.ogg is an open-algorithm (and vorbis provide an open-source) method
for de-larging sound. It's superior to mp3 ethically because it uses a
non-patented (and presumably a non-patentable) algorithm primarily,
and perhaps also in quality. Personally once an mp3 gets above 192kbps
I can't tell any difference, and that's through a reasonably decent audio
system. .ogg's are meant to be comparable about a step up to mp3
(that is that a 192kbps mp3 is meant to be roughly the same quality as
the '160kbps' version of an .ogg -- though it's not strictly comparable
since ogg typically uses a variable bitrate conversion method). A better
example is file-size -- to get comparable sound, you can use a smaller .ogg
than you'd need for an mp3.
At least in theory. I don't think there's been any double-blind tests
done of the output yet. I've done a few informal tests, but as I say
my ears just can't pick up differences once you get above the average.
There's a couple of .dll's that you just bang into your winamp/plugins
directory : in_vorbis.dll, libvorbis.dll, and optionally out_vorbis.dll
and then winamp happily plays .ogg's natively. Under linux, most mp3
players understand ogg's natively already.
The encoder is a drag-n-drop box that you just dump .wav's onto and
a .ogg pops out a short while later. It's very neat. And cheaper than
the fraunhoffer codec.
http://www.vorbis.com/ has all the details and d/l's.
