Biquad Filter (functional)

Description

Perform a biquad filter of input tensor. Initial conditions set to 0. https://en.wikipedia.org/wiki/Digital_biquad_filter

Usage

functional_biquad(waveform, b0, b1, b2, a0, a1, a2)

Arguments

waveform	(Tensor): audio waveform of dimension of ⁠(..., time)⁠
b0	(float): numerator coefficient of current input, x[n]
b1	(float): numerator coefficient of input one time step ago x[n-1]
b2	(float): numerator coefficient of input two time steps ago x[n-2]
a0	(float): denominator coefficient of current output y[n], typically 1
a1	(float): denominator coefficient of current output y[n-1]
a2	(float): denominator coefficient of current output y[n-2]

Value

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