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.
