FracWave produces sounds with dynamic characteristics by means of a parametric control of simple non-linear maps. It is a compositional tool which allows a composer to generate new sounds and to build up sonic structures from an atomic level. This paper discusses the basic concepts about FracWave, it elucidates how the model was derived from recent research on non-linear dynamics, it presents a compositional approach based on parametric scores, and it ilustrates the musical results presenting graphics and sound examples taken from compositions created by the author using FracWave.
