ComputeDeltas

class torchaudio.transforms.ComputeDeltas(win_length: int = 5, mode: str = 'replicate')

Compute delta coefficients of a tensor, usually a spectrogram.

See torchaudio.functional.compute_deltas for more details.

Parameters:

• win_length (int, optional) – The window length used for computing delta. (Default: 5)

• mode (str, optional) – Mode parameter passed to padding. (Default: "replicate")

forward(specgram: Tensor) → Tensor

Parameters:

specgram (Tensor) – Tensor of audio of dimension (…, freq, time).

Returns:

Tensor of deltas of dimension (…, freq, time).

Return type:

Tensor
