hi, i was playing around with apple's vdsp library the other day and was quite impressed by the performance. so i sat down and tried to implement a straight pitch-tracker (using square difference function) in a max-external.

i don't have time to finish the project properly right now. but since the question for a pitch-tracking alternative came up several times lately, i decided to make it available, although it might not be ready for prime time.

for anyone willing to test this out:

osx only (obviously).

please contact me off list for any issues you have with it. (hope i got the linking right...)

volker.
