`functional_lowpass_biquad.Rd`

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

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

- 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`

)

`tensor`

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