Nicholas, Geoff, and Malcolm,

For doing pitch detection with MAX/MSP, I hear that Miller Puckettes'
"Fiddle" works well. I think it is intended for musical applications.

Speaking of musical applications, I wonder if the ESPS pitch tracker
that Malcolm mentions works well for various instruments as well as
sung voice.

We've tried Praat on music, and it seems to work well, although we
haven't given it a thorough test.

Another algorithm to consider is Alain deCheveigne's YIN, which was
published in JASA last year. Both his and the Praat method are based
on subtractive autocorrelation, I believe.

It would be nice though to have the pitch come out (as a graph) in
some sort of musical pitch units like semi-tones or cents -- i.e., in
log freq units. I know this can be thrown together, but musicians
and musicologists could use a standalone program, ready-to-go.
