseDeviceEnumeration - ALSA will typically enumerate many different devices which can be intrusive and not user-friendly. To combat this, miniaudio will enumerate only unique - card/device pairs by default. The problem with this is that you lose a bit of flexibility and control. Setting alsa.useVerboseDeviceEnumeration makes - it so the ALSA backend includes all devices. Defaults to false. - - pulse.pApplicationName - PulseAudio only. The application name to use when initializing the PulseAudio context with `pa_context_new()`. - - pulse.pServerName - PulseAudio only. The name of the server to connect to with `pa_context_connect()`. - - pulse.tryAutoSpawn - PulseAudio only. Whether or not to try automatically starting the PulseAudio daemon. Defaults to false. If you set this to true, keep in mind that - miniaudio uses a trial and error method to find the most appropriate backend, and this will result in the PulseAudio daemon starting which may be - intrusive for the end user. - - coreaudio.sessionCategory - iOS only. The session category to use for the shared AudioSession instance.

The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it -from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be -playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the -device is done via a callback which is fired by miniaudio at periodic time intervals. - -The frequency at which data is delivered to and from a device depends on the size of it's period. The size of the period can be defined in terms of PCM frames -or milliseconds, whichever is more convenient. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and -increased risk of glitching due to the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but -miniaudio's defaults should work fine for most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple -media player you can make it larger. Note that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the -backend is ultimately responsible for what it gives you. You cannot assume you will get exactly what you ask for. - -When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the -format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you -can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline. - - -Parameters ----------- -pContext (in, optional) - A pointer to the context that owns the device. This can be null, in which case it creates a default context internally. - -pConfig (in) - A pointer to the device configuration. Cannot be null. See remarks for details. - -pDevice (out) - A pointer to the device object being initialized. - - -Return Value ------------- -MA_SUCCESS if successful; any other error code otherwise. - - -Thread Safety -------------- -Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to -calling this at the same time as `ma_device_uninit()`. - - -Callback Safety ---------------- -Unsafe. It is not safe to call this inside any callback. - - -Remarks -------- -Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so: - - ```c - ma_context_init(NULL, 0, NULL, &context); - ``` - -Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use -device.pContext for the initialization of other devices. - -The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can -then be set directly on the structure. Below are the members of the `ma_device_config` object. - - deviceType - Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`. - - sampleRate - The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate. - - periodSizeInFrames - The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will - be used depending on the selected performance profile. This value affects latency. See below for details. - - periodSizeInMilliseconds - The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be - used depending on the selected performance profile. The value affects latency. See below for details. - - periods - The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by - this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured. - - performanceProfile - A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or - `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value. - - noPreSilencedOutputBuffer - When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of - the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data - callback will write to every sample in the output buffer, or if you are doing your own clearing. - - noClip - When set to true, the contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or - not to clip. When set to false (default), the contents of the output buffer passed into the data callback will be clipped after returning. This only - applies when the playback sample format is f32. - - noDisableDenormals - By default, miniaudio will disable denormals when the data callback is called. Setting this to true will prevent the disabling of denormals. - - noFixedSizedCallback - Allows miniaudio to fire the data callback with any frame count. When this is set to false (the default), the data callback will be fired with a - consistent frame count as specified by `periodSizeInFrames` or `periodSizeInMilliseconds`. When set to true, miniaudio will fire the callback with - whatever the backend requests, which could be anything. - - dataCallback - The callback to fire whenever data is ready to be delivered to or from the device. - - notificationCallback - The callback to fire when something has changed with the device, such as whether or not it has been started or stopped. - - pUserData - The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`. - - resampling.algorithm - The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The - default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`. - - resampling.pBackendVTable - A pointer to an optional vtable that can be used for plugging in a custom resampler. - - resampling.pBackendUserData - A pointer that will passed to callbacks in pBackendVTable. - - resampling.linear.lpfOrder - The linear resampler applies a low-pass filter as part of it's processing for anti-aliasing. This setting controls the order of the filter. The higher - the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is - `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`. - - playback.pDeviceID - A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's - default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration. - - playback.format - The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after - initialization from the device object directly with `device.playback.format`. - - playback.channels - The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization - from the device object directly with `device.playback.channels`. - - playback.pChannelMap - The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the - device object direct with `device.playback.pChannelMap`. When set, the buffer should contain `channels` items. - - playback.shareMode - The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify - exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to - ma_share_mode_shared and reinitializing. - - capture.pDeviceID - A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize. Setting this NULL (default) will use the system's - default capture device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration. - - capture.format - The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after - initialization from the device object directly with `device.capture.format`. - - capture.channels - The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization - from the device object directly with `device.capture.channels`. - - capture.pChannelMap - The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the - device object direct with `device.capture.pChannelMap`. When set, the buffer should contain `channels` items. - - capture.shareMode - The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify - exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to - ma_share_mode_shared and reinitializing. - - wasapi.noAutoConvertSRC - WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false. - - wasapi.noDefaultQualitySRC - WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`. - You should usually leave this set to false, which is the default. - - wasapi.noAutoStreamRouting - WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false. - - wasapi.noHardwareOffloading - WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false. - - alsa.noMMap - ALSA only. When set to true, disables MMap mode. Defaults to false. - - alsa.noAutoFormat - ALSA only. When set to true, disables ALSA's automatic format conversion by including the SND_PCM_NO_AUTO_FORMAT flag. Defaults to false. - - alsa.noAutoChannels - ALSA only. When set to true, disables ALSA's automatic channel conversion by including the SND_PCM_NO_AUTO_CHANNELS flag. Defaults to false. - - alsa.noAutoResample - ALSA only. When set to true, disables ALSA's automatic resampling by including the SND_PCM_NO_AUTO_RESAMPLE flag. Defaults to false. - - pulse.pStreamNamePlayback - PulseAudio only. Sets the stream name for playback. - - pulse.pStreamNameCapture - PulseAudio only. Sets the stream name for capture. - - coreaudio.allowNominalSampleRateChange - Core Audio only. Desktop only. When enabled, allows the sample rate of the device to be changed at the operating system level. This - is disabled by default in order to prevent intrusive changes to the user's system. This is useful if you want to use a sample rate - that is known to be natively supported by the hardware thereby avoiding the cost of resampling. When set to true, miniaudio will - find the closest match between the sample rate requested in the device config and the sample rates natively supported by the - hardware. When set to false, the sample rate currently set by the operating system will always be used. - - opensl.streamType - OpenSL only. Explicitly sets the stream type. If left unset (`ma_opensl_stream_type_default`), the - stream type will be left unset. Think of this as the type of audio you're playing. - - opensl.recordingPreset - OpenSL only. Explicitly sets the type of recording your program will be doing. When left - unset, the recording preset will be left unchanged. - - aaudio.usage - AAudio only. Explicitly sets the nature of the audio the program will be consuming. When - left unset, the usage will be left unchanged. - - aaudio.contentType - AAudio only. Sets the content type. When left unset, the content type will be left unchanged. - - aaudio.inputPreset - AAudio only. Explicitly sets the type of recording your program will be doing. When left - unset, the input preset will be left unchanged. - - aaudio.noAutoStartAfterReroute - AAudio only. Controls whether or not the device should be automatically restarted after a - stream reroute. When set to false (default) the device will be restarted automatically; - otherwise the device will be stopped. - - -Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device. - -After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`. - -If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or -`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or -`ma_performance_profile_conservative`. - -If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device -in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the -config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA, -for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user. -Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary. - -When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config -and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run -on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`, -`playback/capture.channels` and `sampleRate` members of the device object. - -When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message -asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information. - -ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture. -If these fail it will try falling back to the "hw" device. - - -Example 1 - Simple Initialization ---------------------------------- -This example shows how to initialize a simple playback device using a standard configuration.

