Patent ID: 8031879

Claim:
A sound processing system for a vehicle, comprising: a crossbar matrix mixer configured to receive a front input signal, a center input signal and a rear input signal; a center channel volume compensator connected to the crossbar matrix mixer, the center channel volume compensator configured to receive a center output signal from the crossbar matrix mixer; and at least one of a front channel volume and a rear channel volume compensator connected to the crossbar matrix mixer, the front channel volume compensator configured to receive at least one front output signal from the crossbar matrix mixer, the rear channel volume compensator configured to receive at least one rear output signal from the crossbar matrix mixer; and where the center channel volume compensator independently and selectively adjusts a volume gain for the center output signal in response to an input signal, where the front channel volume compensator independently increases the volume gain for the front output signal in response to the input signal, where the rear channel volume compensator independently increases the volume gain for the rear output signal in response to the input signal, and where at least one of the front input signal and the center input signal is combined with the rear input signal by the crossbar matrix mixer to synthesize a virtual center channel in a rear seating area of the vehicle.
