Abstract: A computer readable medium containing program instructions for controlling a parametric equalizer is provided. Generally, a computer readable code is provided for displaying a composite equalization curve, wherein the composite equalization curve is formed from at least a first frequency filter with a first center frequency, a second frequency filter with a second center frequency, and a third frequency filter with a third center frequency. A computer readable code is provided for allowing a dragging movement of the first center frequency, the second center frequency, and the third center frequency.
