AES 2003 - Duran Audio presents DDC

Only three sound reinforcement companies took advantage of the new Exhibitor Seminars, all of them tellingly local. Alcons Audio's Tom Back explained ribbon transducers, understandably, while Ampco discussed active noise control. But Duran Audio really took the mouse by the clogs with a hefty analysis of digital directivity control.

Duran's proprietary Digital Directivity Control (DDC) resides in the company's Axys Intellivox speakers, but here new concepts were introduced called Digital Directivity Synthesis (DDS) and Digital Directivity Analysis (DDA). Between them, DDS and DDA can simulate almost infinite radiation patterns of an array, and provide a glimpse into the future of system design for, especially, problematic acoustic spaces.
