Cellular Automata Sound Synthesis with an Extended Version of the Multitype Voter Model

In this paper we report on the synthesis of sounds with cellular automata (CA), specifically with an extended version of the multitype voter model (MVM). Our mapping process is based on DSP analysis of automata evolutions and consists in mapping CA histograms onto sound spectrograms. This mapping allows a flexible sound design process but due to the non-deterministic nature of the MVM such a process acquires its maximum potential after the CA run is finished. Our extended version model presents a high degree of predictability and controllability making the system suitable for an in-advance sound design process with all the advantages that this entails, such as real-time possibilities and performance applications. This research focuses on the synthesis of damped sounds.
