- FLAC is an open source project and we are happy to enlist the help of anyone who wants to contribute. You can do this to a limited extent through the <A HREF="http://sourceforge.net/mail/?group_id=13478">mailing list</A> but if you have major changes to make to the code it's best to <A HREF="http://sourceforge.net/project/memberlist.php?group_id=13478">sign up as a developer</A>. In either case, make sure to check out the <A HREF="goals.html">FLAC goals</A> first; there are some thing the we <B>don't</B> want added to FLAC, like copy protection and lossy compression.

+ <div class="box_body">
+ 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.<br />
+ <br />
+ <b>Goals</b>
+ <ul>
+ <li>
+ FLAC should be and stay an open format with an open-source reference implementation.
+ </li>
+ <li>
+ FLAC should be lossless. This seems obvious but lossy compression seems to creep into every audio codec. This goal also means that <span class="commandname">flac</span> should stay archival quality and be truly lossless for all input. Testing of releases should be thorough.
+ </li>
+ <li>
+ FLAC should yield respectable compression, on par or better than other lossless codecs.
+ </li>
+ <li>
+ FLAC should allow at least realtime decoding on even modest hardware.
+ </li>
+ <li>
+ FLAC should support fast sample-accurate seeking.
+ </li>
+ <li>
+ FLAC should allow gapless playback of consecutive streams. This follows from the lossless goal.
+ </li>
+ <li>
+ 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.
+ </li>
+ </ul>
+ <b>Anti-goals</b><br />
+ <ul>
+ <li>
+ Lossy compression. There are already many suitable lossy formats (<a href="http://www.xiph.org/ogg/vorbis/index.html">Ogg Vorbis</a>, <a href="http://www.mp3-tech.org/">MP3</a>, etc.).
+ </li>
+ <li>
+ 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.
