|SRC-XYZ is an audio source
location detection system by triangulating distributed microphones.
It is composed of nodes that include a set of four microphones at 90
degree spaced angles, and software that performs a basic analysis of
amplitude of microphone input levels to determine audio source direction
relative to the other nodes. Three nodes communicate to each other
through radio signals. One of the nodes is a base station that transmits
the collected data to a computer.
