librosax.feature.cqt_frequencies

cqt_frequencies(*, n_bins: int = 84, bins_per_octave: int = 12, fmin: float = 32.7, tuning: float = 0.0) → Array

Compute the center frequencies of Constant-Q bins.

Parameters:

• n_bins – Number of frequency bins

• bins_per_octave – Number of bins per octave

• fmin – Minimum frequency (Hz)

• tuning – Tuning deviation from A440 in fractions of a bin

Returns:

Center frequencies for each CQT bin

Return type:
