Patent attributes
An audio system including a left input channel signal, a right input channel signal, and a discrete center input channel. Circuitry removes correlated content from the left input channel signal and the right input channel signal and inserts the correlated content into the center input channel signal to provide a modified left input channel signal, a modified right input channel signal, and a modified center input channel signal. The modified left input channel signal is radiated by a directional loudspeaker so that radiation in a direction toward a listening area is less than radiation in other directions. The modified right channel input channel signal is radiated by a directional loudspeaker so that radiation in a direction toward a listening area is less than radiation in other directions.
