asteroid.filterbanks.analytic_free_fb module¶

class asteroid.filterbanks.analytic_free_fb.AnalyticFreeFB(n_filters, kernel_size, stride=None, **kwargs)[source]¶

Bases: asteroid.filterbanks.enc_dec.Filterbank

Free analytic (fully learned with analycity constraints) filterbank. For more details, see [1].

Parameters:	n_filters (int) – Number of filters. Half of n_filters will have parameters, the other half will be the hilbert transforms. 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`.
Variables:	n_feats_out (int) – Number of output filters.
