hoped to create a sound using a new technique, rather than by a
combination of waveforms, such as a sinusoidal wave. In addition,
I also wanted the sound to continue to change eternally.
Automate-ON is based on the principle of a complex change in sound
waveforms based on a predetermined simple rule. Each element of
waveform data in a certain interval has an amplitude discretized
as 1, 0, or -1. For individual elements, the next amplitude is
determined based on a rule established using the amplitudes of
neighboring data and that of the element, as done in
one-dimensional cellular automaton. For example, when the
amplitudes of the element and those to its left and right are 0,
1, and -1, respectively, the amplitude of the next element will be
1. This rule is intended to produce chaos with no periodicity.
Using one-dimensional cellular automaton, 8 patterns are available
using 2 values (0 and 1), while the new method allows 27 patterns
to be formed.
