In fact, I didn't make a real test with vorbis 96 and 128. I just use ist with
divx-films, and my onboard-sound isn't too good. there are quite few
differences to the original, so it is realy good in this case.
Well, let's talk about hardware: Dynaudio Contour 1.1, cyrus 5, Marantz
Original SE, Mogamie blue rocket, Sun audio wire transfer. This really is
nothing like 20$ speakers. I may tell you, that I dint't buy these, just
because I like to spend a lot of money. As a student of musics, I dont hear
Anyway, with vorbis 128 and wav, the differences were really rare. in most
cases, i really couldn't tell, which one was better. When i tested the
codecs, I did this over cd, just because i didn't want to use my soundcard.
out of 10 files in mp3, vorbis and wav, i rated mp3 always worse, and 6 or 7
wav best. of course, i rated blind.
In a german computer magazine, there was a test, too. There were about 3000
participants, and the results were quite similar. Some professionals as to
balance engineers or producers also rated, with similar results.
ok, there are some few differences between the files, but i would recommend
you, to make a test with some files, where you don't know what codec was
used. if you already did so, and you rated wav 100% right - congratulations,
and take care of your ears, they are something realy special!

you see, mp3 has more information, but anyway worse quality.
If you really want to keep all audio information, what is not necessary in
most cases, i would recommend something like shorten. i would discribe this
as a special kind of zip file for audio. you won't lose any information this
