AV: Electronic Versus Physical: An Analysis Of Shaping Array Directivity

Pro Sound Web: Modifying the directivity characteristics of loudspeaker arrays through electronic delay has become increasingly popular. Whereas 20 years ago the only option was expensive dedicated digital delay units, and a few years later the original BSS Omnidrive was a luxury, the advent of inexpensive digital processing has changed the game. The design of complex arrays using a relatively high number of processing channels, as required to electronically modify the directionality of an array, is now affordable and widely implemented.
