Either a video editor that can do that or one that can handle dssi plugins would be great... alternatively an easy script - I think mencoder and ecasound should be able to do the trick, but that's already a little more fuss than I care about.
Maybe even mencoder alone... but before I spend my whole evening trying to figure this out, I was hoping somebody has already done something like that and can point me in the right direction. Simple is the key. I know plenty of complicated ways to do that.
If you can use Audacity to do it, I would use that to do it. You can tell Audacity to amplify the audio, and it has an option to prevent clipping (i.e. distortion because it's over-amplified). You can also use that program to listen to the audio and review it before you save it. If I were you, I'd use Audacity.
However, you can also fool around with the normalize program and/or with sox to do the same thing. Check out their manual pages on how to use them.
