Does anybody out there have experience implementing the
autocorrelation method of pitch detection?  I have the algorithm in
front of me, and some code that works for a large sample, but am
having problems getting the thing to reliably work on shorter
samples of data (30ms, where the signal only repeats only twice).

Thanks!
