Hi. Does anyone have a good reference for pitch tracking by
autocorrelation? I do note that there is a very long thread on this
topic, but it's too long to follow. So far I've written a very
straightforward program to calculate autocorrelation in a signal and
also a crude envelope follower to approximate volume at each pixel. I
now want to refine my approach and need a proper reference. What would
BTW: The signal will be monophonic human voice, and my application is a
multimedia one which doesn't have too stringent accuracy requirements.

Thanks. My library had a copy on the shelf and I have obtained it.
