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

[James Snook]

Sory, I should mention that the 2 CD's that really racked the codecs
were:
Godflesh; Hymns (for the sheer raw sound of the guitar, bass guitar,
drum and vocal)
Opeth; Blackwater Park (Black metal wich is based on a wide style, using
2 distorted guitars, bass drums vocals and acoustic instruments at once,
giving the codec a lot to maintain)
These two let me pick out Vorbis from wav a LOT more than the other 2 I
used.

Its probably a wrong assumption on my behalf, but I think perhaps a lot
of the testing going on in audio codecs revolve around popular music
wich is perhaps easier on the encoding process, I assume good classical
music is also a good test but I don't actually own any to try =)

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.
