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

[James Snook]

I ripped all my cd's using Cdex latest development version (so the
codecs are stable, and I use paranoia, so beta is not very important
here) and used ogg Vorbis 1.0, I had to email the author to confirm
that, but it was 1.0, LAME was second to newest version at the time.  I
encoded each album 5 times each, one mp3 and 4 Vorbis and then used the
same lib files in Cdex to convert them back to .wav for proper testing
in WinABX.  If anyone is actually interested I can recreate the tests to
an extent and make new logs, but I promise I am not bending the truth
here, as it would achive nothing (and it took 7 solid days and 15GB of
space :)
But, not a beta codec nor extration.
Oh, last note, I extracted each Cd once, then converted the same wav's
over and over for maximum fairness.

What version of Vorbis? that sounds like the behavior of beta 3 or 4.
Unfortunately, there are still 'new' windows encoders out there using
the old versions.

If it's a 1.0 encoder, I'd like to hear these samples myself.

I personally prefer the less biased forums at Hydrogen Audio.
