I recently had need of a de-esser, which led me to wonder about doing
it in Csound.  I only have a vague idea of how they work, and have
only done a little experimenting with the Nyquist plug-in to audacity.

Has anyone constructed one, or could point me at an understandable
explanation?  My particular need is for speech but I assume it would be
the same for vocals.

You can use a BP filter or a bank o them to measure the signal energy > 5K and then use the 
result to control the gain of the signal (inverse-proportionally), with some lp filtering (port) to
control the gain transition.

Thank you Iain.  I tried your code, slightly modified for my need (mono, 
from disk) and it worked nicely without adjusting the parameters.  I think 
I will constitute it as a UDO and see what the parameters do.
