Well, that's nice to know about. Thanks!
Just wanted to add that I've tried two others -
denoi and anoi - command line programs which can also
be used from within Snd.
IIRC, one is a more advanced version of the other, so
check the home page (findable from Dave Phillips' site)
and just grab the more recent one.
I found that noise could be reduced quite well, but
there were noticeable artifacts - quite a lot of signal
gets lost along with the noise. Not just treble loss;
there's some odd time smearing or something going on.
But I didn't play with the parameters very thoroughly.
