What is the situation with MPEG patents?
Consult http://en.wikipedia.org/wiki/MP3 Apparently mp3 codec licencing is handled via http://www.mp3licensing.com rather than the directly by teh Fraunhofer Intitute. See Eric Scheirer’s: MPEG, Patents, and Audio Coding FAQ: http://music.columbia.edu/cmc/music-dsp/FAQs/MPEG_FAQ.html If you need a decent audio compression/decompression engine for a custom application, consider using OGG Vorbis, which is a patent-free replacement for MP3. The quality is better, the format is not compatible though. http://www.vorbis.
