Abstract

This paper describes the design, implementation, and application of an audio-driven computer-based system for live and interactive performance with an orchestra. We begin by describing the compositional and musical goals, emphasizing the electronics aspect. We then discuss the challenges of working with an orchestra and integrating the electronics in a concert hall. We describe the hardware setup and then detail the software implementation, from audio analysis and “perceptual parameter” estimation to the generative algorithm.
