A build log on a 5-band parametric equalizer written entirely in MATLAB: the filter design in detail, the pole-zero reading that tells you what a filter does before you plot it, and an honest audit of where my implementation diverges from its own UI. Five cascaded biquads, RBJ cookbook coefficie...
