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
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...)
