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.
