Multiple moving sound source tracking using PSO

In this paper, we propose a multiple sound source tracking method using Particle Swarm Optimization (PSO), and show its performance in an actual room environment. In this method, directions of arrivals (DOAs) of the received signals are estimated by searching peak-point of the MUltiple SIgnal Classification (MUSIC) spectrums using PSO. Several results of the experiments in an actual room environment show the effectiveness of the proposed method.
