Abstract:
A digital signal processor is programmed to extract a center channel from a stereo input, apply the center channel to an array of speaker elements using a first set of finite impulse response filters and a first rotation matrix to generate a first beam of audio content at a target angle about the axis, apply a left channel of the stereo input to the array of speaker elements using a second set of finite impulse response filters and a second rotation matrix to generate a second beam of audio content at a first offset angle from the target angle about the axis, and apply a right channel of the stereo input to the array of speaker elements using a third set of finite impulse response filters and third rotation matrix to generate a third beam of audio content at a second offset angle from the target angle about the axis.

Claim (Index 2):
The smart loudspeaker of  claim 1 , wherein to extract the center channel using the digital signal processor comprises a high-frequency path that performs center extraction on high frequencies at a first sampling rate, a low-frequency path that performs center extraction on low frequencies at a second sampling rate lower than the first sampling rate, and an adder that combines an output of the high-frequency path and an output of the low-frequency path to create the center channel.
