Perceptually-motivated generation of electric guitar timbres using an interactive genetic algorithm

Wilson, AD

Abstract

This paper presents a system for the interactive modification of electric guitar timbre. A genetic algorithm was used to explore the parameter space of a simplified re-amping circuit, which consisted of an initial high-pass filter, a soft-clipping circuit, equalisation and cabinet simulation. This allowed perceptually optimal solutions to be found in the parameter space, e.g. to find sounds that are “warm”, “bright”, “heavy” or any other perceptual quality, as perceived by the user. Such a system could be used to increase accessibility in music production. Additionally, it is hoped that this system can be used in future psychoacoustic experiments investigating the perception of electric guitar timbre, or that of similar instruments.
