Smart directional and diffuse digital loudspeaker arrays
Abstract- A theory of smart loudspeaker arrays is described where a modified Fourier technique yields complex filter coefficients to determine the broadband radiation characteristics of a uniform array of micro drive units. Beam width and direction are individually programmable over a 180-degree arc...
