I am compiling a file with mp3's to listen to and all the mp3 songs have different volumes. Is here a way to change the volume of an mp3 file when recreating so that it will be consistent with the other songs? One song is barely audible and the next is blowing the speaker off the desk. When i change the Master Volume dial it does not change the volume on the new mp3 file. Does Replay Music have a volume adjustment that I am overlooking? Thanks. Doug
