torchaudio.prototype.functional.sinc_impulse_response(cutoff: Tensor, window_size: int = 513, high_pass: bool = False)

DEPRECATED

Warning

This function has been deprecated. It will be removed from 2.9 release. This deprecation is part of a large refactoring effort to transition TorchAudio into a maintenance phase. Please see https://github.com/pytorch/audio/issues/3902 for more information.

Create windowed-sinc impulse response for given cutoff frequencies.

Parameters

• cutoff (Tensor) – Cutoff frequencies for low-pass sinc filter.

• window_size (int, optional) – Size of the Hamming window to apply. Must be odd.

• (Default –

• high_pass (bool, optional) – If True, convert the resulting filter to high-pass. Otherwise low-pass filter is returned. Default: False.

Returns

A series of impulse responses. Shape: (…, window_size).

Return type

Tensor
