Filters¶

Filter bank construction¶

`mel`(sr, n_fft[, n_mels, fmin, fmax, htk, norm])	Create a Filterbank matrix to combine FFT bins into Mel-frequency bins
`chroma`
`constant_q`
`semitone_filterbank`

`window_bandwidth`
`get_window`(window, Nx[, fftbins])	Compute a window function.

`constant_q_lengths`
`cq_to_chroma`
`mr_frequencies`
`window_sumsquare`(window, n_frames[, …])	Compute the sum-square envelope of a window function at a given hop length.
