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

Biquad Peaking Equalizer Filter (functional)

Description

Design biquad peaking equalizer filter and perform filtering. Similar to SoX implementation.

Usage

functional_equalizer_biquad(
  waveform,
  sample_rate,
  center_freq,
  gain,
  Q = 0.707
)

Arguments

waveform	(Tensor): audio waveform of dimension of (..., time)
sample_rate	(int): sampling rate of the waveform, e.g. 44100 (Hz)
center_freq	(float): filter's central frequency
gain	(float): desired gain at the boost (or attenuation) in dB
Q	(float, optional): https://en.wikipedia.org/wiki/Q_factor (Default: 0.707)

Value

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