Well, not directly, but one of my projects "LouderBox" does sort of what you 
are looking for (8 bands) but then it re combines them after 
compressing/limiting/clipping the hell out of them. Should be easy to add 
individual outputs for the bands but it just had not seemed that useful to 
me. 

Get the CVS version it is rather more satisfactory then the tarball which is 
horribly broken.

http://www.spamblock.demon.co.uk/louderbox.html for the rather hairy details. 

CPU Load is rather (very much) on the high side as optimisation has not 
exactly happened yet. 

Regards, Dan.
