Audio Network-Based Massive Multichannel Loudspeaker System for Flexible Use in Spatial Audio Research

In order to provide a flexible means for exploring various spatial audio algorithms in sound field synthesis, a massive multichannel system consisting of an array of 640 loudspeakers was created. It is based on an audio network that distributes discrete audio signals to a grid of amplifiers. Given the massive size of the loudspeaker array, special means for configuring, routing, control, reliability, flexibility, redundancy, economics, and cabling had to be developed. The resulting system should prove to be a powerful tool for research various presentation formats.
