"Identity SA" is an interactive and generative installation that combines a swarm- based simulation with real time camera based interaction that we presented at GA conference 2007. We extended it by embedding two methods to generate sounds and music from pre-recorded sampled sounds. One is to let agent trigger sounds at intervals that are synchronized to a particular musical rhythm. The other one is to generate sounds whose transposition and timing is purely related to the agent's properties. The probability that an agent triggers a sound is proportional to the square of its angular velocity for both cases. By mixture of these two methods, it generates a rich variety of attractive sounds that react with the visitor's motion.
