Abstract

A sound system includes a plurality of computing systems distributed within a performance area. Each computing system includes a speaker, and a processor. The processor oversees audio data being played as sound on the speaker. A controller provides coordination of the performance of the audio data on the computing systems. Audio effects are achieved by varying timing and/or content of audio data played as sound on the speakers as overseen by the processor within each computing system.
