1. A system for performing acoustic zooming comprising:
a plurality of beamformers generating a plurality of beamformer signals corresponding to a plurality of tiles of a video content associated with a plurality of acoustic signals, wherein each of the beamformers is directed to a center of each of the tiles; and
a target enhancer
identifying tiles having at least portions that are included in a zoom area of the video content,
selecting the beamformer signals corresponding to the identified tiles, and
combining the selected beamformer signals to generate a target enhanced signal associated with the zoom area.
