In torchaudio: R Interface to 'pytorch''s 'torchaudio'

Low-pass Biquad Filter (functional)

Description

Design biquad lowpass filter and perform filtering. Similar to SoX implementation.

Usage

functional_lowpass_biquad(waveform, sample_rate, cutoff_freq, Q = 0.707)

Arguments

waveform	(torch.Tensor): audio waveform of dimension of (..., time)
sample_rate	(int): sampling rate of the waveform, e.g. 44100 (Hz)
cutoff_freq	(float): filter cutoff frequency
Q	(float, optional): https://en.wikipedia.org/wiki/Q_factor (Default: 0.707)

Value

tensor: Waveform of dimension of (..., time)
