Vorbis is a general purpose audio and music encoding format
contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond
MPEG audio layer 3. Unlike the MPEG sponsored formats (and other
proprietary formats such as RealAudio G2 and Windows' flavor of the
month), the Vorbis CODEC specification belongs to the public domain.
All the technical details are published and documented, and any
software entity may make full use of the format without royalty or
patent concerns.

This package contains libvorbis, an LGPLed software implementation of
the Vorbis specification by the Xiphophorus company
(http://www.xiph.org/), vorbisfile, an LGPLed convenience library
built on Vorbis designed to simplify common uses and a number of GPL
example programs, utilities and player plugins.
