Hello,

I have been looking into the code of lame 3.96.1 particularly the psymodel.c where the variable pcfact is used, computed as pcfact =ResvSize * 0.5/ResvMax,
what does the variable pcfact mean?

what is its significant in pre-echo control as it was used there too?

Also what does the attack_intensity mean?, what is its influence in the psymodel.

Does anybody have a reference manual that I can refer to in order to understand it better.
