In/Finite is a live performance software system implementing audio feedback networks with complex adaptation mechanisms inspired by processes found in organic composting and aerobic biodegradation. The system, implemented in the Faust programming language, originated from a commission for an autonomous sound installation as part of the Waste Kompost Radio project; later, we extended it into a more advanced system and deployed it in live performance with human-machine interaction. Drawing inspiration from the three main families of organisms in biodegradation, we rendered a similar configuration in the audio domain as three groups of signal processes performing sonic decomposition: granular resampling, allpass diffusion, and filtering. Each of the three DSP families includes four interdependent adaptive agents, and the families are interconnected via a time-variant matrix through which they exchange energy and information. While nested control mechanisms ensure stability and self-oscillation, the system’s overall behaviour is influenced by a global energy metric. This metric, analogous to temperature in the biological model, determines the activity and survival rate of the DSP families. We believe that the system produces compelling sonorities and musical forms with or without human intervention, exhibiting complex emergent behaviours across multiple time scales.
