Thanks for considering contributing to the FLAC project!
Contributing to FLAC is possible in many ways. Among them are
- Reporting bugs or other issues at https://github.com/xiph/flac/issues
- Submitting patches at https://github.com/xiph/flac/pulls
- Testing FLAC playing devices and software at
https://wiki.hydrogenaud.io/index.php?title=FLAC_decoder_testbench
General communication not specific to issues is generally done through
the FLAC mailing lists:
- For user questions and discussions:
https://lists.xiph.org/mailman/listinfo/flac
- For developer questions and discussions:
https://lists.xiph.org/mailman/listinfo/flac-dev
## Goals
Since FLAC is an open-source project, it's important to have a set of
goals that everyone works to. They may change slightly from time to time
but they're a good guideline. Changes should be in line with the goals
and should not attempt to embrace any of the anti-goals.
**Goals**
- FLAC should be and stay an open format with an open-source reference
implementation.
- FLAC should be lossless. This seems obvious but lossy compression
seems to creep into every audio codec. This goal also means that flac
should stay archival quality and be truly lossless for all input.
Testing of releases should be thorough.
- FLAC should yield respectable compression, on par or better than other
lossless codecs.
- FLAC should allow at least realtime decoding on even modest hardware.
- FLAC should support fast sample-accurate seeking.
- FLAC should allow gapless playback of consecutive streams. This follows from the lossless goal.
- The FLAC project owes a lot to the many people who have advanced the
audio compression field so freely, and aims also to contribute through
the open-source development of new ideas.
**Anti-goals**
- Lossy compression. There are already many suitable lossy formats (Ogg
Vorbis, MP3, etc.).
- Copy prevention, DRM, etc. There is no intention to add any copy
prevention methods. Of course, we can't stop someone from encrypting a
FLAC stream in another container (e.g. the way Apple encrypts AAC in
MP4 with FairPlay), that is the choice of the user.
## Contributing patches
Contributions to FLAC should be licensed with the same license as the
part of the FLAC project the contribution belongs to. These are
- libFLAC and libFLAC++ are licensed under Xiph.org's
BSD-like license (see COPYING.Xiph), so contributions to these
libraries should also be licensed under this license, otherwise they
cannot be accepted
- the flac and metaflac command line programs are licensed under GPLv2,
see COPYING.GPL
- the helper libraries for flac and metaflac (which are in src/share)
are licensed under varying licenses, see the license preamble for each
file to see how they are licensed
Patches can be contributed through GitHub as a Pull Request.
Alternatively you can supply patches through the mailing list.
## Code style
FLAC does have its own peculiar coding style that does not seem to fit
general categories. You can use `git clang-format` to have your patch
auto-formatted similar to the rest of the code.

specially designated Free Software Foundation software, and to any
other libraries whose authors decide to use it. You can use it for

When we speak of free software, we are referring to freedom, not

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 a program 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
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.
Our method of protecting your rights has two steps: (1) copyright

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.
Also, for each distributor's protection, we want to make certain
that everyone understands that there is no warranty for this free
library. If the library is modified by someone else and passed on, we
want its recipients to know that what they have is not the original
version, so that any problems introduced by others will not reflect on
the original authors' reputations.
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, any free program is threatened constantly by software
patents. We wish to avoid the danger that companies distributing free
software will individually obtain patent licenses, thus in effect
transforming the program into proprietary software. To prevent this,
we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
Because of this blurred distinction, using the ordinary General
Public License for libraries did not effectively promote software
sharing, because most developers did not use the libraries. We
concluded that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the
users of those programs of all benefit from the free status of the
libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while
preserving your freedom as a user of such programs to change the free
libraries that are incorporated in them. (We have not seen how to achieve
this as regards changes in header files, but we have achieved it as regards
changes in the actual functions of the Library.) The hope is that this
will lead to faster development of free libraries.
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, while the latter only
works together with the library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.

be combined with the library in order to run.
