Abstract

In the 1980s, wave field synthesis (WFS) was proposed by Berkhout [J. Audio Eng. Soc., 36, pp. 977–995 (1988)] as a new and powerful concept for spatial reproduction of sound fields without sweet‐spot‐limitations. Based on this concept, with implementation of simplifications not deteriorating the perceptual quality, a system for variable acoustics was developed: acoustic control system (ACS). The system has been widely applied as a solution for multipurpose halls. Until now, ACS processors have been built using analog electronic technology. Recently, however, a digital module has been designed that not only enables us to generate the ACS reflection patterns, but also to perform true WFS, e.g., for direct sound reinforcement with preservation of natural spatial properties. In the paper, design and specifications of the module will be discussed. Also, the potentials of integrated application of WFS and variable acoustics will be explained.
