Args: n_src (int): Number of masks to estimate. out_chan (int or None): Number of bins in the estimated masks. Defaults to `in_chan`. bn_chan (int): Number of channels after the bottleneck. Defaults to 128. hid_size (int): Number of neurons in the RNNs cell state. Defaults to 128. chunk_size (int): window size of overlap and add processing. Defaults to 100. hop_size (int or None): hop size (stride) of overlap and add processing. Default to `chunk_size // 2` (50% overlap). n_repeats (int): Number of repeats. Defaults to 6. norm_type (str, optional): Type of normalization to use. To choose from - ``'gLN'``: global Layernorm - ``'cLN'``: channelwise Layernorm mask_act (str, optional): Which non-linear function to generate mask. bidirectional (bool, optional): True for bidirectional Inter-Chunk RNN (Intra-Chunk is always bidirectional). rnn_type (str, optional): Type of RNN used. Choose between ``'RNN'``, ``'LSTM'`` and ``'GRU'``. num_layers (int, optional): Number of layers in each RNN. dropout (float, optional): Dropout ratio, must be in [0,1]. in_chan (int, optional): Number of input channels, should be equal to n_filters. fb_name (str, className): Filterbank family from which to make encoder and decoder. To choose among [``'free'``, ``'analytic_free'``, ``'param_sinc'``, ``'stft'``]. n_filters (int): Number of filters / Input dimension of the masker net. kernel_size (int): Length of the filters. stride (int, optional): Stride of the convolution. If None (default), set to ``kernel_size // 2``. sample_rate (float): Sampling rate of the model. **fb_kwargs (dict): Additional kwards to pass to the filterbank creation.
