GNU Free Documentation License
Version 1.2, November 2002
Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
0. PREAMBLE
The purpose of this License is to make a manual, textbook, or other
functional and useful document "free" in the sense of freedom: to
assure everyone the effective freedom to copy and redistribute it,
with or without modifying it, either commercially or noncommercially.
Secondarily, this License preserves for the author and publisher a way
to get credit for their work, while not being considered responsible
for modifications made by others.
This License is a kind of "copyleft", which means that derivative
works of the document must themselves be free in the same sense. It
complements the GNU General Public License, which is a copyleft
license designed for free software.
We have designed this License in order to use it for manuals for free
software, because free software needs free documentation: a free
program should come with manuals providing the same freedoms that the
software does. But this License is not limited to software manuals;
it can be used for any textual work, regardless of subject matter or
whether it is published as a printed book. We recommend this License
principally for works whose purpose is instruction or reference.
1. APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work, in any medium, that
contains a notice placed by the copyright holder saying it can be
distributed under the terms of this License. Such a notice grants a
world-wide, royalty-free license, unlimited in duration, to use that
work under the conditions stated herein. The "Document", below,
refers to any such manual or work. Any member of the public is a
licensee, and is addressed as "you". You accept the license if you
copy, modify or distribute the work in a way requiring permission
under copyright law.
A "Modified Version" of the Document means any work containing the
Document or a portion of it, either copied verbatim, or with
modifications and/or translated into another language.
A "Secondary Section" is a named appendix or a front-matter section of
the Document that deals exclusively with the relationship of the
publishers or authors of the Document to the Document's overall subject
(or to related matters) and contains nothing that could fall directly
within that overall subject. (Thus, if the Document is in part a
textbook of mathematics, a Secondary Section may not explain any
mathematics.) The relationship could be a matter of historical
connection with the subject or with related matters, or of legal,
commercial, philosophical, ethical or political position regarding
them.
The "Invariant Sections" are certain Secondary Sections whose titles
are designated, as being those of Invariant Sections, in the notice
that says that the Document is released under this License. If a
section does not fit the above definition of Secondary then it is not
allowed to be designated as Invariant. The Document may contain zero
Invariant Sections. If the Document does not identify any Invariant
Sections then there are none.
The "Cover Texts" are certain short passages of text that are listed,
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
the Document is released under this License. A Front-Cover Text may
be at most 5 words, and a Back-Cover Text may be at most 25 words.
A "Transparent" copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the
general public, that is suitable for revising the document
straightforwardly with generic text editors or (for images composed of
pixels) generic paint programs or (for drawings) some widely available
drawing editor, and that is suitable for input to text formatters or
for automatic translation to a variety of formats suitable for input
to text formatters. A copy made in an otherwise Transparent file
format whose markup, or absence of markup, has been arranged to thwart
or discourage subsequent modification by readers is not Transparent.
An image format is not Transparent if used for any substantial amount
of text. A copy that is not "Transparent" is called "Opaque".
Examples of suitable formats for Transparent copies include plain
ASCII without markup, Texinfo input format, LaTeX input format, SGML
or XML using a publicly available DTD, and standard-conforming simple
HTML, PostScript or PDF designed for human modification. Examples of
transparent image formats include PNG, XCF and JPG. Opaque formats
include proprietary formats that can be read and edited only by
proprietary word processors, SGML or XML for which the DTD and/or
processing tools are not generally available, and the
machine-generated HTML, PostScript or PDF produced by some word
processors for output purposes only.
The "Title Page" means, for a printed book, the title page itself,
plus such following pages as are needed to hold, legibly, the material
this License requires to appear in the title page. For works in
formats which do not have any title page as such, "Title Page" means
the text near the most prominent appearance of the work's title,
preceding the beginning of the body of the text.
A section "Entitled XYZ" means a named subunit of the Document whose
title either is precisely XYZ or contains XYZ in parentheses following
text that translates XYZ in another language. (Here XYZ stands for a
specific section name mentioned below, such as "Acknowledgements",
"Dedications", "Endorsements", or "History".) To "Preserve the Title"
of such a section when you modify the Document means that it remains a
section "Entitled XYZ" according to this definition.
The Document may include Warranty Disclaimers next to the notice which
states that this License applies to the Document. These Warranty
Disclaimers are considered to be included by reference in this
License, but only as regards disclaiming warranties: any other
implication that these Warranty Disclaimers may have is void and has
no effect on the meaning of this License.
2. VERBATIM COPYING
You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the
copyright notices, and the license notice saying this License applies
to the Document are reproduced in all copies, and that you add no other
conditions whatsoever to those of this License. You may not use
technical measures to obstruct or control the reading or further
copying of the copies you make or distribute. However, you may accept
compensation in exchange for copies. If you distribute a large enough
number of copies you must also follow the conditions in section 3.
You may also lend copies, under the same conditions stated above, and
you may publicly display copies.
3. COPYING IN QUANTITY
If you publish printed copies (or copies in media that commonly have
printed covers) of the Document, numbering more than 100, and the
Document's license notice requires Cover Texts, you must enclose the
copies in covers that carry, clearly and legibly, all these Cover
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
the back cover. Both covers must also clearly and legibly identify
you as the publisher of these copies. The front cover must present
the full title with all words of the title equally prominent and
visible. You may add other material on the covers in addition.
Copying with changes limited to the covers, as long as they preserve
the title of the Document and satisfy these conditions, can be treated
as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit
legibly, you should put the first ones listed (as many as fit
reasonably) on the actual cover, and continue the rest onto adjacent
pages.
If you publish or distribute Opaque copies of the Document numbering
more than 100, you must either include a machine-readable Transparent
copy along with each Opaque copy, or state in or with each Opaque copy
a computer-network location from which the general network-using
public has access to download using public-standard network protocols
a complete Transparent copy of the Document, free of added material.
If you use the latter option, you must take reasonably prudent steps,
when you begin distribution of Opaque copies in quantity, to ensure
that this Transparent copy will remain thus accessible at the stated
location until at least one year after the last time you distribute an
Opaque copy (directly or through your agents or retailers) of that
edition to the public.
It is requested, but not required, that you contact the authors of the
Document well before redistributing any large number of copies, to give
them a chance to provide you with an updated version of the Document.
4. MODIFICATIONS
You may copy and distribute a Modified Version of the Document under
the conditions of sections 2 and 3 above, provided that you release
the Modified Version under precisely this License, with the Modified
Version filling the role of the Document, thus licensing distribution
and modification of the Modified Version to whoever possesses a copy
of it. In addition, you must do these things in the Modified Version:
A. Use in the Title Page (and on the covers, if any) a title distinct
from that of the Document, and from those of previous versions
(which should, if there were any, be listed in the History section
of the Document). You may use the same title as a previous version
if the original publisher of that version gives permission.
B. List on the Title Page, as authors, one or more persons or entities
responsible for authorship of the modifications in the Modified
Version, together with at least five of the principal authors of the
Document (all of its principal authors, if it has fewer than five),
unless they release you from this requirement.
C. State on the Title page the name of the publisher of the
Modified Version, as the publisher.
D. Preserve all the copyright notices of the Document.
E. Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
F. Include, immediately after the copyright notices, a license notice
giving the public permission to use the Modified Version under the
terms of this License, in the form shown in the Addendum below.
G. Preserve in that license notice the full lists of Invariant Sections
and required Cover Texts given in the Document's license notice.
H. Include an unaltered copy of this License.
I. Preserve the section Entitled "History", Preserve its Title, and add
to it an item stating at least the title, year, new authors, and
publisher of the Modified Version as given on the Title Page. If
there is no section Entitled "History" in the Document, create one
stating the title, year, authors, and publisher of the Document as
given on its Title Page, then add an item describing the Modified
Version as stated in the previous sentence.
J. Preserve the network location, if any, given in the Document for
public access to a Transparent copy of the Document, and likewise
the network locations given in the Document for previous versions
it was based on. These may be placed in the "History" section.
You may omit a network location for a work that was published at
least four years before the Document itself, or if the original
publisher of the version it refers to gives permission.
K. For any section Entitled "Acknowledgements" or "Dedications",
Preserve the Title of the section, and preserve in the section all
the substance and tone of each of the contributor acknowledgements
and/or dedications given therein.
L. Preserve all the Invariant Sections of the Document,
unaltered in their text and in their titles. Section numbers
or the equivalent are not considered part of the section titles.
M. Delete any section Entitled "Endorsements". Such a section
may not be included in the Modified Version.
N. Do not retitle any existing section to be Entitled "Endorsements"
or to conflict in title with any Invariant Section.
O. Preserve any Warranty Disclaimers.
If the Modified Version includes new front-matter sections or
appendices that qualify as Secondary Sections and contain no material
copied from the Document, you may at your option designate some or all
of these sections as invariant. To do this, add their titles to the
list of Invariant Sections in the Modified Version's license notice.
These titles must be distinct from any other section titles.
You may add a section Entitled "Endorsements", provided it contains
nothing but endorsements of your Modified Version by various
parties--for example, statements of peer review or that the text has
been approved by an organization as the authoritative definition of a
standard.
You may add a passage of up to five words as a Front-Cover Text, and a
passage of up to 25 words as a Back-Cover Text, to the end of the list
of Cover Texts in the Modified Version. Only one passage of
Front-Cover Text and one of Back-Cover Text may be added by (or
through arrangements made by) any one entity. If the Document already
includes a cover text for the same cover, previously added by you or
by arrangement made by the same entity you are acting on behalf of,
you may not add another; but you may replace the old one, on explicit
permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License
give permission to use their names for publicity for or to assert or
imply endorsement of any Modified Version.
5. COMBINING DOCUMENTS
You may combine the Document with other documents released under this
License, under the terms defined in section 4 above for modified
versions, provided that you include in the combination all of the
Invariant Sections of all of the original documents, unmodified, and
list them all as Invariant Sections of your combined work in its
license notice, and that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy. If there are multiple Invariant Sections with the same name but
different contents, make the title of each such section unique by
adding at the end of it, in parentheses, the name of the original
author or publisher of that section if known, or else a unique number.
Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections Entitled "History"
in the various original documents, forming one section Entitled
"History"; likewise combine any sections Entitled "Acknowledgements",
and any sections Entitled "Dedications". You must delete all sections
Entitled "Endorsements".
6. COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents
released under this License, and replace the individual copies of this
License in the various documents with a single copy that is included in
the collection, provided that you follow the rules of this License for
verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute
it individually under this License, provided you insert a copy of this
License into the extracted document, and follow this License in all
other respects regarding verbatim copying of that document.
7. AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate
and independent documents or works, in or on a volume of a storage or
distribution medium, is called an "aggregate" if the copyright
resulting from the compilation is not used to limit the legal rights
of the compilation's users beyond what the individual works permit.
When the Document is included in an aggregate, this License does not
apply to the other works in the aggregate which are not themselves
derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half of
the entire aggregate, the Document's Cover Texts may be placed on
covers that bracket the Document within the aggregate, or the
electronic equivalent of covers if the Document is in electronic form.
Otherwise they must appear on printed covers that bracket the whole
aggregate.
8. TRANSLATION
Translation is considered a kind of modification, so you may
distribute translations of the Document under the terms of section 4.
Replacing Invariant Sections with translations requires special
permission from their copyright holders, but you may include
translations of some or all Invariant Sections in addition to the
original versions of these Invariant Sections. You may include a
translation of this License, and all the license notices in the
Document, and any Warranty Disclaimers, provided that you also include
the original English version of this License and the original versions
of those notices and disclaimers. In case of a disagreement between
the translation and the original version of this License or a notice
or disclaimer, the original version will prevail.
If a section in the Document is Entitled "Acknowledgements",
"Dedications", or "History", the requirement (section 4) to Preserve
its Title (section 1) will typically require changing the actual
title.
9. TERMINATION
You may not copy, modify, sublicense, or distribute the Document except
as expressly provided for under this License. Any other attempt to
copy, modify, sublicense or distribute the Document is void, and will
automatically terminate your rights under this License. However,
parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such
parties remain in full compliance.
10. FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions
of the GNU Free Documentation License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns. See
http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number.
If the Document specifies that a particular numbered version of this
License "or any later version" applies to it, you have the option of
following the terms and conditions either of that specified version or
of any later version that has been published (not as a draft) by the
Free Software Foundation. If the Document does not specify a version
number of this License, you may choose any version ever published (not
as a draft) by the Free Software Foundation.
ADDENDUM: How to use this License for your documents
To use this License in a document you have written, include a copy of
the License in the document and put the following copyright and
license notices just after the title page:
Copyright (c) YEAR YOUR NAME.
Permission is granted to copy, distribute and/or modify this document
under the terms of the GNU Free Documentation License, Version 1.2
or any later version published by the Free Software Foundation;
with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
A copy of the license is included in the section entitled "GNU
Free Documentation License".
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
replace the "with...Texts." line with this:
with the Invariant Sections being LIST THEIR TITLES, with the
Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.
If your document contains nontrivial examples of program code, we
recommend releasing these examples in parallel under your choice of
free software license, such as the GNU General Public License,
to permit their use in free software.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

