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 20):
The medium of  claim 18 , further comprising instructions that, when executed by the processor of the smart loudspeaker, cause the processor to calibrate the array of microphone elements by convolution of the electrical signals from each of the microphones using a minimum phase correction filter and a target microphone that is one of the microphone elements of the array.
