Its the EQ + xover processing thats taking all the CPU. I've had a lot of
requests for just the spectrum analyser part of JAMin without the
processing though - so maybe that could be seperated. It would be about
1/8th of the CPU load.

It would also be possible to add an option for time-domain processing of
the EQ and xover, whihc is a lot cheaper, but it would hcange the
behaviour and the HDEQ wouldn't work, which is one of the best features of
JAMin IMHO.

A jamin-users list sounds OK - do you want to set one up? You should have
enough privs on the sf.net system.