# Free Lossless Audio Codec (FLAC)
FLAC is open source software that can reduce the amount of storage space
needed to store digital audio signals without needing to remove
information in doing so.
The files read and produced by this software are called FLAC files. As
these files (which follow the [FLAC format](https://xiph.org/flac/format.html))
can be read from and written to by other software as well, this software
is often referred to as the FLAC reference implementation.
FLAC has been developed by volunteers. If you want to help out, see
CONTRIBUTING.md for more information.
## Components
FLAC is comprised of
* libFLAC, a library which implements reference encoders and
decoders for native FLAC and Ogg FLAC, and a metadata interface
* libFLAC++, a C++ object wrapper library around libFLAC
* `flac`, a command-line program for encoding and decoding files
* `metaflac`, a command-line program for viewing and editing FLAC
metadata
* user and API documentation
The libraries (libFLAC, libFLAC++) are licensed under Xiph.org's
BSD-like license (see COPYING.Xiph). All other programs and plugins are
licensed under the GNU General Public License (see COPYING.GPL). The
documentation is licensed under the GNU Free Documentation License
(see COPYING.FDL).
## Documentation
For documentation of the `flac` and `metaflac` command line tools, see
the directory man, which contains the files flac.md and metaflac.md
The API documentation is in html and is generated by Doxygen. It can be
found in the directory doc/html/api. It is included in a release tarball
and must be build with Doxygen when the source is taken directly from
git.
The directory examples contains example source code on using libFLAC and
libFLAC++.
Documentation concerning the FLAC format itself (which can be used to
create software reading and writing FLAC software independent from
libFLAC) was included in previous releases, but can now be found on
https://datatracker.ietf.org/doc/draft-ietf-cellar-flac/ Additionally
a set of files for conformance testing called the FLAC decoder testbench
can be found at https://github.com/ietf-wg-cellar/flac-test-files
If you have questions about FLAC that this document does not answer,
please submit them at the following tracker so this document can be
improved:

## Building FLAC
All components of the FLAC project can be build with a variety of
compilers (including GCC, Clang, Visual Studio, Intel C++ Compiler) on
many architectures (inluding x86, x86_64, ARMv7, ARMv8 and PowerPC)
for many different operating systems.
To do this, FLAC provides two build systems: one using GNU's autotools
and one with CMake. Both differ slighly in configuration options, but
should be considered equivalent for most use cases.
FLAC used to provide files specifically for building with Visual Studio,
but these have been removed in favor of using CMake.
## Building with CMake
CMake is a cross-platform build system. FLAC can be built on Windows,
Linux, Mac OS X using CMake.
You can use either CMake's CLI or GUI. We recommend you to have a
separate build folder outside the repository in order to not spoil it
with generated files. It is possible however to do a so-called in-tree
build, in that case /path/to/flac-build in the following examples is
equal to /path/to/flac-source.
### CMake CLI
Go to your build folder and run something like this:
```
/path/to/flac-build$ cmake /path/to/flac-source
```
or e.g. in Windows shell
```
C:\path\to\flac-build> cmake \path\to\flac-source
```
(provided that cmake is in your %PATH% variable)
That will generate build scripts for the default build system (e.g.
Makefiles for UNIX). After that you start build with a command like
this:
```
/path/to/flac-build$ make
```
And afterwards you can run tests or install the built libraries and
headers
```
/path/to/flac-build$ make test
/path/to/flac-build$ make install
```
If you want use a build system other than default add -G flag to cmake,
e.g.:
```
/path/to/flac-build$ cmake /path/to/flac-source -GNinja
/path/to/flac-build$ ninja
```
or:
```
/path/to/flac-build$ cmake /path/to/flac-source -GXcode
```
Use cmake --help to see the list of available generators.
By default CMake will search for OGG. If CMake fails to find it you can
help CMake by specifying the exact path:
```
/path/to/flac-build$ cmake /path/to/flac-source -DOGG_ROOT=/path/to/ogg
```
If you would like CMake to build OGG alongside FLAC, you can place the
ogg sources directly in the flac source directory as a subdirectory with
the name ogg, for example:
```
/path/to/flac-source/ogg
```
If you don't want to build flac with OGG support you can tell CMake not
to look for OGG:
```
/path/to/flac-build$ cmake /path/to/flac-source -DWITH_OGG=OFF
```
Other FLAC's options (e.g. building C++ lib or docs) can also be put to
cmake through -D flag. If you want to know what options are available,
use -LH:
```
/path/to/flac-build$ cmake /path/to/flac-source -LH
```
### CMake GUI (for Visual Studio)
It is likely that you would prefer to use the CMake GUI if you use
Visual Studio to build FLAC. It's in essence the same process as
building using CLI.
Open cmake-gui. In the window select a source directory (the
repository's root), a build directory (some other directory outside the
repository). Then press button "Configure". CMake will ask you which
build system you prefer. Choose that version of Visual Studio which you
have on your system, choose whether you want to build for Win32 or x64.
Press OK.
After CMake finishes you can change the configuration to your liking and
if you change anything, run Configure again. With the "Generate" button,
CMake creates Visual Studio files, which can be opened from Visual
Studio. With the button "Open Project" CMake will launch Visual Studio
and open the generated solution. You can use the project files as usual
but remember that they were generated by CMake. That means that your
changes (e.g. some additional compile flags) will be lost when you run
CMake next time.
CMake searches by default for OGG on your system and returns an error
if it cannot find it. If you want to build OGG alongside FLAC, you can
download the OGG sources and extract them in a subdirectory of the FLAC
source directory with the name ogg (i.e. /path/to/flac-source/ogg)
before running CMake. If you don't want to build FLAC with OGG support,
untick the box following WITH_OGG flag in the list of variables in
cmake-gui window and run "Configure" again.
If CMake fails to find MSVC compiler then running cmake-gui from MS
Developer comand prompt should help.
## Building with GNU autotools
FLAC uses autoconf and libtool for configuring and building. To
configure a build, open a commmand line/terminal and run `./configure`
You can provide options to this command, which are listed by running
`./configure --help`.
In case the configure script is not present (for example when building
from git and not from a release tarball), it can be generated by running
`./autogen.sh`. This may require a libtool development package though.
After configuration, build with `make`, verify the build with
`make check` and install with `make install`. Installation might require
administrator priviledged, i.e. `sudo make install`.
The 'make check' step is optional; omit it to skip all the tests, which
can take about an hour to complete. Even though it will stop with an
explicit message on any failure, it does print out a lot of stuff so you
might want to capture the output to a file if you're having a problem.
Also, don't run 'make check' as root because it confuses some of the
tests.
Summarizing:
```
./configure
make && make check
sudo make install
```
## Note to embedded developers
libFLAC has grown larger over time as more functionality has been
included, but much of it may be unnecessary for a particular embedded
implementation. Unused parts may be pruned by some simple editing of
configure.ac and src/libFLAC/Makefile.am; the following dependency
graph shows which modules may be pruned without breaking things
further down:
```
metadata.h
stream_decoder.h
format.h
stream_encoder.h
stream_decoder.h
format.h
stream_decoder.h
format.h
```
In other words, for pure decoding applications, both the stream encoder
and metadata editing interfaces can be safely removed. Note that this
is specific to building the libraries for embedded use. The command line
tools do not provide such compartmentalization, and require a complete
libFLAC build to function.
There is a section dedicated to embedded use in the libFLAC API
HTML documentation (see doc/html/api/index.html).
Also, there are several places in the libFLAC code with comments marked
with "OPT:" where a #define can be changed to enable code that might be
faster on a specific platform. Experimenting with these can yield
faster binaries.

