How can I normalize the sound levels in several different audio/MP3 files?

How can I normalize the sound levels in several different audio/MP3 files? I have a given set of MP3 audio files of varying audio levels. I would like to know how I can automatically normalize all of these files, so the volume is amplified/raised on the quieter files, and lowered/muted on the louder files.

Audacity

"Audacity is great, but you might also want to check out Levelator.

Levelator adjusts the audio levels within your podcast or other audio file and it runs on Windows, Mac OS X, and Linux.

I hope this helps."

On Windows, I do it within my music player, foobar2000.

"mediamonkey will set replay-gain idv3 fields of your mp3 files quite nicely.
highlight the file(s) and right-click [Analyze Volume] to set the replay-gain fields.
I think it can do it automatically as well (config option someplace)