This is a brief description of what's going on -in the PulseAudio backend. I apologize if this gets a bit ranty for your liking - you might want to skip this discussion. - -PulseAudio has something they call the "Simple API", which unfortunately isn't suitable for miniaudio. I've not seen anywhere where it -allows you to enumerate over devices, nor does it seem to support the ability to stop and start streams. Looking at the documentation, it -appears as though the stream is constantly running and you prevent sound from being emitted or captured by simply not calling the read or -write functions. This is not a professional solution as it would be much better to *actually* stop the underlying stream. Perhaps the -simple API has some smarts to do this automatically, but I'm not sure. Another limitation with the simple API is that it seems inefficient -when you want to have multiple streams to a single context. For these reasons, miniaudio is not using the simple API. - -Since we're not using the simple API, we're left with the asynchronous API as our only other option. And boy, is this where it starts to -get fun, and I don't mean that in a good way... - -The problems start with the very name of the API - "asynchronous". Yes, this is an asynchronous oriented API which means your commands -don't immediately take effect. You instead need to issue your commands, and then wait for them to complete. The waiting mechanism is -enabled through the use of a "main loop". In the asychronous API you cannot get away from the main loop, and the main loop is where almost -all of PulseAudio's problems stem from. - -When you first initialize PulseAudio you need an object referred to as "main loop". You can implement this yourself by defining your own -vtable, but it's much easier to just use one of the built-in main loop implementations. There's two generic implementations called -pa_mainloop and pa_threaded_mainloop, and another implementation specific to GLib called pa_glib_mainloop. We're using pa_threaded_mainloop -because it simplifies management of the worker thread. The idea of the main loop object is pretty self explanatory - you're supposed to use -it to implement a worker thread which runs in a loop. The main loop is where operations are actually executed. - -To initialize the main loop, you just use `pa_threaded_mainloop_new()`. This is the first function you'll call. You can then get a pointer -to the vtable with `pa_threaded_mainloop_get_api()` (the main loop vtable is called `pa_mainloop_api`). Again, you can bypass the threaded -main loop object entirely and just implement `pa_mainloop_api` directly, but there's no need for it unless you're doing something extremely -specialized such as if you want to integrate it into your application's existing main loop infrastructure. - -(EDIT 2021-01-26: miniaudio is no longer using `pa_threaded_mainloop` due to this issue: https://github.com/mackron/miniaudio/issues/262. -It is now using `pa_mainloop` which turns out to be a simpler solution anyway. The rest of this rant still applies, however.) - -Once you have your main loop vtable (the `pa_mainloop_api` object) you can create the PulseAudio context. This is very similar to -miniaudio's context and they map to each other quite well. You have one context to many streams, which is basically the same as miniaudio's -one `ma_context` to many `ma_device`s. Here's where it starts to get annoying, however. When you first create the PulseAudio context, which -is done with `pa_context_new()`, it's not actually connected to anything. When you connect, you call `pa_context_connect()`. However, if -you remember, PulseAudio is an asynchronous API. That means you cannot just assume the context is connected after `pa_context_context()` -has returned. You instead need to wait for it to connect. To do this, you need to either wait for a callback to get fired, which you can -set with `pa_context_set_state_callback()`, or you can continuously poll the context's state. Either way, you need to run this in a loop. -All objects from here out are created from the context, and, I believe, you can't be creating these objects until the context is connected. -This waiting loop is therefore unavoidable. In order for the waiting to ever complete, however, the main loop needs to be running. Before -attempting to connect the context, the main loop needs to be started with `pa_threaded_mainloop_start()`. - -The reason for this asynchronous design is to support cases where you're connecting to a remote server, say through a local network or an -internet connection. However, the *VAST* majority of cases don't involve this at all - they just connect to a local "server" running on the -host machine. The fact that this would be the default rather than making `pa_context_connect()` synchronous tends to boggle the mind. - -Once the context has been created and connected you can start creating a stream. A PulseAudio stream is analogous to miniaudio's device. -The initialization of a stream is fairly standard - you configure some attributes (analogous to miniaudio's device config) and then call -`pa_stream_new()` to actually create it. Here is where we start to get into "operations". When configuring the stream, you can get -information about the source (such as sample format, sample rate, etc.), however it's not synchronous. Instead, a `pa_operation` object -is returned from `pa_context_get_source_info_by_name()` (capture) or `pa_context_get_sink_info_by_name()` (playback). Then, you need to -run a loop (again!) to wait for the operation to complete which you can determine via a callback or polling, just like we did with the -context. Then, as an added bonus, you need to decrement the reference counter of the `pa_operation` object to ensure memory is cleaned up. -All of that just to retrieve basic information about a device! - -Once the basic information about the device has been retrieved, miniaudio can now create the stream with `ma_stream_new()`. Like the -context, this needs to be connected. But we need to be careful here, because we're now about to introduce