class espnet2.gan_codec.shared.discriminator.msmpmb_discriminator.MultiBandDiscriminator(window_length: int, hop_factor: float = 0.25, sample_rate: int = 44100, bands: list = [(0.0, 0.1), (0.1, 0.25), (0.25, 0.5), (0.5, 0.75), (0.75, 1.0)], channel: int = 32)

Bases: Module

Complex multi-band spectrogram discriminator. :param window_length: Window length of STFT. :type window_length: int :param hop_factor: Hop factor of the STFT, defaults to 0.25 * window_length. :type hop_factor: float, optional :param sample_rate: Sampling rate of audio in Hz, by default 44100 :type sample_rate: int, optional :param bands: Bands to run discriminator over. :type bands: list, optional

forward(x)

Defines the computation performed at every call.

Should be overridden by all subclasses.

NOTE

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
