The “moids” model consists of 48 electroacoustic devices that generate sound autonomously, in accordance with certain rules. These devices, containing built-in microphones and speakers, react in response to sounds made by the audience, and by the whole environment. In this way, they create a dynamic acoustic environment in an autonomous, decentralized, and coordinated fashion. Like a chorus of singing crickets or frogs, a harmonious concert can be achieved, with each device working independently. “moids” is an non-deterministic model that creates sound instantaneously in reaction to accidental changes in the environment.
