I have a bunch of mp3s that are awfully quiet. Even on max volume on my player, they're hardly intelligible.
On the other hand, I have a few mp3's with perfect volume all over, could be used as a reference. A coworker mentioned there is a way to "normalise" volume on sound files, but couldn't help me on how exactly it's done.
Anyone know how to do this on Ubuntu?
EASYMP3GAIN will work. Look in the ubuntu software center. It's pretty simple , when you run it you can select the whole directory and normalize the all the songs
MP3DIAGS will do it too, however it's interface is much more difficult to understand.
