Hi Park,

Thanks for your question!

The numbers are frame length and frame shift in frames, but in different methods these parameters have different names which could be confusing.

As a baseline we take Praat, with frame length = 0.04 s and frame shift = 0.01 s

This frame length, among other things, we set for YAAPT (frame_length = 40 ms)

Since sampling frequency is 44100, then 44100*0.04 = 1764 (this is win_c for YIN), 44100*0.01 = 441 (hop_s for YIN).

If you take a look at the variable pitchY, you will see these numbers in the parameters frame_size and frame_jump.
