Have you ever wondered what a cellular automaton would sound like? This Demonstration converts cellular automata to sound using granular synthesis and a set of harmonically related frequencies. Each row of the automata is represented as one granule of sound consisting of superimposed sine waves whose frequencies are determined by the relative positions of values in the row. The set of possible frequencies is determined in this case by using Farey sequences and an arbitrary base frequency. This Demonstration explores the 3-color range 2 totalistic rule space, chosen for its bountiful variety of complexity.
