#include "util/biquad.h" Triple band parametric with shelves

Actually five bands of eq, but the first and last are locked to shelving filters.

For extreme cuts on the shelves, recomended values are about -30dB for the gain and 1.0 for the slope.

For details see the single band parametric (section \ref{singlePara}).
