[edit] What is Ogg Vorbis?

Ogg (or more precisely, Ogg Vorbis) is an audio codec much like mp3. You can use it to compress music to a fraction of its original size.

Ogg Vorbis is being developed by the Xiph.org foundation (http://www.xiph.org). The project homepage is at http://www.vorbis.org.

(Btw, just "Ogg" without the vorbis denotes a more general codec container format. The Xiph folks a developing a speech and video codec as well, and you might have heard about "Ogg Speex" and "Ogg Theora", two other codecs sharing the same wrapper with Vorbis.)

[edit] How does Ogg Vorbis compare with mp3?

  • It has a vastly better sound quality at low bitrates.
  • If you don't care about quality, you can get much higher compression while the sound is still recognizable.
  • It is free, mp3 is not. mp3 decoders are free for all, but writing an encoder requires licence fees.
  • It is slightly more cpu-intensive to encode and decode than mp3, and does not work as well on architectures without floating-point math (such as the ARM CPU used in many organizers and gadgets), but this is being constantly improved upon.
