Abstract
An audio receiver that receives left, right, and center audio channels for a piece of sound program content is described. A content processor in the audio receiver generates separate audio signals corresponding to each channel for driving corresponding transducers in left and right loudspeaker arrays. The content processor generates (1) first center audio signals for driving transducers in the left array to generate a first center pattern, (2) second center audio signals for driving transducers in the right array to generate a second center pattern, (3) left audio signals for driving transducers in the left array to generate a left pattern, and (4) right audio signals for driving transducers in the right array to generate a right pattern. The first and second center patterns collectively represent the center channel while the left and right patterns respectively represent the left and right channels.
