Abstract:
A method of generating audio data comprising:(a) determining a dynamical rule set comprised of a plurality of parameters; (b) receiving input audio data respectively having a plurality of characteristics; (c) evolving a multi-state dynamical system in accordance with the dynamical rule set for T time steps, to generate synthetic audio data respectively having a plurality of characteristics, wherein said multi-state dynamical system is cellular automata, said T time steps is determined from the duration D of the input audio data and size N of the dynamical system, wherein T=D/N; (d) comparing at least one characteristic of the input audio data to at least one characteristic of the synthetic audio data, to provide a comparison result; (e) modifying at least one parameter of the dynamical rule set in response to the comparison result; and (f) repeating steps (c), (d) and (e) until a predetermined criterion is met.
