SRC-XYZ  
                       
                       
    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.
