SYSTEMS AND METHODS FOR ADAPTIVE ZONE CONTROL OF A LARGE SCALE AUDIO SYSTEM
Adaptive performance software, operating on a computing device, may be used to control an adaptive loudspeaker system within a venue. In some embodiments, the adaptive performance software may receive a selection of a target area within the venue. The adaptive performance software may then determine a smallest affected zone that includes the target area, and may present the smallest affected zone to the user to indicate what the affected area for the requested changes would be. In some embodiments, the adaptive performance software may take the shape of the venue, the capabilities of the loudspeaker array as configured and flown in the venue, and/or the specific setting changes which are desired in order to determine the smallest affected zone that includes the selected area.
