[MPlayer-users] Clipping with volnorm

[William Brana]

Hello,

I'm trying to maximize volume without clipping, but there is a lot of
clipping with volnorm.
I checked file af_volnorm.c, but it seems to compute gain from average
value of sample instead of maximum. Isn't it broken?

It is better with method 2, but still with clipping.
