Mapping strategies for gestural and adaptive control of digital audio effects

Abstract

This paper discusses explicit mapping strategies for gestural and adaptive control of digital audio effects. We address the problem of defining what is the control and what is the effect. We then propose a mapping strategy derived from mapping techniques used in sound synthesis. The explicit mapping strategy we developed has two levels and two layers for each level: the first level is the adaptive control with a feature combination layer and a control signal conditioning layer; the second level is the gestural control layer. We give musical examples that illustrate the interest of this strategy.