* \brief
* This module describes the encoder layers provided by libFLAC++.
*
* The libFLAC++ encoder classes are object wrappers around their
* counterparts in libFLAC. All encoding layers available in
* libFLAC are also provided here. The interface is very similar;
* make sure to read the \link flac_encoder libFLAC encoder module \endlink.
*
* There are only two significant differences here. First, instead of
* passing in C function pointers for callbacks, you inherit from the
* encoder class and provide implementations for the callbacks in your
* derived class; because of this there is no need for a 'client_data'
* property.
*
* Second, there are two stream encoder classes. FLAC::Encoder::Stream
* is used for the same cases that FLAC__stream_encoder_init_stream() /
* FLAC__stream_encoder_init_ogg_stream() are used, and FLAC::Encoder::File
* is used for the same cases that
* FLAC__stream_encoder_init_FILE() and FLAC__stream_encoder_init_file() /
* FLAC__stream_encoder_init_ogg_FILE() and FLAC__stream_encoder_init_ogg_file()
* are used.

*
* \section intro Introduction
*
* This is the documentation for the FLAC C and C++ APIs. It is
* highly interconnected; this introduction should give you a top
* level idea of the structure and how to find the information you
* need. As a prerequisite you should have at least a basic
* knowledge of the FLAC format, documented
* <A HREF="https://xiph.org/flac/format.html">here</A>.
*
* \section c_api FLAC C API
*
* The FLAC C API is the interface to libFLAC, a set of structures
* describing the components of FLAC streams, and functions for
* encoding and decoding streams, as well as manipulating FLAC
* metadata in files. The public include files will be installed
* in your include area (for example /usr/include/FLAC/...).
*
* By writing a little code and linking against libFLAC, it is
* relatively easy to add FLAC support to another program. The
* library is licensed under <A HREF="https://xiph.org/flac/license.html">Xiph's BSD license</A>.
* Complete source code of libFLAC as well as the command-line
* encoder and plugins is available and is a useful source of
* examples.
*
* Aside from encoders and decoders, libFLAC provides a powerful
* metadata interface for manipulating metadata in FLAC files. It
* allows the user to add, delete, and modify FLAC metadata blocks
* and it can automatically take advantage of PADDING blocks to avoid
* rewriting the entire FLAC file when changing the size of the
* metadata.
*
* libFLAC usually only requires the standard C library and C math
* library. In particular, threading is not used so there is no
* dependency on a thread library. However, libFLAC does not use
* global variables and should be thread-safe.
*
* libFLAC also supports encoding to and decoding from Ogg FLAC.
* However the metadata editing interfaces currently have limited
* read-only support for Ogg FLAC files.
*
* \section cpp_api FLAC C++ API
*
* The FLAC C++ API is a set of classes that encapsulate the
* structures and functions in libFLAC. They provide slightly more
* functionality with respect to metadata but are otherwise
* equivalent. For the most part, they share the same usage as
* their counterparts in libFLAC, and the FLAC C API documentation
* can be used as a supplement. The public include files
* for the C++ API will be installed in your include area (for
* example /usr/include/FLAC++/...).
*
* libFLAC++ is also licensed under
* <A HREF="https://xiph.org/flac/license.html">Xiph's BSD license</A>.
*
* \section getting_started Getting Started
*
* A good starting point for learning the API is to browse through
* the <A HREF="modules.html">modules</A>. Modules are logical
* groupings of related functions or classes, which correspond roughly
* to header files or sections of header files. Each module includes a
* detailed description of the general usage of its functions or
* classes.
*
* From there you can go on to look at the documentation of
* individual functions. You can see different views of the individual
* functions through the links in top bar across this page.
*
* If you prefer a more hands-on approach, you can jump right to some
* <A HREF="https://xiph.org/flac/documentation_example_code.html">example code</A>.
*
* \section porting_guide Porting Guide
*
* Starting with FLAC 1.1.3 a \link porting Porting Guide \endlink
* has been introduced which gives detailed instructions on how to
* port your code to newer versions of FLAC.
*
* \section embedded_developers Embedded Developers
*
* libFLAC has grown larger over time as more functionality has been
* included, but much of it may be unnecessary for a particular embedded
* implementation. Unused parts may be pruned by some simple editing of
* src/libFLAC/Makefile.am. In general, the decoders, encoders, and
* metadata interface are all independent from each other.
*
* It is easiest to just describe the dependencies:
*
* - All modules depend on the \link flac_format Format \endlink module.
* - The decoders and encoders depend on the bitbuffer.
* - The decoder is independent of the encoder. The encoder uses the
* decoder because of the verify feature, but this can be removed if
* not needed.
* - Parts of the metadata interface require the stream decoder (but not
* the encoder).
* - Ogg support is selectable through the compile time macro
* \c FLAC__HAS_OGG.
*
* For example, if your application only requires the stream decoder, no
* encoder, and no metadata interface, you can remove the stream encoder
* and the metadata interface, which will greatly reduce the size of the
* library.
*
* Also, there are several places in the libFLAC code with comments marked
* with "OPT:" where a \#define can be changed to enable code that might be
* faster on a specific platform. Experimenting with these can yield faster
* binaries.
*/
/** \defgroup porting Porting Guide for New Versions
*
* This module describes differences in the library interfaces from
* version to version. It assists in the porting of code that uses
* the libraries to newer versions of FLAC.
*
* One simple facility for making porting easier that has been added
* in FLAC 1.1.3 is a set of \#defines in \c export.h of each
* library's includes (e.g. \c include/FLAC/export.h). The
* \#defines mirror the libraries'
* <A HREF="http://www.gnu.org/software/libtool/manual/libtool.html#Libtool-versioning">libtool version numbers</A>,
* e.g. in libFLAC there are \c FLAC_API_VERSION_CURRENT,
* \c FLAC_API_VERSION_REVISION, and \c FLAC_API_VERSION_AGE.
* These can be used to support multiple versions of an API during the
* transition phase, e.g.
*
* \code
* #if !defined(FLAC_API_VERSION_CURRENT) || FLAC_API_VERSION_CURRENT <= 7
* legacy code
* #else
* new code
* #endif
* \endcode
*
* The source will work for multiple versions and the legacy code can
* easily be removed when the transition is complete.
*
* Another available symbol is FLAC_API_SUPPORTS_OGG_FLAC (defined in
* include/FLAC/export.h), which can be used to determine whether or not
* the library has been compiled with support for Ogg FLAC. This is
* simpler than trying to call an Ogg init function and catching the
* error.
*/
/** \defgroup porting_1_1_2_to_1_1_3 Porting from FLAC 1.1.2 to 1.1.3
* \ingroup porting
*
* \brief
* This module describes porting from FLAC 1.1.2 to FLAC 1.1.3.
*
* The main change between the APIs in 1.1.2 and 1.1.3 is that they have
* been simplified. First, libOggFLAC has been merged into libFLAC and
* libOggFLAC++ has been merged into libFLAC++. Second, both the three
* decoding layers and three encoding layers have been merged into a
* single stream decoder and stream encoder. That is, the functionality
* of FLAC__SeekableStreamDecoder and FLAC__FileDecoder has been merged
* into FLAC__StreamDecoder, and FLAC__SeekableStreamEncoder and
* FLAC__FileEncoder into FLAC__StreamEncoder. Only the
* FLAC__StreamDecoder and FLAC__StreamEncoder remain. What this means
* is there is now a single API that can be used to encode or decode
* streams to/from native FLAC or Ogg FLAC and the single API can work
* on both seekable and non-seekable streams.
*
* Instead of creating an encoder or decoder of a certain layer, now the
* client will always create a FLAC__StreamEncoder or
* FLAC__StreamDecoder. The old layers are now differentiated by the
* initialization function. For example, for the decoder,
* FLAC__stream_decoder_init() has been replaced by
* FLAC__stream_decoder_init_stream(). This init function takes
* callbacks for the I/O, and the seeking callbacks are optional. This
* allows the client to use the same object for seekable and
* non-seekable streams. For decoding a FLAC file directly, the client
* can use FLAC__stream_decoder_init_file() and pass just a filename
* and fewer callbacks; most of the other callbacks are supplied
* internally. For situations where fopen()ing by filename is not
* possible (e.g. Unicode filenames on Windows) the client can instead
* open the file itself and supply the FILE* to
* FLAC__stream_decoder_init_FILE(). The init functions now returns a
* FLAC__StreamDecoderInitStatus instead of FLAC__StreamDecoderState.
* Since the callbacks and client data are now passed to the init
* function, the FLAC__stream_decoder_set_*_callback() functions and
* FLAC__stream_decoder_set_client_data() are no longer needed. The
* rest of the calls to the decoder are the same as before.
*
* There are counterpart init functions for Ogg FLAC, e.g.
* FLAC__stream_decoder_init_ogg_stream(). All the rest of the calls
* and callbacks are the same as for native FLAC.
*
* As an example, in FLAC 1.1.2 a seekable stream decoder would have
* been set up like so:
*
* \code
* FLAC__SeekableStreamDecoder *decoder = FLAC__seekable_stream_decoder_new();
* if(decoder == NULL) do_something;
* FLAC__seekable_stream_decoder_set_md5_checking(decoder, true);
* [... other settings ...]
* FLAC__seekable_stream_decoder_set_read_callback(decoder, my_read_callback);
* FLAC__seekable_stream_decoder_set_seek_callback(decoder, my_seek_callback);
* FLAC__seekable_stream_decoder_set_tell_callback(decoder, my_tell_callback);
* FLAC__seekable_stream_decoder_set_length_callback(decoder, my_length_callback);
* FLAC__seekable_stream_decoder_set_eof_callback(decoder, my_eof_callback);
* FLAC__seekable_stream_decoder_set_write_callback(decoder, my_write_callback);
* FLAC__seekable_stream_decoder_set_metadata_callback(decoder, my_metadata_callback);
* FLAC__seekable_stream_decoder_set_error_callback(decoder, my_error_callback);
* FLAC__seekable_stream_decoder_set_client_data(decoder, my_client_data);
* if(FLAC__seekable_stream_decoder_init(decoder) != FLAC__SEEKABLE_STREAM_DECODER_OK) do_something;
* \endcode
*
* In FLAC 1.1.3 it is like this:
*
* \code
* FLAC__StreamDecoder *decoder = FLAC__stream_decoder_new();
* if(decoder == NULL) do_something;
* FLAC__stream_decoder_set_md5_checking(decoder, true);
* [... other settings ...]
* if(FLAC__stream_decoder_init_stream(
* decoder,
* my_read_callback,
* my_seek_callback, // or NULL
* my_tell_callback, // or NULL
* my_length_callback, // or NULL
* my_eof_callback, // or NULL
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* or you could do;
*
* \code
* [...]
* FILE *file = fopen("somefile.flac","rb");
* if(file == NULL) do_somthing;
* if(FLAC__stream_decoder_init_FILE(
* decoder,
* file,
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* or just:
*
* \code
* [...]
* if(FLAC__stream_decoder_init_file(
* decoder,
* "somefile.flac",
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* Another small change to the decoder is in how it handles unparseable
* streams. Before, when the decoder found an unparseable stream
* (reserved for when the decoder encounters a stream from a future
* encoder that it can't parse), it changed the state to
* \c FLAC__STREAM_DECODER_UNPARSEABLE_STREAM. Now the decoder instead
* drops sync and calls the error callback with a new error code
* \c FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM. This is
* more robust. If your error callback does not discriminate on the the
* error state, your code does not need to be changed.
*
* The encoder now has a new setting:
* FLAC__stream_encoder_set_apodization(). This is for setting the
* method used to window the data before LPC analysis. You only need to
* add a call to this function if the default is not suitable. There
* are also two new convenience functions that may be useful:
* FLAC__metadata_object_cuesheet_calculate_cddb_id() and
* FLAC__metadata_get_cuesheet().
*
* The \a bytes parameter to FLAC__StreamDecoderReadCallback,
* FLAC__StreamEncoderReadCallback, and FLAC__StreamEncoderWriteCallback
* is now \c size_t instead of \c uint32_t.

