nnAudio.utils.complex_mul¶
- nnAudio.utils.complex_mul(cqt_filter, stft)¶
Since PyTorch does not support complex numbers and its operation. We need to write our own complex multiplication function. This one is specially designed for CQT usage.
- Parameters
cqt_filter (tuple of torch.Tensor) – The tuple is in the format of
(real_torch_tensor, imag_torch_tensor)
- Returns
The output is in the format of
(real_torch_tensor, imag_torch_tensor)
- Return type
tuple of torch.Tensor
