Patent ID: 8031880

Claim:
A signal processor for use in an audio system for a vehicle, the signal processor providing a plurality of operating modes, wherein the operating modes comprise: a first operating mode characterized by: equal total sound pressure levels at each of a plurality of seating locations, from radiation corresponding to a plurality of output channels, a first equalization pattern that when applied to audio signals results in a similar frequency response at each of the seating locations, and a first balance configuration that when applied to the audio signals results in similar balance patterns at each of the seating locations; and a second operating mode characterized by: greater sound pressure levels at a first of the seating locations than at others of the seating locations, from radiation corresponding to the plurality of output channels, a second equalization pattern that when applied to the audio signals results in a frequency response at the first seating location that is smoother than the frequency responses at others of the seating locations, and a second balance configuration that when applied to the audio signals results in the balance pattern at the first seating location being more balanced than the balance patterns at others of the seating locations.