*
* \brief
* This module describes porting from FLAC 1.3.4 to FLAC 1.4.0.
*
* \section porting_1_3_4_to_1_4_0_summary Summary
*
* Between FLAC 1.3.4 and FLAC 1.4.0, there have four breaking changes
* - the function get_client_data_from_decoder has been renamed to
* FLAC__get_decoder_client_data
* - some data types in the FLAC__Frame struct have changed
* - all functions resizing metadata blocks now return the object
* untouched if memory allocation fails, whereas previously the
* handling varied and was more or less undefined
* - all functions accepting a filename now take UTF-8 encoded filenames
* on Windows instead of filenames in the current codepage
*
* Furthermore, there have been the following additions
* - the functions FLAC__stream_encoder_set_limit_min_bitrate,
* FLAC__stream_encoder_get_limit_min_bitrate,
* FLAC::encoder::file::set_limit_min_bitrate() and
* FLAC::encoder::file::get_limit_min_bitrate() have been added
* - Added FLAC__STREAM_DECODER_ERROR_STATUS_BAD_METADATA to the
* FLAC__StreamDecoderErrorStatus enum
*
* \section porting_1_3_4_to_1_4_0_breaking Breaking changes
*
* The function \b get_client_data_from_decoder was added in FLAC 1.3.3
* but did not follow the API naming convention and was not properly
* exported. The function is now renamed and properly integrated as
* FLAC__stream_decoder_get_client_data
*
* To accomodate encoding and decoding 32-bit int PCM, some data types
* in the \b FLAC__frame struct were changed. Specifically, warmup
* in both the FLAC__Subframe_Fixed struc and the FLAC__Subframe_LPC
* struct is changed from FLAC__int32 to FLAC__int64. Also, value
* in the FLAC__Subframe_Constant is changed from FLAC__int32 to
* FLAC__int64. Finally, in FLAC__Subframe_Verbatim struct data is
* changes from a FLAC__int32 array to a union containing a FLAC__int32
* array and a FLAC__int64 array. Also, a new member is added,
* data_type, which clarifies whether the FLAC__int32 or FLAC__int64
* array is in use.
*
* Furthermore, the following functions now return the object untouched
* if memory allocation fails, whereas previously the handling varied
* and was more or less undefined
*
* - FLAC__metadata_object_seektable_resize_points
* - FLAC__metadata_object_vorbiscomment_resize_comments
* - FLAC__metadata_object_cuesheet_track_resize_indices
* - FLAC__metadata_object_cuesheet_resize_tracks
*
* The last breaking change is that all API functions taking a filename
* as an argument now, on Windows, must be supplied with that filename
* in the UTF-8 character encoding instead of using the current code
* page. libFLAC internally translates these UTF-8 encoded filenames to
* an appropriate representation to use with _wfopen. On all other
* systems, filename is passed to fopen without any translation, as it
* in libFLAC 1.3.4 and earlier.
*
* \section porting_1_3_4_to_1_4_0_additions Additions
*
* To aid in creating properly streamable FLAC files, a set of functions
* was added to make it possible to enfore a minimum bitrate to files
* created through libFLAC's stream_encoder.h interface. With this
* function enabled the resulting FLAC files have a minimum bitrate of
* 1bit/sample independent of the number of channels, i.e. 48kbit/s for
* 48kHz. This can be beneficial for streaming, as very low bitrates for
* silent sections compressed with 'constant' subframes can result in a
* bitrate of 1kbit/s, creating problems with clients that aren't aware
* of this possibility and buffer too much data.
*
* Finally, FLAC__STREAM_DECODER_ERROR_STATUS_BAD_METADATA was added to
* the FLAC__StreamDecoderErrorStatus enum to signal that the decoder
* encountered unreadable metadata.
*
*/
/** \defgroup flac FLAC C API
*

* describing the components of FLAC streams, and functions for

*
* You should start with the format components as all other modules

*
* \brief
* This module defines the structures for describing I/O callbacks
* to the other FLAC interfaces.
*
* The purpose of the I/O callback functions is to create a common way
* for the metadata interfaces to handle I/O.
*
* Originally the metadata interfaces required filenames as the way of
* specifying FLAC files to operate on. This is problematic in some
* environments so there is an additional option to specify a set of
* callbacks for doing I/O on the FLAC file, instead of the filename.
*
* In addition to the callbacks, a FLAC__IOHandle type is defined as an
* opaque structure for a data source.
*
* The callback function prototypes are similar (but not identical) to the
* stdio functions fread, fwrite, fseek, ftell, feof, and fclose. If you use
* stdio streams to implement the callbacks, you can pass fread, fwrite, and
* fclose anywhere a FLAC__IOCallback_Read, FLAC__IOCallback_Write, or
* FLAC__IOCallback_Close is required, and a FILE* anywhere a FLAC__IOHandle
* is required. \warning You generally CANNOT directly use fseek or ftell
* for FLAC__IOCallback_Seek or FLAC__IOCallback_Tell since on most systems
* these use 32-bit offsets and FLAC requires 64-bit offsets to deal with
* large files. You will have to find an equivalent function (e.g. ftello),
* or write a wrapper. The same is true for feof() since this is usually
* implemented as a macro, not as a function whose address can be taken.

*************************************************************************************
* V110_SDK71, in MSVC 2017 also known as v141_xp, is a platform toolset that is supposed
* to target Windows XP. It turns out however that certain functions provided silently fail
* on Windows XP only, which makes debugging challenging. This only occurs when building with
* /MT. This problem has been reported to Microsoft, but there hasn't been a fix for years. See
* https://web.archive.org/web/20170327195018/https://connect.microsoft.com/VisualStudio/feedback/details/1557168/wstat64-returns-1-on-xp-always
*
* It is known that this problem affects the functions _wstat64 (used by flac_stat i.e.
* stat64_utf8) and _fstat64 (i.e. flac_fstat) and therefore affects both libFLAC in
* several places as well as the flac and metaflac command line tools
*
* As the extent of this problem is unknown and Microsoft seems unwilling to fix it,
* users of libFLAC building with Visual Studio are encouraged to not use the /MT compile
* switch when explicitly targeting Windows XP. When use of /MT is deemed necessary with
* this toolset, be sure to check whether your application works properly on Windows XP.
* It is also possible to build for Windows XP with MinGW instead.

NOTE:
I cannot get the vanilla getopt code to work (i.e. compile only what
is needed and not duplicate symbols found in the standard library)
on all the platforms that FLAC supports. In particular the gating
of code with the ELIDE_CODE #define is not accurate enough on systems
that are POSIX but not glibc. If someone has a patch that works on
GNU/Linux, Darwin, AND Solaris please submit it on the project page:
https://sourceforge.net/p/flac/patches/
In the meantime I have munged the global symbols and removed gates
around code, while at the same time trying to touch the original as
little as possible.

The LONG_OPTIONS argument to share__getopt_long or share__getopt_long_only is a vector
of `struct share__option' terminated by an element containing a name which is
zero.
The field `has_arg' is:
share__no_argument (or 0) if the option does not take an argument,
share__required_argument (or 1) if the option requires an argument,
share__optional_argument (or 2) if the option takes an optional argument.
If the field `flag' is not NULL, it points to a variable that is set
to the value given in the field `val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an `int' to
a compiled-in constant, such as set a value from `share__optarg', set the
option's `flag' field to zero and its `val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero `flag' field, `share__getopt'
returns the contents of the `val' field. */

missing arguments, `share__optopt' is set to the option letter, and '?' is
returned.
The OPTS string is a list of characters which are recognized option
letters, optionally followed by colons, specifying that that letter
takes an argument, to be placed in `share__optarg'.
If a letter in OPTS is followed by two colons, its argument is
optional. This behavior is specific to the GNU `share__getopt'.
The argument `--' causes premature termination of argument
scanning, explicitly telling `share__getopt' that there are no more
options.
If OPTS begins with `--', then non-option arguments are treated as
arguments to the option '\0'. This behavior is specific to the GNU
`share__getopt'. */

# AX_ADD_FORTIFY_SOURCE
#
# DESCRIPTION
#
# Check whether -D_FORTIFY_SOURCE=2 can be added to CPPFLAGS without macro
# redefinition warnings. Some distributions (such as Gentoo Linux) enable
# _FORTIFY_SOURCE globally in their compilers, leading to unnecessary
# warnings in the form of
#
# <command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
# <built-in>: note: this is the location of the previous definition
#
# which is a problem if -Werror is enabled. This macro checks whether
# _FORTIFY_SOURCE is already defined, and if not, adds -D_FORTIFY_SOURCE=2
# to CPPFLAGS.

