The melspectrogram is also known as filterbank or fbank feature in audio community.

It is computed by multiplying spectrogram with Mel filter bank matrix.

Parameters:
|

sr(int): the audio sample rate.
|

The default value is 22050.
|

n_fft(int): the number of frequency components of the discrete Fourier transform.
|
||||
The default value is 2048,
|

hop_length(int|None): the hop length of the short time FFT. If None, it is set to win_length//4.
|

win_length: the window length of the short time FFt. If None, it is set to same as n_fft.
|
||||
The default value is None.
|
||||
window(str): the name of the window function applied to the single before the Fourier transform.
|
||||
The folllowing window names are supported: 'hamming','hann','kaiser','gaussian',

'exponential','triang','bohman','blackman','cosine','tukey','taylor'.
|
||||
The default value is 'hann'
|

center(bool): if True, the signal is padded so that frame t is centered at x[t * hop_length].
|
||||
If False, frame t begins at x[t * hop_length]
|

The default value is True
|
||||
pad_mode(str): the mode to pad the signal if necessary. The supported modes are 'reflect'
|

The default value is 'reflect'.
|

n_mels(int): the mel bins.
|
||||
f_min(float): the lower cut-off frequency, below which the filter response is zero.
|

htk(bool): whether to use HTK formula in computing fbank matrix.
|

norm(str|float): the normalization type in computing fbank matrix. Slaney-style is used by default.
|
||||
You can specify norm=1.0/2.0 to use customized p-norm normalization.
|
||||
dtype(str): the datatype of fbank matrix used in the transform. Use float64 to increase numerical
|

accuracy. Note that the final transform will be conducted in float32 regardless of dtype of fbank matrix.
