Abstract: An audio system including a rendering processor for separately rendering a dialogue channel and a center music channel. The audio system may include circuitry for extracting one or both of the dialogue channel or the center music channel from program material that does not include both a dialogue channel and a center music channel. The dialogue channel and the center music channel may be radiated with different radiation patterns.

Abstract: An three-way audio system that uses directional arrays for radiating mid-frequency acoustic energy and passive directional devices to radiate the high frequencies. the system includes a left channel, a right channel, and a center channel. A crossover network separates the left channel and the right channel into low frequency content, midrange frequency content, and high frequency content. An omnidirectional acoustical device radiates acoustic energy corresponding to the low frequency content of the combined left channel, right channel and center channel. A first directional array, comprising signal processing circuitry and more than one acoustic driver, radiates acoustic energy corresponding to the midrange content of one of the left channel and right channel signal so that more acoustic energy corresponding to the midrange content of one of the left channel signal and the right channel signal is radiated laterally than in other directions.

Abstract: 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.

Abstract: A signal processor for use in a vehicle audio system provides multiple operating modes. A first mode provides substantially equal total sound pressure levels at each seating location. A first equalization pattern provides a substantially similar frequency response at each of the seating locations, and a first balance configuration provides substantially similar balance patterns at each of the seating locations. A second mode provides greater sound pressure levels at a first seating location than at other seating locations. A second equalization pattern results in a frequency response at the first seating location that is substantially smoother than the frequency responses at other seating locations, and a second balance configuration results in the balance pattern at the first seating location being substantially more balanced than the balance patterns at other seating locations.
