I tried to get this to work last summer when I was working on a piece
for csound and clarinet (http://www.campdeadly.com/clg/sensing.html).
I'm hoping to control a synth with a mic.

The below works okay in terms of sensing the pitch from my singing
into a mic.  Two problems:

1.  There always is a hard cutoff.  Is there a way to mitigate this
with a line or something?

2. I get occasional loud pops or cracks.  I can't tell if it is the
instrument or my system.

Can anyone help with this?

I'm already using portk to smooth out the values passed from pvspitch.
 I wonder if it has something to do with the threshold at which sound
is sensed by pvsanal.
