You might look for an audio editor that has batch processing features.

The process you desire is called 'Normalizing' and will adjust the peaks to be at 100% (or whatever level you want).

Of course this process does modify the sound - and of course the low-level noise that is there.. so be careful, if used to the extreme it can sound crunchy (those lower level bits don't regenerate, they just hang there...ha!)

Cross platform Audacity is free. But there doesn't seem to be any batch features.

Sound Studio for the Mac is great and really easy to use, however no batch features.

BabaBatch is incredible and coverts everything to everything but is pricey.

Quicktime Pro might even do this....perhaps you can do it all in Rev using Applescripts... you need to find an Audiounits plugin that will normalize.




I have a stack which uses a large number of audio files, and unfortunately they were recorded at various volume levels. I would like to "even them out" so that they sound more matched with each other, volume-wise. Does anyone have a suggestion as to a utility that can accomplish this? It is not practical in my situation merely to use the Rev QT player object to play them back at different levels; I need to actually modify the sound files themselves.

Thanks,
Kurt
