Patent ID: 8127231

Claim:
An audio equalization system, comprising: a user control device; a processing device operatively connected to said user control device; and a display operatively connected to said processing device, wherein: said processing device executes computer readable code to create a first visual representation of a first audio signal for output on said display; wherein: said first visual representation is generated according to a method comprising the steps of: (a) labeling the perimeter of a circle with a plurality of labels corresponding to a plurality of frequency bands, such that moving radially inward or outward from any one of said labels represents a change in a signal amplitude at the frequency corresponding to said one of first labels; (b) identifying a first occurrence of a signal having a first amplitude at a first frequency; and (c) graphically indicating a point along a radial axis corresponding to said first amplitude; said radial axis connecting the center of said circle and said first label.
