Function aubio_sys::aubio_filterbank_set_mel_coeffs_htk

pub unsafe extern "C" fn aubio_filterbank_set_mel_coeffs_htk(
    fb: *mut aubio_filterbank_t, 
    samplerate: smpl_t, 
    fmin: smpl_t, 
    fmax: smpl_t
) -> uint_t

Mel filterbank initialization

\param fb filterbank object \param samplerate audio sampling rate \param fmin start frequency, in Hz \param fmax end frequency, in Hz

The bank of filters will be initalized to to cover linearly spaced bands in the Htk mel scale, from fmin to fmax.