# SYNOPSIS
#
# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
#
# DESCRIPTION
#
# Check whether the given FLAG works with the current language's compiler
# or gives an error. (Warnings, however, are ignored)
#
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
# success/failure.
#
# If EXTRA-FLAGS is defined, it is added to the current language's default
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
# force the compiler to issue an error when a bad flag is given.
#
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
#
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

#
# SYNOPSIS
#
# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
#
# DESCRIPTION
#
# Check for the presence of an --enable-debug option to configure, with
# the specified default value used when the option is not present. Return
# the value in the variable $ax_enable_debug.
#
# Specifying 'yes' adds '-g -O0' to the compilation flags for all
# languages. Specifying 'info' adds '-g' to the compilation flags.
# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
# the linking flags. Otherwise, nothing is added.
#
# Define the variables listed in the second argument if debug is enabled,
# defaulting to no variables. Defines the variables listed in the third
# argument if debug is disabled, defaulting to NDEBUG. All lists of
# variables should be space-separated.
#
# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
# Should be invoked prior to any AC_PROG_* compiler checks.
#
# IS-RELEASE can be used to change the default to 'no' when making a
# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
# macro, there is no need to pass this parameter.

% flac(1) Version 1.4.3 | Free Lossless Audio Codec conversion tool
# NAME
flac - Free Lossless Audio Codec
# SYNOPSIS
**flac** \[ *OPTIONS* \] \[ *infile.wav* \| *infile.rf64* \|
*infile.aiff* \| *infile.raw* \| *infile.flac* \| *infile.oga* \|
*infile.ogg* \| **-** *...* \]
**flac** \[ **-d** \| **\--decode** \| **-t** \| **\--test** \| **-a** \|
**\--analyze** \] \[ *OPTIONS* \] \[ *infile.flac* \| *infile.oga* \|
*infile.ogg* \| **-** *...* \]
# DESCRIPTION
**flac** is a command-line tool for encoding, decoding, testing and
analyzing FLAC streams.
# GENERAL USAGE
**flac** supports as input RIFF WAVE, Wave64, RF64, AIFF, FLAC or Ogg
FLAC format, or raw interleaved samples. The decoder currently can output
to RIFF WAVE, Wave64, RF64, or AIFF format, or raw interleaved samples.
flac only supports linear PCM samples (in other words, no A-LAW, uLAW,
etc.), and the input must be between 4 and 32 bits per sample.
flac assumes that files ending in ".wav" or that have the RIFF WAVE
header present are WAVE files, files ending in ".w64" or have the Wave64
header present are Wave64 files, files ending in ".rf64" or have the
RF64 header present are RF64 files, files ending in ".aif" or ".aiff" or
have the AIFF header present are AIFF files, files ending in ".flac"
or have the FLAC header present are FLAC files and files ending in ".oga"
or ".ogg" or have the Ogg FLAC header present are Ogg FLAC files.
Other than this, flac makes no assumptions about file extensions, though
the convention is that FLAC files have the extension ".flac"
(or ".fla" on ancient "8.3" file systems like FAT-16).
Before going into the full command-line description, a few other things
help to sort it out:
1. flac encodes by default, so you must use -d to decode
2. the options -0 .. -8 (or --fast and --best) that control the
compression level actually are just synonyms for different groups of
specific encoding options (described later) and you can get the same
effect by using the same options. When specific options are specified
they take priority over the compression level no matter the order
3. flac behaves similarly to gzip in the way it handles input and output
files
4. the order in which options are specified is generally not important
Skip to the examples below for examples of some common tasks.
flac will be invoked one of four ways, depending on whether you are
encoding, decoding, testing, or analyzing. Encoding is the default
invocation, but can be switch to decoding with **-d**, analysis with
**-a** or testing with **-t**. Depending on which way is chosen,
encoding, decoding, analysis or testing options can be used, see section
OPTIONS for details. General options can be used for all.
If only one inputfile is specified, it may be "-" for stdin. When stdin
is used as input, flac will write to stdout. Otherwise flac will perform
the desired operation on each input file to similarly named output files
(meaning for encoding, the extension will be replaced with ".flac", or
appended with ".flac" if the input file has no extension, and for
decoding, the extension will be ".wav" for WAVE output and ".raw" for raw
output). The original file is not deleted unless --delete-input-file is
specified.
If you are encoding/decoding from stdin to a file, you should use the -o
option like so:
flac [options] -o outputfile
flac -d [options] -o outputfile
which are better than:
flac [options] > outputfile
flac -d [options] > outputfile
since the former allows flac to seek backwards to write the STREAMINFO or
RIFF WAVE header contents when necessary.
Also, you can force output data to go to stdout using -c.
To encode or decode files that start with a dash, use -- to signal the
end of options, to keep the filenames themselves from being treated as
options:
flac -V -- -01-filename.wav
The encoding options affect the compression ratio and encoding speed. The
format options are used to tell flac the arrangement of samples if the
input file (or output file when decoding) is a raw file. If it is a RIFF
WAVE, Wave64, RF64, or AIFF file the format options are not needed since
they are read from the file's header.
In test mode, flac acts just like in decode mode, except no output file
is written. Both decode and test modes detect errors in the stream, but
they also detect when the MD5 signature of the decoded audio does not
match the stored MD5 signature, even when the bitstream is valid.
flac can also re-encode FLAC files. In other words, you can specify a
FLAC or Ogg FLAC file as an input to the encoder and it will decoder it
and re-encode it according to the options you specify. It will also
preserve all the metadata unless you override it with other options (e.g.
specifying new tags, seekpoints, cuesheet, padding, etc.).
flac has been tuned so that the default settings yield a good speed vs.
compression tradeoff for many kinds of input. However, if you are looking
to maximize the compression rate or speed, or want to use the full power
of FLAC's metadata system, see the page titled 'About the FLAC Format' on
the FLAC website.
# EXAMPLES
Some common **encoding** tasks using flac:
`flac abc.wav`
: Encode abc.wav to abc.flac using the default compression setting. abc.wav is not deleted.
`flac --delete-input-file abc.wav`
: Like above, except abc.wav is deleted if there were no errors.
`flac --delete-input-file -w abc.wav`
: Like above, except abc.wav is deleted if there were no errors or warnings.
`flac --best abc.wav`
: Encode abc.wav to abc.flac using the highest compression setting.
`flac --verify abc.wav`
: Encode abc.wav to abc.flac and internally decode abc.flac to make sure it matches abc.wav.
`flac -o my.flac abc.wav`
: Encode abc.wav to my.flac.
`flac -T "TITLE=Bohemian Rhapsody" -T "ARTIST=Queen" abc.wav`
: Encode abc.wav and add some tags at the same time to abc.flac.
`flac *.wav`
: Encode all .wav files in the current directory.
`flac abc.aiff`
: Encode abc.aiff to abc.flac.
`flac abc.rf64`
: Encode abc.rf64 to abc.flac.
`flac abc.w64`
: Encode abc.w64 to abc.flac.
`flac abc.flac --force`
: This one's a little tricky: notice that flac is in encode mode by
default (you have to specify -d to decode) so this command actually
recompresses abc.flac back to abc.flac. --force is needed to make
sure you really want to overwrite abc.flac with a new version. Why
would you want to do this? It allows you to recompress an existing
FLAC file with (usually) higher compression options or a newer
version of FLAC and preserve all the metadata like tags too.
Some common **decoding** tasks using flac:
`flac -d abc.flac`
: Decode abc.flac to abc.wav. abc.flac is not deleted. NOTE: Without
-d it means re-encode abc.flac to abc.flac (see above).
`flac -d --force-aiff-format abc.flac`
`flac -d -o abc.aiff abc.flac`
: Two different ways of decoding abc.flac to abc.aiff (AIFF format).
abc.flac is not deleted.
`flac -d --force-rf64-format abc.flac`
`flac -d -o abc.rf64 abc.flac`
: Two different ways of decoding abc.flac to abc.rf64 (RF64 format).
abc.flac is not deleted.
`flac -d --force-wave64-format abc.flac`
`flac -d -o abc.w64 abc.flac`
: Two different ways of decoding abc.flac to abc.w64 (Wave64 format).
abc.flac is not deleted.
`flac -d -F abc.flac`
: Decode abc.flac to abc.wav and don't abort if errors are found
(useful for recovering as much as possible from corrupted files).
# OPTIONS
A summary of options is included below. For a complete description, see
the HTML documentation.
## GENERAL OPTIONS
**-v, \--version**
: Show the flac version number
**-h, \--help**
: Show basic usage and a list of all options
**-H, \--explain**
: Show detailed explanation of usage and all options
**-d, \--decode**
: Decode (the default behavior is to encode)
**-t, \--test**
: Test a flac encoded file (same as -d except no decoded file is written)
**-a, \--analyze**
: Analyze a FLAC encoded file (same as -d except an analysis file is
written)
**-c, \--stdout**
: Write output to stdout
**-s, \--silent**
: Silent mode (do not write runtime encode/decode statistics to stderr)
**\--totally-silent**
: Do not print anything of any kind, including warnings or errors. The
exit code will be the only way to determine successful completion.
**\--no-utf8-convert**
: Do not convert tags from local charset to UTF-8. This is useful for
scripts, and setting tags in situations where the locale is wrong.
This option must appear before any tag options!
**-w, \--warnings-as-errors**
: Treat all warnings as errors (which cause flac to terminate with a
non-zero exit code).
**-f, \--force**
: Force overwriting of output files. By default, flac warns that the
output file already exists and continues to the next file.
**-o** *filename***, \--output-name=***filename*
: Force the output file name (usually flac just changes the extension).
May only be used when encoding a single file. May not be used in
conjunction with \--output-prefix.
**\--output-prefix=***string*
: Prefix each output file name with the given string. This can be
useful for encoding or decoding files to a different directory. Make
sure if your string is a path name that it ends with a trailing \`/'
