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, a BSD-license software implementation of the Vorbis
|
|
specification by the Xiphophorus company.
|
|
|
|
- libvorbisfile, a BSD-license convenience library built on Vorbis
|
|
designed to simplify common uses.
|
|
|
|
- libvorbisenc, a BSD-license library that provides a simple,
|
|
programmatic encoding setup interface.
