I don't know if mplayer can do it, but sox probably can.
You could use "-dumpaudio" in mplayer, process the sound
with sox, and then encode into video maybe with "-audiofile sound.wav -oac
mp3lame -ovc copy".
I haven't done this with sox, but it has zillion effects, for example this
might be useful:
[gain [initial-volume [delay ] ] ]
Compand (compress or expand) the dynamic range
of a sample.
