ESCHER-modeling and performing composed instruments in real-time

Abstract

This article presents ESCHER, a sound synthesis environment based on Ircam's real-time audio environment jMax. ESCHER is a modular system providing synthesis-independent prototyping of gesturally-controlled instruments by means of parameter interpolation. The system divides into two components: gestural controller and synthesis engine. Mapping between components takes place on two independent levels, coupled by an intermediate abstract parameter layer. This separation allows a flexible choice of controllers and/or sound synthesis methods.