(slash).
**\--delete-input-file**
: Automatically delete the input file after a successful encode or
decode. If there was an error (including a verify error) the input
file is left intact.
**\--preserve-modtime**
: Output files have their timestamps/permissions set to match those of
their inputs (this is default). Use \--no-preserve-modtime to make
output files have the current time and default permissions.
**\--keep-foreign-metadata**
: If encoding, save WAVE, RF64, or AIFF non-audio chunks in FLAC
metadata. If decoding, restore any saved non-audio chunks from FLAC
metadata when writing the decoded file. Foreign metadata cannot be
transcoded, e.g. WAVE chunks saved in a FLAC file cannot be restored
when decoding to AIFF. Input and output must be regular files (not
stdin or stdout). With this option, FLAC will pick the right output
format on decoding.
**\--keep-foreign-metadata-if-present**
: Like \--keep-foreign-metadata, but without throwing an error if
foreign metadata cannot be found or restored, instead printing a
warning.
**\--skip={***\#***\|***mm:ss.ss***}**
: Skip over the first number of samples of the input. This works for
both encoding and decoding, but not testing. The alternative form
mm:ss.ss can be used to specify minutes, seconds, and fractions of a
second.
**\--until={***\#***\|\[***+***\|***-***\]***mm:ss.ss***}**
: Stop at the given sample number for each input file. This works for
both encoding and decoding, but not testing. The given sample number
is not included in the decoded output. The alternative form mm:ss.ss
can be used to specify minutes, seconds, and fractions of a second.
If a \`+' (plus) sign is at the beginning, the \--until point is
relative to the \--skip point. If a \`-' (minus) sign is at the
beginning, the \--until point is relative to end of the audio.
**\--ogg**
: When encoding, generate Ogg FLAC output instead of native FLAC. Ogg
FLAC streams are FLAC streams wrapped in an Ogg transport layer. The
resulting file should have an '.oga' extension and will still be
decodable by flac. When decoding, force the input to be treated as
Ogg FLAC. This is useful when piping input from stdin or when the
filename does not end in '.oga' or '.ogg'.
**\--serial-number=***\#*
: When used with \--ogg, specifies the serial number to use for the
first Ogg FLAC stream, which is then incremented for each additional
stream. When encoding and no serial number is given, flac uses a
random number for the first stream, then increments it for each
additional stream. When decoding and no number is given, flac uses
the serial number of the first page.
## ANALYSIS OPTIONS
**\--residual-text**
: Includes the residual signal in the analysis file. This will make the
file very big, much larger than even the decoded file.
**\--residual-gnuplot**
: Generates a gnuplot file for every subframe; each file will contain
the residual distribution of the subframe. This will create a lot of
files.
## DECODING OPTIONS
**\--cue=\[***\#.#***\]\[-\[***\#.#***\]\]**
: Set the beginning and ending cuepoints to decode. The optional first
\#.# is the track and index point at which decoding will start; the
default is the beginning of the stream. The optional second \#.# is
the track and index point at which decoding will end; the default is
the end of the stream. If the cuepoint does not exist, the closest
one before it (for the start point) or after it (for the end point)
will be used. If those don't exist, the start of the stream (for the
start point) or end of the stream (for the end point) will be used.
The cuepoints are merely translated into sample numbers then used as
\--skip and \--until. A CD track can always be cued by, for example,
\--cue=9.1-10.1 for track 9, even if the CD has no 10th track.
**-F, \--decode-through-errors**
: By default flac stops decoding with an error and removes the
partially decoded file if it encounters a bitstream error. With -F,
errors are still printed but flac will continue decoding to
completion. Note that errors may cause the decoded audio to be
missing some samples or have silent sections.
**\--apply-replaygain-which-is-not-lossless\[=\<specification\>\]**
: Applies ReplayGain values while decoding. **WARNING: THIS IS NOT
LOSSLESS. DECODED AUDIO WILL NOT BE IDENTICAL TO THE ORIGINAL WITH
THIS OPTION.** This option is useful for example in transcoding
media servers, where the client does not support ReplayGain. For
details on the use of this option, see the section **ReplayGain
application specification**.
## ENCODING OPTIONS
**-V, \--verify**
: Verify a correct encoding by decoding the output in parallel and
comparing to the original
**\--lax**
: Allow encoder to generate non-Subset files. The resulting FLAC file
may not be streamable or might have trouble being played in all
players (especially hardware devices), so you should only use this
option in combination with custom encoding options meant for
archival.
**\--replay-gain**
: Calculate ReplayGain values and store them as FLAC tags, similar to
vorbisgain. Title gains/peaks will be computed for each input file,
and an album gain/peak will be computed for all files. All input
files must have the same resolution, sample rate, and number of
channels. Only mono and stereo files are allowed, and the sample
rate must be 8, 11.025, 12, 16, 18.9, 22.05, 24, 28, 32, 36, 37.8,
44.1, 48, 56, 64, 72, 75.6, 88.2, 96, 112, 128, 144, 151.2, 176.4,
192, 224, 256, 288, 302.4, 352.8, 384, 448, 512, 576, or 604.8 kHz.
Also note that this option may leave a few extra bytes in a PADDING
block as the exact size of the tags is not known until all files
are processed. Note that this option cannot be used when encoding
to standard output (stdout).
**\--cuesheet=***filename*
: Import the given cuesheet file and store it in a CUESHEET metadata
block. This option may only be used when encoding a single file. A
seekpoint will be added for each index point in the cuesheet to the
SEEKTABLE unless \--no-cued-seekpoints is specified.
**\--picture={***FILENAME***\|***SPECIFICATION***}**
: Import a picture and store it in a PICTURE metadata block. More than
one \--picture option can be specified. Either a filename for the
picture file or a more complete specification form can be used. The
SPECIFICATION is a string whose parts are separated by \| (pipe)
characters. Some parts may be left empty to invoke default values.
FILENAME is just shorthand for "\|\|\|\|FILENAME". For the format of
SPECIFICATION, see the section **picture specification**.
**\--ignore-chunk-sizes**
: When encoding to flac, ignore the file size headers in WAV and AIFF
files to attempt to work around problems with over-sized or malformed
files. WAV and AIFF files both have an unsigned 32 bit numbers in
the file header which specifes the length of audio data. Since this
number is unsigned 32 bits, that limits the size of a valid file to
being just over 4 Gigabytes. Files larger than this are mal-formed,
but should be read correctly using this option.
**-S {***\#***\|***X***\|***\#x***\|***\#s***}, \--seekpoint={***\#***\|***X***\|***\#x***\|***\#s***}**
: Include a point or points in a SEEKTABLE. Using \#, a seek point at
that sample number is added. Using X, a placeholder point is added at
the end of a the table. Using \#x, \# evenly spaced seek points will
be added, the first being at sample 0. Using \#s, a seekpoint will be
added every \# seconds (# does not have to be a whole number; it can
be, for example, 9.5, meaning a seekpoint every 9.5 seconds). You may
use many -S options; the resulting SEEKTABLE will be the unique-ified
union of all such values. With no -S options, flac defaults to
'-S 10s'. Use \--no-seektable for no SEEKTABLE. Note: '-S \#x' and
'-S \#s' will not work if the encoder can't determine the input size
before starting. Note: if you use '-S \#' and \# is \>= samples in
the input, there will be either no seek point entered (if the input
size is determinable before encoding starts) or a placeholder point
(if input size is not determinable).
**-P** *\#***, \--padding=***\#*
: Tell the encoder to write a PADDING metadata block of the given
length (in bytes) after the STREAMINFO block. This is useful if you
plan to tag the file later with an APPLICATION block; instead of
having to rewrite the entire file later just to insert your block,
you can write directly over the PADDING block. Note that the total
length of the PADDING block will be 4 bytes longer than the length
given because of the 4 metadata block header bytes. You can force no
PADDING block at all to be written with \--no-padding. The encoder
writes a PADDING block of 8192 bytes by default (or 65536 bytes if
the input audio stream is more that 20 minutes long).
**-T** *FIELD=VALUE***, \--tag=***FIELD=VALUE*
: Add a FLAC tag. The comment must adhere to the Vorbis comment spec;
i.e. the FIELD must contain only legal characters, terminated by an
'equals' sign. Make sure to quote the comment if necessary. This
option may appear more than once to add several comments. NOTE: all
tags will be added to all encoded files.
**\--tag-from-file=***FIELD=FILENAME*
: Like \--tag, except FILENAME is a file whose contents will be read
verbatim to set the tag value. The contents will be converted to
UTF-8 from the local charset. This can be used to store a cuesheet
in a tag (e.g. \--tag-from-file="CUESHEET=image.cue"). Do not try to
store binary data in tag fields! Use APPLICATION blocks for that.
**-b** *\#***, \--blocksize=***\#*
: Specify the blocksize in samples. The default is 1152 for -l 0,
else 4096. For subset streams this must be \<= 4608 if the samplerate
\<= 48kHz, for subset streams with higher samplerates it must be \<=
16384.
**-m, \--mid-side**
: Try mid-side coding for each frame (stereo input only)
**-M, \--adaptive-mid-side**
: Adaptive mid-side coding for all frames (stereo input only)
**-0..-8, \--compression-level-0..\--compression-level-8**
: Fastest compression..highest compression (default is -5). These are
synonyms for other options:
**-0, \--compression-level-0**
: Synonymous with -l 0 -b 1152 -r 3 \--no-mid-side
**-1, \--compression-level-1**
: Synonymous with -l 0 -b 1152 -M -r 3
**-2, \--compression-level-2**
: Synonymous with -l 0 -b 1152 -m -r 3
**-3, \--compression-level-3**
: Synonymous with -l 6 -b 4096 -r 4 \--no-mid-side
**-4, \--compression-level-4**
: Synonymous with -l 8 -b 4096 -M -r 4
**-5, \--compression-level-5**
: Synonymous with -l 8 -b 4096 -m -r 5
**-6, \--compression-level-6**
: Synonymous with -l 8 -b 4096 -m -r 6 -A subdivide_tukey(2)
**-7, \--compression-level-7**
: Synonymous with -l 12 -b 4096 -m -r 6 -A subdivide_tukey(2)
**-8, \--compression-level-8**
: Synonymous with -l 12 -b 4096 -m -r 6 -A subdivide_tukey(3)
