We present a population of autonomous agents that exist within a sonic eco-system derived from real-time analysis of live audio. In this system, entitled Coming Together: Shoals, agents search for food consisting of CataRT unit analyses, which, when found, are consumed through granulation. Individual agents are initialised with random synthesis parameters, but communicate these parameters to agents in local neighborhoods. Agents form social networks, and converge their parameters within these networks, thereby creating unified grain streams. Separate gestures thus emerge through the self-organisation of the population.
