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.
