[vorbis] RC2 vs. beta4 (test)

[Attila Padar]

Hi!
I would like to share with you an interesting test result.
I re-encoded a song 10 times (the 2. made from the 1.,
the 3. made from the 2.,... the 10. made from the 9.), 
with a beta4 (CVS 20010620)
and with an RC2 (CVS 20010817) library version,
256 kbit/s mode, channel coupling disabled at RC2.
The beta4 is very good at the 10. encoding too,
but the RC2 has some interesting quality bugs.
So, the songs:
They are OGG files (not compressed zip), 
just rename them to OGG!
1. encoding with beta4:

10. encoding with beta4:

10. encoding with RC2:
http://www.geocities.com/mpxplay/010817_10.zip

I tested on lower bitrates and with channel coupling too.
With similar results...

Attila
