Ogg Vorbis - Free audio format

Ogg vorbis is a fully open, non-proprietary, patent and royalty free compressed audio format for high quality (44.1-48.0kHz, 16+ bit, polyphonic) audio and music and fixed and variable bitrates from 16 to 128 kbps/channel. This puts Vorbis in the same class as audio representations including MPEG-1, audio layer 3, MPEG-s audio (AAC and TwinVQ) and PAC.

Vorbis can both encode and decode as a single pass, real-time stream, and requires roughly the same encoding and decoding power as mp3. We anticipate that it will get faster as time goes on. Ogg vorbis uses the Ogg bitstream format; the correct extension is .ogg.

Ogg vorbis was created because mp3 is not truly free: MPEG consortium members claim you cannot create an mp3 encoder without infringing on their patents.
