In curso-r/torchaudio: R Interface to 'pytorch''s 'torchaudio'

All-pass Biquad Filter (functional)

Description

Design two-pole all-pass filter. Similar to SoX implementation.

Usage

functional_allpass_biquad(waveform, sample_rate, central_freq, Q = 0.707)

Arguments

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

Value

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