[vorbis] An Analysis of the c't Codec Test

[James Snook]

I would gladly provide the CD's in WAV (takes a while on isdn mind you)
but that sadly is not exactly legal, advise me to the point where clips
become piracy and I'll cut `em up and post em online :)
This may take a bit longer than simple ISDN speed limits however as my
domain just expired (or is about to) and my host has vanished, nice
huh?!

<p><p>Well, I couldn't find music that I could abx at
-q6 or above, and it is mainly due to the famous
loud trebles thing. You should provide us some
sound clips that vorbis clearly "fails" to encode
at high -q. We can imagine what you're hearing,
but it's quite useless :)).
