Hi Danijel,
the choice of window size has much to do with what your pitched source is
like. Usually the window should be long enough to include plenty of cycles
to fight

Thanks Alexander.
Thanks Xue.
Xue, you say:
It rarely matters much which window function to use. Both Hann and Hamming
are good. But if your pitch detector does differentiations, Hann might be
the preferable one
Hi music dsp,
In order to implement accuarate pitch detection we are sending input signal
through Fourier analysis stage. Are there any recommended settings with
regards to:
- Window frame size?
- Window overlap factor?
- Window type (Hamming, Hann, etc.)?
Thanks.

Pitch detection using FFT is probably not the best way to do it, but if you are
going to, here's a tutorial to get you started with windowing and frame size.
For overlap, the more often you do it the faster you'll be able to respond (to
a point). My tutorial does not do any overlapping.
