Hi
Is there anything i can install or setup for Mplayer/ALSA to achieve a live-normalisation of the volume when watching movies ?
It annoys me to fiddle with the volume slider every few seconds when i watch movies especially when the actors whisper so quiet that i have to raise the vol to the max and the next second an action scene occurs and my eardrum explodes.
I only found this so far:

Will the steps described on the link work on Arch ?
I would rather like something I can easily turn on and off or make it for MPlayer only and not a global setting (if possible).
Thanks in advance

For AC3 audio streams (most DVDs) a52dec can do it and Mplayer has its own internal version. I've never used it before, so I'll defer to the man page:
-a52drc <level>
Select the Dynamic Range Compression level for AC-3 audio streams. <level> is a float value ranging from 0 to 1, where 0
means no compression and 1 (which is the default) means full compression (make loud passages more silent and vice versa).
This option only shows an effect if the AC-3 stream contains the required range compression information.

I hate that with movie makers. Sometimes I want to shoot somebody in the leg.

But if they tell you that I've lost my mind, maybe it's not gone just a little hard to find...

They record for theaters, what else would you expect?

"-a52drc <level>" This did not have any effect for a video file I was watching.
mplayer -af volnorm=2:0.75 FooVideo.flv
Solves it for me.
From Normalize volume output in MPlayer , found via google.com/search?q=mplayer+normalize (this thread is the first, commandlinefu was the second)
