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

[Oddsock]

in case anyone is interested, I have built a win32 program which will 
perform a double blind listening tests..It will allow you to play each 
sample and allow you to rank them in order of quality.  The program will 
then send the results to a centralized server which saves it off to a DB 
and gives immediate feedback to the user the outcome of the test.

A few things though :

- I'd like to make it self contained (i.e. with an installer) which means 
including the wav samples with the listening test. With 3 1 minute WAV 
samples, that's 30MB..
- I don't have good samples..I'd like to use samples that show obvious 
differences b/w each of the codecs...
- I would like to do a 64kbps face-off with a 64kbps WMA8, MP3Pro, and 
Vorbis sample.  I can do the WMA8, and MP3Pro, but I need to wait for Monty 
to finish the RC1 encoder to provide a comparable OGG sample.

if there is anyone wanting to help, just let me know...