one of the most horrific design -choices in PulseAudio. - -PulseAudio allows you to specify a callback that is fired when data can be written to or read from a stream. The language is important here -because PulseAudio takes it literally, specifically the "can be". You would think these callbacks would be appropriate as the place for -writing and reading data to and from the stream, and that would be right, except when it's not. When you initialize the stream, you can -set a flag that tells PulseAudio to not start the stream automatically. This is required because miniaudio does not auto-start devices -straight after initialization - you need to call `ma_device_start()` manually. The problem is that even when this flag is specified, -PulseAudio will immediately fire it's write or read callback. This is *technically* correct (based on the wording in the documentation) -because indeed, data *can* be written at this point. The problem is that it's not *practical*. It makes sense that the write/read callback -would be where a program will want to write or read data to or from the stream, but when it's called before the application has even -requested that the stream be started, it's just not practical because the program probably isn't ready for any kind of data delivery at -that point (it may still need to load files or whatnot). Instead, this callback should only be fired when the application requests the -stream be started which is how it works with literally *every* other callback-based audio API. Since miniaudio forbids firing of the data -callback until the device has been started (as it should be with *all* callback based APIs), logic needs to be added to ensure miniaudio -doesn't just blindly fire the application-defined data callback from within the PulseAudio callback before the stream has actually been -started. The device state is used for this - if the state is anything other than `ma_device_state_starting` or `ma_device_state_started`, the main data -callback is not fired. - -This, unfortunately, is not the end of the problems with the PulseAudio write callback. Any normal callback based audio API will -continuously fire the callback at regular intervals based on the size of the internal buffer. This will only ever be fired when the device -is running, and will be fired regardless of whether or not the user actually wrote anything to the device/stream. This not the case in -PulseAudio. In PulseAudio, the data callback will *only* be called if you wrote something to it previously. That means, if you don't call -`pa_stream_write()`, the callback will not get fired. On the surface you wouldn't think this would matter because you should be always -writing data, and if you don't have anything to write, just write silence. That's fine until you want to drain the stream. You see, if -you're continuously writing data to the stream, the stream will never get drained! That means in order to drain the stream, you need to -*not* write data to it! But remember, when you don't write data to the stream, the callback won't get fired again! Why is draining -important? Because that's how we've defined stopping to work in miniaudio. In miniaudio, stopping the device requires it to be drained -before returning from ma_device_stop(). So we've stopped the device, which requires us to drain, but draining requires us to *not* write -data to the stream (or else it won't ever complete draining), but not writing to the stream means the callback won't get fired again! - -This becomes a problem when stopping and then restarting the device. When the device is stopped, it's drained, which requires us to *not* -write anything to the stream. But then, since we didn't write anything to it, the write callback will *never* get called again if we just -resume the stream naively. This means that starting the stream requires us to write data to the stream from outside the callback. This -disconnect is something PulseAudio has got seriously wrong - there should only ever be a single source of data delivery, that being the -callback. (I have tried using `pa_stream_flush()` to trigger the write callback to fire, but this just doesn't work for some reason.) - -Once you've created the stream, you need to connect it which involves the whole waiting procedure. This is the same process as the context, -only this time you'll poll for the state with `pa_stream_get_status()`. The starting and stopping of a streaming is referred to as -"corking" in PulseAudio. The analogy is corking a barrel. To start the stream, you uncork it, to stop it you cork it. Personally I think -it's silly - why would you not just call it "starting" and "stopping" like any other normal audio API? Anyway, the act of corking is, you -guessed it, asynchronous. This means you'll need our waiting loop as usual. Again, why this asynchronous design is the default is -absolutely beyond me. Would it really be that hard to just make it run synchronously? - -Teardown is pretty simple (what?!). It's just a matter of calling the relevant `_unref()` function on each object in reverse order that -they were initialized in. - -That's about it from the PulseAudio side. A bit ranty, I know, but they really need to fix that main loop and callback system. They're -embarrassingly unpractical. The main loop thing is an easy fix - have synchronous versions of all APIs. If an application wants these to -run asynchronously, they can execute them in a separate thread themselves. The desire to run these asynchronously is such a niche -requirement - it makes no sense to make it the default. The stream write callback needs to be change, or an alternative provided, that is -constantly fired, regardless of whether or not `pa_stream_write()` has been called, and it needs to take a pointer to a buffer as a -parameter which the program just writes to directly rather than having to call `pa_stream_writable_size()` and `pa_stream_write()`. These -changes alone will change PulseAudio from one of the worst audio APIs to one of the best. -*/ - - -/* -It is assumed pulseaudio.h is available when linking at compile time.