**\--fast**
: Fastest compression. Currently synonymous with -0.
**\--best**
: Highest compression. Currently synonymous with -8.
**-e, \--exhaustive-model-search**
: Do exhaustive model search (expensive!)
**-A** *function***, \--apodization=***function*
: Window audio data with given the apodization function. See section
**Apodization functions** for details.
**-l** *\#***, \--max-lpc-order=***\#*
: Specifies the maximum LPC order. This number must be \<= 32. For
subset streams, it must be \<=12 if the sample rate is \<=48kHz. If
0, the encoder will not attempt generic linear prediction, and use
only fixed predictors. Using fixed predictors is faster but usually
results in files being 5-10% larger.
**-p, \--qlp-coeff-precision-search**
: Do exhaustive search of LP coefficient quantization (expensive!).
Overrides -q; does nothing if using -l 0
**-q** *\#***, \--qlp-coeff-precision=***\#*
: Precision of the quantized linear-predictor coefficients, 0 =\> let
encoder decide (min is 5, default is 0)
**-r \[***\#***,\]***\#***, \--rice-partition-order=\[***\#***,\]***\#*
: Set the \[min,\]max residual partition order (0..15). min defaults to
0 if unspecified. Default is -r 5.
## FORMAT OPTIONS
**\--endian={***big***\|***little***}**
: Set the byte order for samples
**\--channels=***\#*
: Set number of channels.
**\--bps=***\#*
: Set bits per sample.
**\--sample-rate=***\#*
: Set sample rate (in Hz).
**\--sign={***signed***\|***unsigned***}**
: Set the sign of samples.
**\--input-size=***\#*
: Specify the size of the raw input in bytes. If you are encoding raw
samples from stdin, you must set this option in order to be able to
use \--skip, \--until, \--cuesheet, or other options that need to
know the size of the input beforehand. If the size given is greater
than what is found in the input stream, the encoder will complain
about an unexpected end-of-file. If the size given is less, samples
will be truncated.
**\--force-raw-format**
: Force input (when encoding) or output (when decoding) to be treated
as raw samples (even if filename ends in *.wav*).
**\--force-aiff-format**
**\--force-rf64-format**
**\--force-wave64-format**
: Force the decoder to output AIFF/RF64/WAVE64 format respectively.
This option is not needed if the output filename (as set by -o)
ends with *.aif* or *.aiff*, *.rf64* and *.w64* respectively. Also,
this option has no effect when encoding since input is
auto-detected. When none of these options nor
--keep-foreign-metadata are given and no output filename is set,
the output format is WAV by default.
**\--force-legacy-wave-format**
**\--force-extensible-wave-format**
: Instruct the decoder to output a WAVE file with WAVE_FORMAT_PCM and
WAVE_FORMAT_EXTENSIBLE respectively. If none of these options nor
--keep-foreign-metadata are given, FLAC outputs WAVE_FORMAT_PCM
for mono or stereo with a bit depth of 8 or 16 bits, and
WAVE_FORMAT_EXTENSIBLE for all other audio formats.
**\--force-aiff-c-none-format**
**\--force-aiff-c-sowt-format**
: Instruct the decoder to output an AIFF-C file with format NONE and
sowt respectively.
## NEGATIVE OPTIONS
**\--no-adaptive-mid-side**
**\--no-cued-seekpoints**
**\--no-decode-through-errors**
**\--no-delete-input-file**
**\--no-preserve-modtime**
**\--no-keep-foreign-metadata**
**\--no-exhaustive-model-search**
**\--no-force**
**\--no-lax**
**\--no-mid-side**
**\--no-ogg**
**\--no-padding**
**\--no-qlp-coeff-prec-search**
**\--no-replay-gain**
**\--no-residual-gnuplot**
**\--no-residual-text**
**\--no-seektable**
**\--no-silent**
**\--no-verify**
**\--no-warnings-as-errors**
These flags can be used to invert the sense of the corresponding normal
option.
## ReplayGain application specification
The option \--apply-replaygain-which-is-not-lossless\[=\<specification\>\]**
applies ReplayGain values while decoding. **WARNING: THIS IS NOT
LOSSLESS. DECODED AUDIO WILL NOT BE IDENTICAL TO THE ORIGINAL WITH THIS
OPTION.** This option is useful for example in transcoding media servers,
where the client does not support ReplayGain.
The equals sign and \<specification\> is optional. If omitted, the
default specification is 0aLn1.
The \<specification\> is a shorthand notation for describing how to apply
ReplayGain. All components are optional but order is important. '\[\]'
means 'optional'. '\|' means 'or'. '{}' means required. The format is:
\[\<preamp\>\]\[a\|t\]\[l\|L\]\[n{0\|1\|2\|3}\]
In which the following parameters are used:
- **preamp**: A floating point number in dB. This is added to the
existing gain value.
- **a\|t**: Specify 'a' to use the album gain, or 't' to use the track
gain. If tags for the preferred kind (album/track) do not exist but
tags for the other (track/album) do, those will be used instead.
- **l\|L**: Specify 'l' to peak-limit the output, so that the
ReplayGain peak value is full-scale. Specify 'L' to use a 6dB hard
limiter that kicks in when the signal approaches full-scale.
- **n{0\|1\|2\|3}**: Specify the amount of noise shaping. ReplayGain
synthesis happens in floating point; the result is dithered before
converting back to integer. This quantization adds noise. Noise
shaping tries to move the noise where you won't hear it as much.
0 means no noise shaping, 1 means 'low', 2 means 'medium', 3 means
'high'.
For example, the default of 0aLn1 means 0dB preamp, use album gain, 6dB
hard limit, low noise shaping. \--apply-replaygain-which-is-not-lossless=3
means 3dB preamp, use album gain, no limiting, no noise shaping.
flac uses the ReplayGain tags for the calculation. If a stream does
not have the required tags or they can't be parsed, decoding will
continue with a warning, and no ReplayGain is applied to that stream.
## Picture specification
This described the specification used for the **\--picture** option.
\[TYPE\]\|\[MIME-TYPE\]\|\[DESCRIPTION\]\|\[WIDTHxHEIGHTxDEPTH\[/COLORS\]\]\|FILE
TYPE is optional; it is a number from one of:
0. Other
1. 32x32 pixels 'file icon' (PNG only)
2. Other file icon
3. Cover (front)
4. Cover (back)
5. Leaflet page
6. Media (e.g. label side of CD)
7. Lead artist/lead performer/soloist
8. Artist/performer
9. Conductor
10. Band/Orchestra
11. Composer
12. Lyricist/text writer
13. Recording Location
14. During recording
15. During performance
16. Movie/video screen capture
17. A bright coloured fish
18. Illustration
19. Band/artist logotype
20. Publisher/Studio logotype
The default is 3 (front cover). There may only be one picture each of
type 1 and 2 in a file.
MIME-TYPE is optional; if left blank, it will be detected from the file.
For best compatibility with players, use pictures with MIME type
image/jpeg or image/png. The MIME type can also be \--\> to mean that
FILE is actually a URL to an image, though this use is discouraged.
DESCRIPTION is optional; the default is an empty string.
The next part specifies the resolution and color information. If the
MIME-TYPE is image/jpeg, image/png, or image/gif, you can usually leave
this empty and they can be detected from the file. Otherwise, you must
specify the width in pixels, height in pixels, and color depth in
bits-per-pixel. If the image has indexed colors you should also specify
the number of colors used. When manually specified, it is not checked
against the file for accuracy.
FILE is the path to the picture file to be imported, or the URL if MIME
type is \--\>
For example, "\|image/jpeg\|\|\|../cover.jpg" will embed the JPEG file
at ../cover.jpg, defaulting to type 3 (front cover) and an empty
description. The resolution and color info will be retrieved from the
file itself.
The specification
"4\|\--\>\|CD\|320x300x24/173\|http://blah.blah/backcover.tiff" will
embed the given URL, with type 4 (back cover), description "CD", and a
manually specified resolution of 320x300, 24 bits-per-pixel, and 173
colors. The file at the URL will not be fetched; the URL itself is
stored in the PICTURE metadata block.
## Apodization functions
To improve LPC analysis, audio data is windowed . The window can be
selected with one or more **-A** options. Possible functions are:
bartlett, bartlett_hann, blackman, blackman_harris_4term_92db,
connes, flattop, gauss(STDDEV), hamming, hann, kaiser_bessel, nuttall,
rectangle, triangle, tukey(P), partial_tukey(n\[/ov\[/P\]\]),
punchout_tukey(n\[/ov\[/P\]\]), subdivide_tukey(n\[/P\]) welch.
- For gauss(STDDEV), STDDEV is the standard deviation (0\<STDDEV\<=0.5).
- For tukey(P), P specifies the fraction of the window that is tapered
(0\<=P\<=1; P=0 corresponds to "rectangle" and P=1 corresponds to
"hann").
- For partial_tukey(n) and punchout_tukey(n), n apodization functions are
added that span different parts of each block. Values of 2 to 6 seem to
yield sane results. If necessary, an overlap can be specified, as can be
the taper parameter, for example partial_tukey(2/0.2) or
partial_tukey(2/0.2/0.5). ov should be smaller than 1 and can be
negative. The use of this is that different parts of a block are ignored
as the might contain transients which are hard to predict anyway. The
encoder will try each different added apodization (each covering a
different part of the block) to see which resulting predictor results in
the smallest representation.
- subdivide_tukey(n) is a more efficient reimplementation of partial_tukey
and punchout_tukey taken together, recycling as much data as possible. It
combines all possible non-redundant partial_tukey(n) and punchout_tukey(n)
up to the n specified. Specifying subdivide_tukey(3) is equivalent to
specifying tukey, partial_tukey(2), partial_tukey(3) and punchout_tukey(3),
specifying subdivide_tukey(5) equivalently adds partial_tukey(4),
punchout_tukey(4), partial_tukey(5) and punchout_tukey(5). To be able to
reuse data as much as possible, the tukey taper is taken equal for all
windows, and the P specified is applied for the smallest used window.
In other words, subdivide_tukey(2/0.5) results in a taper equal to that
of tukey(0.25) and subdivide_tukey(5) in a taper equal to that of
tukey(0.1). The default P for subdivide_tukey when none is specified is
0.5.
Note that P, STDDEV and ov are locale specific, so a comma as
decimal separator might be required instead of a dot. Use scientific
notation for a locale-independent specification, for example
tukey(5e-1) instead of tukey(0.5) or tukey(0,5).
More than one -A option (up to 32) may be used. Any function that is
specified erroneously is silently dropped. The encoder chooses suitable
defaults in the absence of any -A options; any -A option specified
replaces the default(s).
When more than one function is specified, then for every subframe the
encoder will try each of them separately and choose the window that
results in the smallest compressed subframe. Multiple functions can
greatly increase the encoding time.

