nnAudio.librosa_functions.mel_frequencies¶
- nnAudio.librosa_functions.mel_frequencies(n_mels=128, fmin=0.0, fmax=11025.0, htk=False)¶
This function is cloned from librosa 0.7. Please refer to the original documentation for more info.
- 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) – If True, use HTK formula to convert Hz to mel. Otherwise (False), use Slaney’s Auditory Toolbox.
- Returns
bin_frequencies – Vector of n_mels frequencies in Hz which are uniformly spaced on the Mel axis.
- Return type
ndarray [shape=(n_mels,)]
