    A PC based sound source location system has been implemented at CAIP. The system consists of an 8 channel AT&T DSP32C based Signalogic DSP board and a host PC. Eight electret microphones are used to capture audio signals that are digitized by the DSP board. A computer-directed video camera is automatically pointed at the sound source. The audio is captured by a beamforming line array. The system operates in real time, and its components cost approximately USD$9000. It performs in a robust fashion and may be installed in a less than an hour. A detailed description of this system is given in (Rabinkin, 1996) and (Rabinkin, 1996b
