Abstract
A method performed by an audio system within a room that includes a first loudspeaker that has a first beamforming array and a second loudspeaker that has a second beamforming array. The method obtains a sound program as several input audio channels. The method performs a beamforming algorithm based on the input audio channels to cause each of the arrays to produce a front beam pattern and a side beam pattern when the loudspeakers are close to an object within the room, where the front beam patterns are directed away from the object and the side beam patterns are directed towards the object and the beam patterns contain different portions of the sound program. The method performs a cross-talk cancellation (XTC) algorithm based on a subset of the input audio channels to produce several XTC output signals for driving the arrays when the loudspeakers are far away from the object.
