Abstract:
1. An audio system comprising: a first compensation channel configured to receive a first audio signal, the first compensation channel including a series connected delay circuit and frequency equalizer circuit to generate a first compensated audio signal; a second compensation channel configured to receive a second audio signal, the second compensation channel including a series connected delay circuit and frequency equalizer circuit to generate a second compensated audio signal; a first summing circuit having inputs to receive the first audio signal and the second compensated audio signal, where the first summing circuit generates an output signal for provision to a first speaker to generate a first audible sound; and a second summing circuit having inputs to receive the second audio signal and the first compensated audio signal, where the second summing circuit generates an output signal for provision to a second speaker to generate a second audible sound, and where the first compensated audio signal is configured to drive the second speaker to constructively add, at a listening position, the first compensated audio signal to the first audible sound generated by the first speaker and where the first compensated audio signal arrives at a predetermined delay after an arrival of the first audible sound and is psychoacoustically perceived at the listening position as arriving with the first audible sound, and where the second compensated audio signal is configured to drive the first speaker to constructively add, at the listening position, the second compensated audio signal to the second audible sound generated by the second speaker and where the second compensated audio signal arrives at a predetermined delay after an arrival of the second audible sound and is psychoacoustically perceived at the listening position as arriving with the second audible sound, where the constructive additions at the listening position compensate for deviations in a target frequency response at the listening position.