-#endif - -/* -Core Audio - -So far, Core Audio has been the worst backend to work with due to being both unintuitive and having almost no documentation -apart from comments in the headers (which admittedly are quite good). For my own purposes, and for anybody out there whose -needing to figure out how this darn thing works, I'm going to outline a few things here. - -Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be -able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen -that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent -and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the -distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API. - -Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When -retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific -data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the -devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be -the central APIs for retrieving information about the system and specific devices. - -To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a -structure with three variables and is used to identify which property you are getting or setting. The first is the "selector" -which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is -typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and -kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to -kAudioObjectPropertyElementMain in miniaudio's case. I don't know of any cases where this would be set to anything different. - -Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size -of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property -address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the -size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of -AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count. -*/ - -#if defined(MA_APPLE_MOBILE) -static void ma_device__on_notification_interruption_began(ma_device* pDevice) -{ - ma_device__on_notification(ma_device_notification_init(pDevice, ma_device_notification_type_interruption_began));

Since part of it's volume is being emitted - from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would - receive some amount of contribution from front/left speaker.

The pixel data consists of *y scanlines of *x pixels, -// with each pixel consisting of N interleaved 8-bit components; the first -// pixel pointed to is top-left-most in the image. There is no padding between -// image scanlines or between pixels, regardless of format. The number of -// components N is 'desired_channels' if desired_channels is non-zero, or -// *channels_in_file otherwise. If desired_channels is non-zero, -// *channels_in_file has the number of components that _would_ have been -// output otherwise. E.g. if you set desired_channels to 4, you will always -// get RGBA output, but you can check *channels_in_file to see if it's trivially -// opaque because e.g. there were only 3 channels in the source image. -// -// An output image with N components has the following components interleaved -// in this order in each pixel: -// -// N=#comp components -// 1 grey -// 2 grey, alpha -// 3 red, green, blue -// 4 red, green, blue, alpha -// -// If image loading fails for any reason, the return value will be NULL, -// and *x, *y, *channels_in_file will be unchanged. The function -// stbi_failure_reason() can be queried for an extremely brief, end-user -// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS -// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly -// more user-friendly ones. -// -// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized. -// -// To query the width, height and component count of an image without having to -// decode the full file, you can use the stbi_info family of functions: -// -// int x,y,n,ok; -// ok = stbi_info(filename, &x, &y, &n); -// // returns ok=1 and sets x, y, n if image is a supported format, -// // 0 otherwise. -// -// Note that stb_image pervasively uses ints in its public API for sizes, -// including sizes of memory buffers. This is now part of the API and thus -// hard to change without causing breakage. As a result, the various image -// loaders all have certain limits on image size; these differ somewhat -// by format but generally boil down to either just under 2GB or just under -// 1GB. When the decoded image would be larger than this, stb_image decoding -// will fail. -// -// Additionally, stb_image will reject image files that have any of their -// dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, -// which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, -// the only way to have an image with such dimensions load correctly -// is for it to have a rather extreme aspect ratio. Either way, the -// assumption here is that such larger images are likely to be malformed -// or malicious. If you do need to load an image with individual dimensions -// larger than that, and it still fits in the overall size limit, you can -// #define STBI_MAX_DIMENSIONS on your own to be something larger. -// -// =========================================================================== -// -// UNICODE: -// -// If compiling for Windows and you wish to use Unicode filenames, compile -// with -// #define STBI_WINDOWS_UTF8 -// and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert -// Windows wchar_t filenames to utf8. -// -// =========================================================================== -// -// Philosophy -// -// stb libraries are designed with the following priorities: -// -// 1. easy to use -// 2. easy to