which only addresses MP3 encoders. I realize
Michelle's original question was about MP3, but I
thought there might be interest in an open source
alternative to MP3. MP3 encoding actually requires
royalties ($25, though this is not really enforced),
is patent protected, and the "free" encoder is limited
to a certain bit rate (64kbps?)
(http://www.mp3-tech.org/patents.html). Vorbis's ogg
format is truly open and free, and because you can
encode at a higher bit rate, of higher quality. I have
found that the files are slightly larger, but it is
negligible.

What is Ogg Vorbis?

Ogg Vorbis is a new audio compression format. It is
roughly comparable to other formats used to store and
play digital music, such as MP3, VQF, AAC, and other
digital audio formats. It is different from these
other formats because it is completely free, open, and
unpatented. More information about Ogg Vorbis can be
found at Vorbis.com.

Why are these files in .ogg format instead of .mp3?

There are lots of reasons that content providers
switch to .ogg format. Many files will compress to a
smaller size with higher quality using Ogg Vorbis
instead of MP3. MP3 also carries patent licensing
restrictions which do not apply to Ogg Vorbis. Ogg
Vorbis is an artist-friendly, technologically advanced
audio codec. Releasing content in Ogg Vorbis is the
best way to show support for the work done by the
project.
