[Vorbis-dev] Psychoacoustic model

[venkat]

Hi

I am trying to understand the psychoacoustic model used in the Oggvorbis 
encoder by looking at the source. I found it very difficult to understand. 
Does any one has any idea on this?  Can I get any information on the 
reference papers (JASA, AES or IEEE ASSP) which can be referred to 
understand this source code? Can I know who is the author of this module?

Regards
Venkat
