Parametric Equalizer (PARAMETRIC EQ)
This function has three interacting parameters, each with its own control input page: center
frequency, width, and amplitude. The center frequency is the center of the range of frequencies
that will be boosted or cut by the amplitude setting. The width is the entire range of frequencies
