Résumé
In this paper we introduce a system in which a cellular automaton is employed to control the evolution of synthesised complex sounds. One of the most interesting sound synthesis techniques available to musicians today is the granular synthesis technique. This technique involves the production of thousands of tiny sound granules (e.g. 35 milliseconds long) that combine to form complex and dynamic sounds. The main difficulty with granular synthesis is the specification of the nature of each sonic granule and how it will affect the overall result. Traditionally, granular synthesis systems have used probabilistic methods to control this. In this paper we describe an alternative method based on cellular automata. Our method has proved to produce sounds of a noticeably better quality than probabilistic methods in terms of the dynamics of unfolding and the naturalness of the overall form.
