librosa.core.mel_frequencies¶

librosa.core.mel_frequencies(n_mels=128, fmin=0.0, fmax=11025.0, htk=False)[source]¶

Compute the center frequencies of mel bands.

Parameters:	n_mels : int > 0 [scalar] number of Mel bins fmin : float >= 0 [scalar] minimum frequency (Hz) fmax : float >= 0 [scalar] maximum frequency (Hz) htk : bool use HTK formula instead of Slaney
Returns:	bin_frequencies : ndarray [shape=(n_mels,)] vector of n_mels frequencies in Hz which are uniformly spaced on the Mel axis.
