AAC psychoacoustic model - #ARIJIT BISWAS# - Nov 9 3:26:09 2007



Hi all!

Does anyone know how to translate the AAC psychoacoustic model scale-factor=
 information to the masking curve?
http://en.wikipedia.org/wiki/Masking_threshold

In layman=C2=92s word:
>From the AAC scale-factor thresholds and scale-factor band information, I w=
ant to get the masking curve that is a function of frequency (Hz) and SPL (=
dB).

Any help would be GREAT! :-)
Best Regards,
~Arijit
