[vorbis] as if you haven't seen this yet

I'm not on the list, so cc any replies directly to my address please.

I saw this discussion reading the archives, and thought I would mention an
idea I saw in the discussion on slashdot. Someone suggested that a good way
to do a test of lossy formats would be to take about  3 or 4 clips of around
a minute each, encode them to vorbis, mp3, mp3pro, wma and whatever else you
want to test, then decode them back to .wav files and post them for
download, not giving any clue as to which format they were originally in
(like name them clip1.wav, clip2.wav) then have people download and evaluate
them (providing the original .wav for a reference point, of course)

Once a preset number of people have evaluated them, and sent back their
comments on each (mabe have a form that they can fill out) then release teh
results telling which file was in what format.

I think this would probably be the best way to objectively test all the
available lossey sound formats, and I think that testing with as many people
as possible is probably preferrable, and more accurate to testing with just
a few so-called experts.

I might do this sometime if I have some free time and I figure out what
tracks would be appropiate to use, they would probably have to be either
non-copyrighted or I would have to have to get permission from the
copywright owner (unless 1 or 2 minute clips would be covered under fair
use, I don't know)
