Hi I have to compare a psychoacoustic model used in mp3 with the one used in Ogg Vorbis. Is there any paper that descibes PAM (Ogg Vorbis) in detail? How a masking threshold is calculated? I will be very greatful for any information. marcszar -------------- next part -------------- An HTML attachment was scrubbed...