maintain -// 3. good performance -// -// Sometimes I let "good performance" creep up in priority over "easy to maintain", -// and for best performance I may provide less-easy-to-use APIs that give higher -// performance, in addition to the easy-to-use ones. Nevertheless, it's important -// to keep in mind that from the standpoint of you, a client of this library, -// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. -// -// Some secondary priorities arise directly from the first two, some of which -// provide more explicit reasons why performance can't be emphasized. -// -// - Portable ("ease of use") -// - Small source code footprint ("easy to maintain") -// - No dependencies ("ease of use") -// -// =========================================================================== -// -// I/O callbacks -// -// I/O callbacks allow you to read from arbitrary sources, like packaged -// files or some other source. Data read from callbacks are processed -// through a small internal buffer (currently 128 bytes) to try to reduce -// overhead. -// -// The three functions you must define are "read" (reads some bytes of data), -// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). -// -// =========================================================================== -// -// SIMD support -// -// The JPEG decoder will try to automatically use SIMD kernels on x86 when -// supported by the compiler. For ARM Neon support, you must explicitly -// request it. -// -// (The old do-it-yourself SIMD API is no longer supported in the current -// code.) -// -// On x86, SSE2 will automatically be used when available based on a run-time -// test; if not, the generic C versions are used as a fall-back. On ARM targets, -// the typical path is to have separate builds for NEON and non-NEON devices -// (at least this is true for iOS and Android). Therefore, the NEON support is -// toggled by a build flag: define STBI_NEON to get NEON loops. -// -// If for some reason you do not want to use any of SIMD code, or if -// you have issues compiling it, you can disable it entirely by -// defining STBI_NO_SIMD. -// -// =========================================================================== -// -// HDR image support (disable by defining STBI_NO_HDR) -// -// stb_image supports loading HDR images in general, and currently the Radiance -// .HDR file format specifically. You can still load any file through the existing -// interface; if you attempt to load an HDR file, it will be automatically remapped -// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; -// both of these constants can be reconfigured through this interface: -// -// stbi_hdr_to_ldr_gamma(2.2f); -// stbi_hdr_to_ldr_scale(1.0f); -// -// (note, do not use _inverse_ constants; stbi_image will invert them -// appropriately). -// -// Additionally, there is a new, parallel interface for loading files as -// (linear) floats to preserve the full dynamic range: -// -// float *data = stbi_loadf(filename, &x, &y, &n, 0); -// -// If you load LDR images through this interface, those images will -// be promoted to floating point values, run through the inverse of -// constants corresponding to the above: -// -// stbi_ldr_to_hdr_scale(1.0f); -// stbi_ldr_to_hdr_gamma(2.2f); -// -// Finally, given a filename (or an open file or memory block--see header -// file for details) containing image data, you can query for the "most -// appropriate" interface to use (that is, whether the image is HDR or -// not), using: -// -// stbi_is_hdr(char *filename); -// -// =========================================================================== -// -// iPhone PNG support: -// -// We optionally support converting iPhone-formatted PNGs (which store -// premultiplied BGRA) back to RGB, even though they're internally encoded -// differently. To enable this conversion, call -// stbi_convert_iphone_png_to_rgb(1). -// -// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per -// pixel to remove any premultiplied alpha *only* if the image file explicitly -// says there's premultiplied data (currently only happens in iPhone images, -// and only if iPhone convert-to-rgb processing is on). -// -// =========================================================================== -// -// ADDITIONAL CONFIGURATION -// -// - You can suppress implementation of any of the decoders to reduce -// your code footprint by #defining one or more of the following -// symbols before creating the implementation. -// -// STBI_NO_JPEG -// STBI_NO_PNG -// STBI_NO_BMP -// STBI_NO_PSD -// STBI_NO_TGA -// STBI_NO_GIF -// STBI_NO_HDR -// STBI_NO_PIC -// STBI_NO_PNM (.ppm and .pgm) -// -// - You can request *only* certain decoders and suppress all other ones -// (this will be more forward-compatible, as addition of new decoders -// doesn't require you to disable them explicitly): -// -// STBI_ONLY_JPEG -// STBI_ONLY_PNG -// STBI_ONLY_BMP -// STBI_ONLY_PSD -// STBI_ONLY_TGA -// STBI_ONLY_GIF -// STBI_ONLY_HDR -// STBI_ONLY_PIC -// STBI_ONLY_PNM (.ppm and .pgm) -// -// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still -// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB -// -// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater -// than that size (in either width or height) without further processing. -// This is to let programs in the wild set an upper bound to prevent -// denial-of-service attacks on untrusted data, as one could generate a -// valid image of gigantic dimensions and force stb_image to allocate a -// huge block of memory and spend disproportionate time decoding it.

