nnmnkwii.functions.modphase¶

nnmnkwii.functions.modphase(y, n=4096, norm=None)[source]¶

Phase of modulation spectrum.

Given an parameter trajectory, it computes phase of modulation spectrum.

Parameters:	n – DFT length norm – Normalization mode. See `numpy.fft.fft()`
Returns:	Modulation spectrum as `T x n//2 + 1` complex array.
Return type:	numpy.ndarray
