Abstract
A plurality of speakers are arranged within a listening space. An audio processor is configured to generate a plurality of sound zones within the listening space using the plurality of speakers. The audio processor is programmed to create zone audio signals to generate at least one bright zone in the plurality of sound zones, perform individual delay compensation to the zone audio signals to add additional delay to a subset of the plurality of speakers, the additional delay defined to adjust acoustical output from the subset of the plurality of speakers to match an amount of delay of a most-delayed speaker of the plurality of speakers to the plurality of sound zones, and transmit the zone audio signals to reproduce the at least one bright zone by the plurality of speakers.