Call stbiw_convert_wchar_to_utf8 to convert - Windows wchar_t filenames to utf8. - -USAGE: - - There are five functions, one for each image file format: - - int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); - int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); - int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); - int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality); - int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); - - void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically - - There are also five equivalent functions that use an arbitrary write function. You are - expected to open/close your file-equivalent before and after calling these: - - int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); - int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); - int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); - int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); - int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality); - - where the callback is: - void stbi_write_func(void *context, void *data, int size); - - You can configure it with these global variables: - int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE - int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression - int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode - - - You can define STBI_WRITE_NO_STDIO to disable the file variant of these - functions, so the library will not use stdio.h at all. However, this will - also disable HDR writing, because it requires stdio for formatted output. - - Each function returns 0 on failure and non-0 on success. - - The functions create an image file defined by the parameters. The image - is a rectangle of pixels stored from left-to-right, top-to-bottom. - Each pixel contains 'comp' channels of data stored interleaved with 8-bits - per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is - monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. - The *data pointer points to the first byte of the top-left-most pixel. - For PNG, "stride_in_bytes" is the distance in bytes from the first byte of - a row of pixels to the first byte of the next row of pixels. - - PNG creates output files with the same number of components as the input. - The BMP format expands Y to RGB in the file format and does not - output alpha. - - PNG supports writing rectangles of data even when the bytes storing rows of - data are not consecutive in memory (e.g. sub-rectangles of a larger image), - by supplying the stride between the beginning of adjacent rows. The other - formats do not. (Thus you cannot write a native-format BMP through the BMP - writer, both because it is in BGR order and because it may have padding - at the end of the line.) - - PNG allows you to set the deflate compression level by setting the global - variable 'stbi_write_png_compression_level' (it defaults to 8). - - HDR expects linear float data. Since the format is always 32-bit rgb(e) - data, alpha (if provided) is discarded, and for monochrome data it is - replicated across all three channels. - - TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed - data, set the global variable 'stbi_write_tga_with_rle' to 0. - - JPEG does ignore alpha channels in input data; quality is between 1 and 100. - Higher quality looks better but results in a bigger image. - JPEG baseline (no JPEG progressive). - -CREDITS: - - - Sean Barrett - PNG/BMP/TGA - Baldur Karlsson - HDR - Jean-Sebastien Guay - TGA monochrome - Tim Kelsey - misc enhancements - Alan Hickman - TGA RLE - Emmanuel Julien - initial file IO callback implementation - Jon Olick - original jo_jpeg.cpp code - Daniel Gibson - integrate JPEG, allow external zlib - Aarni Koskela - allow choosing PNG filter - - bugfixes: - github:Chribba - Guillaume Chereau - github:jry2 - github:romigrou - Sergio Gonzalez - Jonas Karlsson - Filip Wasil - Thatcher Ulrich - github:poppolopoppo - Patrick Boettcher - github:xeekworx - Cap Petschulat - Simon Rodriguez - Ivan Tikhonov - github:ignotion - Adam Schackart - Andrew Kensler - -LICENSE - - See end of file for license information. - -*/ - -#ifndef INCLUDE_STB_IMAGE_WRITE_H -#define INCLUDE_STB_IMAGE_WRITE_H - -#include - -// if STB_IMAGE_WRITE_STATIC causes problems, try defining STBIWDEF to 'inline' or 'static inline' -#ifndef STBIWDEF -#ifdef STB_IMAGE_WRITE_STATIC -#define STBIWDEF static -#else -#ifdef __cplusplus -#define STBIWDEF extern "C" -#else -#define STBIWDEF extern -#endif -#endif -#endif - -#ifndef STB_IMAGE_WRITE_STATIC // C++ forbids static forward declarations -STBIWDEF int stbi_write_tga_with_rle;
