Digital parametric equalizer with symmetrical cut and boost spectrums
 An improved digital parametric equalizer realized by software stored in a computer readable memory. The computer readable memory stores a first and a second set of instructions. The first set of instructions determines a value of a tuning coefficient based upon whether a parametric equalizer is to cut or to boost an input signal. The second set of instructions implements a filter to realize the parametric equalizer. The second set of instructions uses the value of the tuning coefficient and the input signal to produce an output signal having substantially symmetrical cut and boost spectrums.
