Ogg Vorbis streaming
The Icecast project provides Free Software tools for the encoding and streaming of audio in the open, non-proprietary Ogg Vorbis format. Whilst working with (and on) these tools during the BBC's Ogg Vorbis streaming trials, I wrote some documentation for ices2, the encoder part of the toolchain.
Audio: Richard Stallman Speech
In June 2002, Richard M. Stallman, founder of the GNU Project came to Aberystwyth to give a talk on Copyright vs. Community in the Age of Computer Networks and The Dangers of Software Patents. I encoded this in the Ogg Vorbis format, and BBC Internet Services streamed it live for anyone on the Internet (first live streamed RMS talk in Ogg Vorbis - possibly in any format, due to his natural objection to patent encumbered codecs). I've split it into three parts here.
