Abstract:
1. A computer readable medium containing program instructions for controlling a parametric equalizer, comprising: computer readable code for displaying a composite equalization curve, a first frequency curve with a first center frequency, a second frequency curve with a second center frequency, and a third frequency curve with a third center frequency, wherein the composite equalization curve is formed from at least the first frequency curve, the second frequency curve, and the third frequency curve; computer readable code for allowing a dragging movement of the first center frequency, the second center frequency, and the third center frequency; computer readable code for providing real time changes in equalization according to changes in the equalization curve caused by dragging movement; computer readable code for displaying a plurality of presets, wherein each preset is displayed as a thumbnail composite curve that graphically indicates the equalization provided by the preset; and an output amplifier electrically connected to the parametric equalizer, wherein the equalization curve represents an equalization curve of the output amplifier.
