espnet2.enh.layers.beamformer_th.perform_WPD_filtering(filter_matrix: Tensor, Y: Tensor, bdelay: int, btaps: int) → Tensor

Perform WPD filtering.

• Parameters:
  • filter_matrix – Filter matrix (B, F, (btaps + 1) * C)
  • Y – Complex STFT signal with shape (B, F, C, T)
• Returns: (B, F, T)
• Return type: enhanced (torch.complex64)
