pybic.SpecToCoherence

pybic.SpecToCoherence(spec, lilguy=1e-06)[source]

Estimate cross-spectrum/-coherence from spectrogram.

Parameters:

spec (ndarray) – Input spectrogram.
lilguy (float) – Small value to avoid 0/0 errors.

Returns:

C,cc,cx = SpecToCoherence(...)

C (ndarray) - Cross-spectrum.
cc (ndarray) - Cross-coherence spectrum.
xx (ndarray) - “Coherogram”.

Return type:
