The work described in this paper concerns development of a specialized signal processing architecture, targeted for VLSI implementation, which would make a loudspeaker array with digital directively control practicable. The solution presented here utilizes a specialized array element signal processor to provide the signal processing capabilities required at each loudspeaker array element. Block diagrams of the array element signal processor and the user control interface are presented along with the overall system organization.
