asteroid.filterbanks.param_sinc_fb module¶

class asteroid.filterbanks.param_sinc_fb.ParamSincFB(n_filters, kernel_size, stride=None, sample_rate=16000, min_low_hz=50, min_band_hz=50)[source]¶

Bases: asteroid.filterbanks.enc_dec.Filterbank

Extension of the parameterized filterbank from [1] proposed in [2]. Modified and extended from from https://github.com/mravanelli/SincNet

Parameters:

n_filters (int) – Number of filters. Half of n_filters (the real parts) will have parameters, the other half will correspond to the imaginary parts. n_filters should be even.
kernel_size (int) – Length of the filters.
stride (int, optional) – Stride of the convolution. If None (default), set to kernel_size // 2.
sample_rate (int, optional) – The sample rate (used for initialization).
min_low_hz (int, optional) – Lowest low frequency allowed (Hz).
min_band_hz (int, optional) – Lowest band frequency allowed (Hz).

Variables:

n_feats_out (int) – Number of output filters.
