If you determine that distribution of LAME requires a patent license, + and you obtain a patent license, you may distribute LAME even though + redistribution of LAME may also require a patent license. + +2. You agree not to enforce any patent claims for any aspect of + MPEG audio compression, or any other techniques contained in + the LAME source code. + +-=-=-=-=-=- +The following is from the LICENSE file from the lame source: +-=-=-=-=-=- + +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 + these modifications back to the LAME project, under the LGPL. + + +*** IMPORTANT NOTE *** + +The decoding functions provided in LAME use the mpglib decoding engine which +is under the GPL.

In particular, you +can include a compiled version of the LAME library (for example, +lame.dll) with a commercial program. Some notable requirements of +the LGPL: + +1. In your program, you cannot include any source code from LAME, with + the exception of files whose only purpose is to describe the library + interface (such as lame.h). + +2. Any modifications of LAME must be released under the LGPL. + The LAME project (www.mp3dev.org) would appreciate being + notified of any modifications. + +3. You must give prominent notice that your program is: + A. using LAME (including version number) + B. LAME is under the LGPL + C. Provide a copy of the LGPL. (the file COPYING contains the LGPL) + D. Provide a copy of LAME source, or a pointer where the LAME + source can be obtained (such as www.mp3dev.org) + An example of prominent notice would be an "About the LAME encoding engine" + button in some pull down menu within the executable of your program. + +4.