% metaflac(1) Version 1.4.3 | Free Lossless Audio Codec metadata tool
# NAME
metaflac - program to list, add, remove, or edit metadata in one or more
FLAC files.
# SYNOPSIS
**metaflac** \[ *options* \] \[ *operations* \] *FLACfile ...*
# DESCRIPTION
Use **metaflac** to list, add, remove, or edit metadata in one or more
FLAC files. You may perform one major operation, or many shorthand
operations at a time.
# GENERAL USAGE
metaflac is the command-line .flac file metadata editor. You can use it
to list the contents of metadata blocks, edit, delete or insert blocks,
and manage padding.
metaflac takes a set of "options" (though some are not optional) and a
set of FLAC files to operate on. There are three kinds of "options":
- Major operations, which specify a mode of operation like listing
blocks, removing blocks, etc. These will have sub-operations describing
exactly what is to be done.
- Shorthand operations, which are convenient synonyms for major
operations. For example, there is a shorthand operation
--show-sample-rate that shows just the sample rate field from the
STREAMINFO metadata block.
- Global options, which affect all the operations.
All of these are described in the tables below. At least one shorthand
or major operation must be supplied. You can use multiple shorthand
operations to do more than one thing to a file or set of files. Most of
the common things to do to metadata have shorthand operations. As an
example, here is how to show the MD5 signatures for a set of three FLAC
files:
`metaflac --show-md5sum file1.flac file2.flac file3.flac`
Another example; this removes all DESCRIPTION and COMMENT tags in a set
of FLAC files, and uses the --preserve-modtime global option to keep the
FLAC file modification times the same (usually when files are edited the
modification time is set to the current time):
`metaflac --preserve-modtime --remove-tag=DESCRIPTION --remove-tag=COMMENT file1.flac file2.flac file3.flac`
# OPTIONS
**\--preserve-modtime**
: Preserve the original modification time in spite of edits.
**\--with-filename**
: Prefix each output line with the FLAC file name (the default if more
than one FLAC file is specified). This option has no effect for
options exporting to a file, like --export-tags-to.
**\--no-filename**
: Do not prefix each output line with the FLAC file name (the default
if only one FLAC file is specified).
**\--no-utf8-convert**
: Do not convert tags from UTF-8 to local charset, or vice versa. This
is useful for scripts, and setting tags in situations where the
locale is wrong.
**\--dont-use-padding**
: By default metaflac tries to use padding where possible to avoid
rewriting the entire file if the metadata size changes. Use this
option to tell metaflac to not take advantage of padding this way.
# SHORTHAND OPERATIONS
**\--show-md5sum**
: Show the MD5 signature from the STREAMINFO block.
**\--show-min-blocksize**
: Show the minimum block size from the STREAMINFO block.
**\--show-max-blocksize**
: Show the maximum block size from the STREAMINFO block.
**\--show-min-framesize**
: Show the minimum frame size from the STREAMINFO block.
**\--show-max-framesize**
: Show the maximum frame size from the STREAMINFO block.
**\--show-sample-rate**
: Show the sample rate from the STREAMINFO block.
**\--show-channels**
: Show the number of channels from the STREAMINFO block.
**\--show-bps**
: Show the \# of bits per sample from the STREAMINFO block.
**\--show-total-samples**
: Show the total \# of samples from the STREAMINFO block.
**\--show-vendor-tag**
: Show the vendor string from the VORBIS_COMMENT block.
**\--show-tag=name**
: Show all tags where the field name matches 'name'.
**\--show-all-tags**
: Show all tags. This is an alias for --export-tags-to=-.
**\--remove-tag=name**
: Remove all tags whose field name is 'name'.
**\--remove-first-tag=name**
: Remove first tag whose field name is 'name'.
**\--remove-all-tags**
: Remove all tags, leaving only the vendor string.
**\--remove-all-tags-except=NAME1\[=NAME2\[=...\]\]**
: Remove all tags, except the vendor string and the tag names
specified. Tag names must be separated by an = character.
**\--set-tag=field**
: Add a tag. The field must comply with the Vorbis comment spec, of the
form "NAME=VALUE". If there is currently no tag block, one will be
created.
**\--set-tag-from-file=field**
: Like \--set-tag, except the VALUE is a filename whose contents will
be read verbatim to set the tag value. Unless \--no-utf8-convert is
specified, the contents will be converted to UTF-8 from the local
charset. This can be used to store a cuesheet in a tag (e.g.
\--set-tag-from-file="CUESHEET=image.cue"). Do not try to store
binary data in tag fields! Use APPLICATION blocks for that.
**\--import-tags-from=file**
: Import tags from a file. Use '-' for stdin. Each line should be of
the form NAME=VALUE. Multi-line comments are currently not supported.
Specify \--remove-all-tags and/or \--no-utf8-convert before
\--import-tags-from if necessary. If FILE is '-' (stdin), only one
FLAC file may be specified.
**\--export-tags-to=file**
: Export tags to a file. Use '-' for stdout. Each line will be of the
form NAME=VALUE. Specify \--no-utf8-convert if necessary.
**\--import-cuesheet-from=file**
: Import a cuesheet from a file. Use '-' for stdin. Only one FLAC file
may be specified. A seekpoint will be added for each index point in
the cuesheet to the SEEKTABLE unless \--no-cued-seekpoints is
specified.
**\--export-cuesheet-to=file**
: Export CUESHEET block to a cuesheet file, suitable for use by CD
authoring software. Use '-' for stdout. Only one FLAC file may be
specified on the command line.
**\--import-picture-from={***FILENAME***\|***SPECIFICATION***}**
: Import a picture and store it in a PICTURE metadata block. More than
one \--import-picture-from command can be specified. Either a filename
for the picture file or a more complete specification form can be
used. The SPECIFICATION is a string whose parts are separated by \|
(pipe) characters. Some parts may be left empty to invoke default
values. FILENAME is just shorthand for "\|\|\|\|FILENAME". For
details on the specification, see the section **Picture
specification** in the **flac(1)** man page.
**\--export-picture-to=file**
: Export PICTURE block to a file. Use '-' for stdout. Only one FLAC
file may be specified on the command line. The first PICTURE block
will be exported unless \--export-picture-to is preceded by a
\--block-number=# option to specify the exact metadata block to
extract. Note that the block number is the one shown by \--list.
**\--add-replay-gain**
: Calculates the title and album gains/peaks of the given FLAC files as
if all the files were part of one album, then stores them as FLAC
tags. The tags are the same as those used by vorbisgain. Existing
ReplayGain tags will be replaced. If only one FLAC file is given,
the album and title gains will be the same. Since this operation
requires two passes, it is always executed last, after all other
operations have been completed and written to disk. All FLAC files
specified must have the same resolution, sample rate, and number of
channels. Only mono and stereo files are allowed, and the sample
rate must be 8, 11.025, 12, 16, 18.9, 22.05, 24, 28, 32, 36, 37.8,
44.1, 48, 56, 64, 72, 75.6, 88.2, 96, 112, 128, 144, 151.2, 176.4,
192, 224, 256, 288, 302.4, 352.8, 384, 448, 512, 576, or 604.8 kHz.
**\--scan-replay-gain**
: Like \--add-replay-gain, but only analyzes the files rather than
writing them to the tags.
**\--remove-replay-gain**
: Removes the ReplayGain tags.
**\--add-seekpoint={***\#***\|***X***\|***\#x***\|***\#s***}**
: Add seek points to a SEEKTABLE block. Using \#, a seek point at that
sample number is added. Using X, a placeholder point is added at the
end of a the table. Using \#x, \# evenly spaced seek points will be
added, the first being at sample 0. Using \#s, a seekpoint will be
added every \# seconds (# does not have to be a whole number; it can
be, for example, 9.5, meaning a seekpoint every 9.5 seconds). If no
SEEKTABLE block exists, one will be created. If one already exists,
points will be added to the existing table, and any duplicates will
be turned into placeholder points. You may use many \--add-seekpoint
options; the resulting SEEKTABLE will be the unique-ified union of
all such values. Example: \--add-seekpoint=100x \--add-seekpoint=3.5s
will add 100 evenly spaced seekpoints and a seekpoint every 3.5
seconds.
**\--add-padding=length**
: Add a padding block of the given length (in bytes). The overall
length of the new block will be 4 + length; the extra 4 bytes is for
the metadata block header.
# MAJOR OPERATIONS
**\--list**
: List the contents of one or more metadata blocks to stdout. By
default, all metadata blocks are listed in text format. Use the
options **\--block-number**, **\--block-type** or
**\--except-block-type** to change this behavior.
**\--remove**
: Remove one or more metadata blocks from the metadata. Use the options
**\--block-number**, **\--block-type** or **\--except-block-type**
to specify which blocks should be removed. Note that if both
\--block-number and \--[except-]block-type are specified, the result
is the logical AND of both arguments. Unless \--dont-use-padding
is specified, the blocks will be replaced with padding. You may not
remove the STREAMINFO block.
**\--block-number=#\[,#\[...\]\]**
: An optional comma-separated list of block numbers to display. The
first block, the STREAMINFO block, is block 0.
**\--block-type=type\[,type\[...\]\]**
**\--except-block-type=type\[,type\[...\]\]**
: An optional comma-separated list of block types to be included or
ignored with this option. Use only one of \--block-type or
\--except-block-type. The valid block types are: STREAMINFO, PADDING,
APPLICATION, SEEKTABLE, VORBIS_COMMENT, PICTURE. You may narrow down
the types of APPLICATION blocks selected by appending APPLICATION
with a colon and the ID of the APPLICATION block in either ASCII
or hexadecimal representation. E.g. APPLICATION:abcd for the
APPLICATION block(s) whose textual representation of the 4-byte ID
is "abcd" or APPLICATION:0xXXXXXXXX for the APPLICATION block(s)
whose hexadecimal big- endian representation of the 4-byte ID
is "0xXXXXXXXX". For the example "abcd" above the hexadecimal
equivalalent is 0x61626364
**\--application-data-format=hexdump\|text**
: If the application block you are displaying contains binary data but
your \--data-format=text, you can display a hex dump of the
application data contents instead using
\--application-data-format=hexdump.
**\--data-format=binary\|binary-headerless\|text**
: For use with --list. By default a human-readable text
representation of the data is isplayed. You may specify
--data-format=binary to dump the raw binary form of each metadata
block. Specify --data-format=binary-headerless to omit output of
metadata block headers, including the id of APPLICATION metadata
blocks.
**\--append**
: Insert a metadata block from a file. This must be a binary block as
exported with --list --data-format=binary. The insertion point is
defined with --block-number=#. The new block will be added after the
given block number. This prevents the illegal insertion of a block
before the first STREAMINFO block. You may not --append another
STREAMINFO block. It is possible to copy a metadata block from one
file to another with this option. For example use
`metaflac --list --data-format=binary --block-number=6 file.flac > block`
to export the block, and then import it with
`metaflac --append anotherfile.flac < block`
**\--remove-all**
: Remove all metadata blocks (except the STREAMINFO block) from the
metadata. Unless \--dont-use-padding is specified, the blocks will be
replaced with padding.
**\--merge-padding**
: Merge adjacent PADDING blocks into single blocks.
**\--sort-padding**
: Move all PADDING blocks to the end of the metadata and merge them
into a single block.
