Machine Tongues XVI: Genetic Algorithms and Their Application to FM Matching Synthesis

Abstract

Historically, frequency modulation (FM) synthesis has required trial and error to create emulations of natural sounds. This article presents a genetic-algorithm-based technique which determines optimized parameters for reconstruction through FM synthesis of a sound having harmonic partials. We obtain the best results by using invariant modulation indices and a multiple carrier formant FM synthesis model. We present our results along with extensions and generalizations of the technique.
