I was playing around with pvspitch.  When I sing into a mic, it tracks
great right out of the box with the instrument from the manual (very
cool!).  I do get a good amount of noise though: cracking and popping.
 This doesn't make sense because the sound in the example instrument
is only coming from the oscil, right?

I've tried all the usual things on my end, adjusting -b and -B,
checking my signal path, testing with simple in/out instruments and
everything is fine.

I've also played with the kthresh with little success.  I'm using the
instrument on the manual page verbatim. Does anyone else have this
problem?

Try adding a lp filter (port) in between pvspitch and oscil for
both kamp and kfreq. The clicking etc is probably due to
erratic changes in amp and freq, which need to be smoothed out.
