For each filter type we apply the calculation rules presented in the book DAFX: Digital Audio Effects to compute the biquad coefficients based on given practical parameters (center frequency (fc), sampling rate (fs), gain, quality value (q), smoothing parameter (p)). Filter Updating. As mentioned earlier biquad filters are very flexible.

Refer to Robert Bristow-Johnson’s well-know biquad reference, “Cookbook formulae for audio EQ biquad filter coefficients” for comments on bandpass. (Note that despite different formulas, most of his filters are mathematically identical with mine, with the same approach but different factoring; I think the main exception is our shelving ...

Description. [SOS,SV] = iirparameq (N,G,Wo,BW) returns the coefficients of an Nth order IIR biquad digital parametric equalizer with gain G, center frequency Wo, and bandwidth BW. The coefficients are returned in a second-order section matrix, SOS, and a vector of scale values between each biquad stage, SV.
