Hi Patrick,

I believe that there are quite a few people using pitch tracking for
various things, and I believe that the current best practice for
general pitch tracking is to use sigmund~, as Frank pointed out.

Pitch tracking, especially multiphonic pitch tracking is still an
active research area and not an easy problem to solve, but if you're
restricting yourself to a single instrument you can boost your
accuracy by taking into account the harmonic profile of the
instrument.

Check out the slides at

for some good pitch-tracking info.
