[MPlayer-users] Clipping with volnorm

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?

audacity screenshot from file with speech:


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

-af format=floatle,volnorm=1:0.25,resample=96000:0:2,format=s32le
-af format=floatle,resample=96000:0:2,format=s32le
