Your thinking of "Denormal" numbers.

A nice "quick" fix for these is:
if ( number < 0.000000001)
number = 0.0;

LADSPA vocoder in JACK Rack h=
as the same problem. Being already pretty experienced in this regard (heheh=
e) I can say that this is because of an effect which I forgot how is called=
when the plugin stops receiving the signal but continues to try to process=
data and starts going into calculations of really small numbers and it tri=
ggers a software part of your CPU and it uses a lot of resources, these cal=
culations. The developer should find a way to fix this somehow.
