Abstract

We report on the development of a video based analysis system that controls concatenative sound synthesis and sound spatialisation in realtime during concerts.

The system has been used in several performances, most recently Transformation for electric violin and live electronics, where the performer controls the sound synthesis and spatialisation while moving on stage.
