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....
