is there a way to equalize the volume of tracks?

Is it possible to equalize the volume of a group of mp3-files?

Because i have about 1000 tracks with big difference between volume, so when is change to another song in amarok, i need to change the volume.

Is there a program that can equalize the volumes?

i tried it, i wan't to equalize 2 cd's so i used this command:

Code:

normalize album1/*.mp3 album2/*.mp3

It seems that it doesn't do anything. Am i doing something wrong? Do i have to use the -b or -m options?

Can't say I'm an expert, but I always use the -m switch. You should get an output that shows the dB adjustment of each mp3 file similar to

Code:

i tried it with the -m switch, but the differemce between 2 albums is still big. Is there a way to increase the volume of an album by hand? Just by giving a value to get it that value louder?
