Non-standard Sound Synthesis with L-systems (LMJ19)

Leonardo Music Journal, MIT Press, issue 19, December 2009

ABSTRACT:
This paper presents a new non-standard technique for waveform synthesis in the time domain using Lindenmayer system (L-systems), a formalism related to grammars, fractals and automata. This technique, developed as part of a larger-scale compositional system, is based on waveform segmentation and offers various methods for generating wavetables. The paper first introduces L-systems and some specifics of their interpretation and discusses extensions such as incorporating genetic algorithms and designing hierarchical L-systems and L-system networks. The second half describes the implementation model in detail, proposes some sound synthesis strategies and presents paths for further work.

Undercover Harpsichord Agents Terrorize the Court

An electroacoustic tape piece, whose sound material consists of transformations of harpsichord recordings performed by the composer. This material is processed using a complex hierarchical network of Lindenmayer Systems and Genetic Algorithms – an algorithmic model of organic growth.
