I would like to stack biquads so that the peak is flattened, is there a formula to stack bi-quads in this way?
Theres a type of filter in DMG eqilibrium called butterworth but its a peak filter, I have attached an image the peak filter on the right is the “butterworth” the one next to it on the left is two normal peak filters that seem to result in a similar response. Is there an algorithm to build cascaded peak filters like this?
