anyone know of a program that can make all of your mp3's volume an equal level?

I know with goldwave you can, but i want to be able to do more then one at a time.

If you know of one please let me know, thanks

and by the way I use Creative to store my mp3s
itunes has that feature with the "sound check" but that only works with in itunes so you'll just have to put up with itunes if you want that
