Running mp3gain recursively in album mode

If you are running linux and want to assign replay gain values to your mp3s recursively, you are currently out of luck since mp3gain does not yet have a recursive mode. The simple solution

find /path/to/mp3s -iname "*.mp3" -exec mp3gain -r -k -p {} \;

only works if you want to have radio gain mode, i.e. all mp3s are brought to uniform common volume.

But if you are like me and you would like to listen to whole albums at a time, the -a switch is your friend and the above solution does no longer work. I have written two small python scripts which do this, assuming your mp3s are sorted either like this:


Then you can use If instead your artists are grouped by initials like so:


then use Both scripts do the right thing, i.e. apply album gain to albums and radio gain to single songs. They are not exactly userfriendly, but you should manage. Both scripts are released under the GPL.

By the way, vorbisgain has a recursive mode which works (almost) perfectly (only almost, since it of course does not known when to apply album and when to apply radio gain).
