The normalize program does that for me.

Summary     : A tool for adjusting the volume of wave files
Description :
normalize is an overly complicated tool for adjusting the volume of
wave files to a standard volume level.  This is useful for things like
creating mp3 mixes, where different recording levels on different
albums can cause the volume to vary greatly from song to song.

G'luck....
