Abstract

An automated process for equalizing an audio system and an apparatus for implementing the process. An audio system includes a microphone unit, for receiving the sound waves radiated from a plurality of speakers, acoustic measuring circuitry, for providing frequency response measurement signals; a memory, for storing characteristic data signals representative of the loudspeaker units and further for storing the frequency response measurement signals; and equalization calculation circuitry, for providing an equalization pattern signal responsive to the frequency response measurement signals and responsive to the characteristic data signals representative of the plurality of loudspeaker units. Also described is an automated equalizing system including acoustic measuring circuitry including a microphone for providing frequency signals representative of responses at a plurality of locations; a memory, for storing the signals representative of frequency responses at the plurality of locations; and equalization calculation circuitry responsive to the signals representative of the frequency responses for providing an equalization pattern signal.
