Thats more what the Spectrum tab is for, but I've attached a simple patch
that hacks the frequency curve to be slower decaying (tweak dacay_rate to
change the speed) if you want to try it.

You need newer swh-plugins - but not too new, or the version of JAMin your
using wont run. Mea Culpa.

The limiter that goes with that JAMin is broken. I wouldnt use it for any
servious work that has to go hard to the limit point. If you do want to
use the limiter, best to get a CVS JAMin and latest swh-plugins.
