A theory of smart loudspeaker arrays is described where a modified Fourier technique yields complex filter coefficients to determine the broad-band radiation characteristics of a uniform array of micro drive units. Beamwidth and direction are individually programmable over a 180° arc, where multiple agile and steerable beams carrying dissimilar signals can be accommodated. A novel method of stochastic filter design is also presented, which endows the directional array with diffuse radiation properties.
