Patent ID: 8023665

Claim:
A method for providing a system for high fidelity reproduction of the acoustic signal from a selected type of acoustical generator, the method comprising: (1) determining a selected location proximate to an acoustical generator; (2) placing a first microphone at said selected location, said first microphone including at least one of an air pressure sensor, a vibration sensor, a magnetic sensor, a light sensor and a heat sensor; (3) separately generating sounds from the acoustical generator to produce sounds as picked up by the first microphone; (4) playing reference sounds of the acoustical generator; (5) comparing the sounds of the acoustical generator as picked up by the first microphone with the reference sounds as generated by the acoustical generator; (6) determining first and second differences in level over first and second respective discrete frequency ranges between the sounds of the acoustical generator as picked up by the first microphone at the selected location and the reference sounds as generated by the acoustical generator; (7) providing a first filter element to compensate for said first difference in level over said first discrete frequency range; (8) providing a second filter element to compensate for said second difference in level over said second discrete frequency range; wherein at least one of the first and second filter elements includes at least two adjustable parameters selected from the following: gain adjustment parameter, frequency adjustment parameter, bandwidth adjustment parameter, and filter shape adjustment parameter; and a single control to make concurrent, predetermined changes to said at least two adjustable parameters; (9) constructing an equalizer for the first microphone with said first and second filter elements so as to compensate for the first and second differences between the sounds as picked up by the microphone at the selected location and the reference sounds as generated by the acoustical generator.
