-vol
parameter is confusing me.
256 => normal (i guess meaning same as input volume, no change)
512 => (double the volume - read this somewhere).
So what to do for 3 times the volume? 1.5 times the volume?
Basically, lets say I have the max sound amplitudes (audacity levels) in 3 files as:
0.8
0.6
0.9
I want to amplify in the first two files, so that max=0.9
in all files. What parameters of -vol
I would use?
