Subj: DSP and pulse noises ?

I have discovered a need at my QTH (for one band only) of ridding myself of
a pulse type emission (like ignition noise). I believe it is caused by some
machinary or generator at a nearby industrial plant. I doubt any I say could
ever be done about and I don't intend to pursue that avenue.

My idea for the solution would to be to use PC DSP.

The pulses are of fixed duration and amplitude and in theory would simply
require the audio from the soundcard to be muted for the pulse duration.

I guess this is quite simple to do but I don't posses the time or resources
to it myself and I am looking for any recommendations for software that can
*specifically* do such a task.

So far the software that I've tried has been unsuitable, and relies upon
noise reduction algorithms rather than a selectable muting period (much like
a noise blanker - which incidently is ineffective to my current situation).

Anyone know of any suitable software ?
