Abstract
We describe a system that applies Internet concepts and software
techniques to deliver audio from source to speakers using common
computing hardware. The techniques overcome clocking and jitter
problems. Microphones built into each transducer to locate
loudspeakers allow the system to identify speaker placement,
automatically compensate for off-center listening locations, adjust
for inter-channel gain, delay, and do frequency response matching. A
research prototype demonstrates the concepts and measures the
resulting quality.
