Patent ID: 7813825

Claim:
A method for providing a graphical interface for dynamic range control of an audio signal, the method comprising: displaying a main rectangle on a display, wherein the rectangle's horizontal axis represents audio frequency and the rectangle's vertical axis represents audio amplitude; dividing the main rectangle into a plurality of frequency band rectangles, wherein each frequency band rectangle represents a different frequency band, and wherein each frequency band rectangle is separated from another frequency band rectangle by a line that is movable horizontally by a user to change the frequency at which the frequency bands are divided; and dividing each of the plurality of frequency band rectangles into a plurality of controller rectangles, wherein each controller rectangle represents a different dynamic range controller to be applied for a particular frequency band, and wherein each controller rectangle is separated from another controller rectangle by a line that is movable vertically by a user to change an amplitude threshold at which the corresponding controller should begin to apply dynamic range control on the audio signal.
