About Ogg Vorbis:

Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free,
general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz,
16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to
128 kbps/channel. This places Vorbis in the same competitive class as audio
representations such as MPEG-4 (AAC), and similar to, but higher performance
than MPEG-1/2 audio layer 3, MPEG-4 audio (TwinVQ), WMA and PAC.
