ConvTasNetaD  ConvTasNet separation model, as described in [1].

    Args:
        n_src (int): Number of sources in the input mixtures.
        out_chan (int, optional): Number of bins in the estimated masks.
            If ``None``, `out_chan = in_chan`.
        n_blocks (int, optional): Number of convolutional blocks in each
            repeat. Defaults to 8.
        n_repeats (int, optional): Number of repeats. Defaults to 3.
        bn_chan (int, optional): Number of channels after the bottleneck.
        hid_chan (int, optional): Number of channels in the convolutional
            blocks.
        skip_chan (int, optional): Number of channels in the skip connections.
            If 0 or None, TDConvNet won't have any skip connections and the
            masks will be computed from the residual output.
            Corresponds to the ConvTasnet architecture in v1 or the paper.
        conv_kernel_size (int, optional): Kernel size in convolutional blocks.
        norm_type (str, optional): To choose from ``'BN'``, ``'gLN'``,
            ``'cLN'``.
        mask_act (str, optional): Which non-linear function to generate mask.
        in_chan (int, optional): Number of input channels, should be equal to
            n_filters.
        causal (bool, optional) : Whether or not the convolutions are causal.
        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.
