What other unique features does Ogg Vorbis have?
Vorbis has a well defined comment header that is easy to use and extensible and obviates the need for clunky hacks like ID3 tags. Vorbis has bitrate scaling – a feature that lets you adjust the bitrate of a Vorbis file or stream without reencoding; just chop the packets up in the sizes you want them. Vorbis files can be sliced and edited with sample granularity. Vorbis has support for many channels, not just 1 or 2. Vorbis files can be logically chained together.
