It's a multimedia container similar to avi. What people mostly use is Ogg Vorbis which is the audio codec, much like MP3. It is better than mp3 for many reasons. First, it's free of silly patents. The specification is in the public domain, the floating point implementation is under a BSD license and the utilities are GPL. Second, it uses much better acoustical models than the older original mp3 (mp3 pro, aac, and other newer codecs compare very well with vorbis). Thirdly, it is variable bit rate (VBR) so you don't waste bits encoding blank space and it can bump but the bit rate when a really complex section presents itself. Overall it uses less space for better quality than mp3. Fourthly, it can be "peeled", meaning you can stream multiple bit rate streams from the same high rate source. For example, you run an internet radio station with 128k, 64k, 32k, and 16k streams. With mp3, you must encode 4 different streams from the same source. But with vorbis, you can encode the 128 and peel the extra bits off the stream for each of the lower rate streams. Saves tons of CPU time.
