I have my iPod loaded with music and generally listen to it through my car stereo. Inevitably, there are very loud songs; I have to turn the stereo down to 4 or 5. There are also very quiet songs; I have to turn the stereo to 20 or 25 to hear them properly.

Is there a way to increase the loudness (if that is the correct term) of the quiet mp3s so that I don't have to turn the stereo up to such a large volume?

Ideally it will be a non-destructive change and reversible if the results sound horrible. It should allow me to specify an mp3 with the target loudness and make the other mp3s as loud.

The mp3s are mixed and generally not from the same artist or album. It would also be nice to get a report of the changes before they are made so I can listen for my self to see what would happen.

Thanks, Troy

I think MP3Gain should match your needs. It offers a bit more than normalization (manipulating multiple mp3 files to have about the same volume level), while all changes are loss-less and reversible.

What you want is ReplayGain. The MP3Gain that Jazz mentioned is just one of many applications that can generate ReplayGain metadata.
