Patent ID: 7483540

Claim:
An audio system, comprising: a source of audio signals; signal processing circuitry coupled to said source for processing said audio signals to produce processed audio signals; a plurality of loudspeaker units, coupled to said signal processing circuitry, constructed and arranged to be deployed about a room, for radiating sound waves responsive to said processed audio signals; a microphone unit, for receiving said sound waves and for transducing said sound waves to electrical signals; acoustic measuring circuitry, for receiving said electrical signals and providing frequency response signals; a memory, coupled to said acoustic measuring circuitry, for storing characteristic data signals of said loudspeaker units and further for storing said frequency response signals; and equalization calculation circuitry, comprising a microprocessor running a software program wherein said software program is constructed and arranged to automatically validate at least one of a first frequency response or a second frequency response by causing the source of audio signals to cause radiation of a first sound wave from a first of the plurality of loudspeaker units to produce the first frequency response at a first location and then radiation of a second sound wave from said first of the plurality of loudspeaker units to produce the second frequency response at said first location and comparing the first and second frequency responses, said equalization calculation circuitry coupled to said memory, for providing an individual equalization pattern signal for each loudspeaker unit responsive to said frequency response signals and said characteristic data signals of an associated one of said plurality of loudspeaker units.
