A Particle-based Fuzzy Logic Approach to Sound Synthesis
Rodrigo F. Cádiz, Gary S. Kendall · Research Portal (Queen's University Belfast) · 2005
This article describes a novel audio synthesis technique based on sound particles, behavioral rules and fuzzy logic. Our approach borrows ideas from many-body classical physics, quantum mechanics, multi-agent and complex systems. The technique allows the creation of highly complex sonic behavior by very simple means, using the idea of a sound particle as its point of departure. Each sound particle in the system possesses several fuzzy properties, such as frequency, intensity and charge. These properties are used as inputs to a rule-based fuzzy logic inference system that controls the temporal evolution (trajectories) of the particles and the interactions between them. The rules are easy to elaborate, modify and adjust, because they resemble human reasoning and require no knowledge of the mathematical or physical nature of the trajectories or the interactions. The main objective of the proposed synthesis technique is to provide an intuitive, easy to use and flexible interface to the creation of very complex sonic phenomena.
