Abstract
An endpoint device includes a microphone array and spaced-apart loudspeakers including an active loudspeaker among the loudspeakers that is closest to the microphone array. The endpoint device forms at the microphone array an audio receive beam having a main lobe pointed in a direction from which audio is to be received, and determines which of the loudspeakers are not in the main lobe. The endpoint device identifies at least one additional loudspeaker among the loudspeakers determined not to be in the main lobe and that is farther away from the microphone array than the active loudspeaker. The endpoint device spreads audio energy of input audio associated with, and intended for, the active loudspeaker across the active loudspeaker and the at least one additional loudspeaker, and no other ones of the loudspeakers, using a precedence effect.
