Remaster sound (make it louder)?

[Amorphus]

Any free programs that would make the sound in an avi and mpeg file louder?

*bump* as I'd like an answer to this too.

You need something with audio gain control. I know Adobe Premier can do this, but I don't know of any others.

You could get something like virtualdub to split off the .wav file for the sound, and have a soundless video file as well, then renormalize the sound, and splice them back together using virtualdub again. It should work.

I think virtualdub may have the renormalizing option built in, but if not, then just get something like cdex to do a .wav -> .wav and renormalize if you can.

watch out for clipping

You can do that, but it's hard to synch the audio back up. Everytime I tried doing that it was always a little off.

what you need is a program with audio compression (volume compression, not file compression). raising the volume tends to just make things distort. compressing (followed by raising the volume) creates the illusion of "loudness" without making the peaks any higher. but i don't know a free program for this.

What about a non-free program?

Audio Forge, Pro Tools come to mind.... You may be able to find a "light" version of Pro Tools around for Cheap / free
