Can I use LAME in my commercial program? Yes, you can, under the restrictions of the LGPL. The easiest way to do this is to: 1. Link to LAME as separate library (libmp3lame.a on unix or lame_enc.dll on windows) 2. Fully acknowledge that you are using LAME, and give a link to our web site, www.mp3dev.org 3. If you make modifications to LAME, you *must* release these modifications back to the LAME project, under the LGPL. *** IMPORTANT NOTE *** The decoding functions provided in LAME use a version of the mpglib decoding engine which is under the GPL. They may not be used by any program not released under the GPL unless you obtain such permission from the MPG123 project (www.mpg123.de). (yes, we know MPG123 is currently under the LGPL, but we use an older version that was released under the former license and, until someone tweaks the current MPG123 to suit some of LAME's specific needs, it'll continue being licensed under the GPL)
