Audio normalization

[GeorgeForeman]

OK once I've got the dvd ripped into an MPG (usually as easy as copying the correct VOB and renaming to MPG if the size is not too large) some of them are very loud and others amazingly low audio volumes.

With MP3's it was always as easy as running the music through a batch normalizer like MP3gain or something and voila super loud and quiet ones are fixed. Is there any such cure for my computer stored dvd movies?

You'll have to demux audio stream from the VOB/MPEG file first, then run it through some sound editor. If it's mp2 audio as you would expect with a standard MPEG file, you can use TMPGEnc to normalize the volume. It can handle PCM (.wav) files as well. If you got AC3 audio, you can try changing the volume with BeSweet.

Once done, multiplex back original video and new audio streams with TMPGEnc for instance.
