This paper describes the first system designed to allow children to conduct an audio and video recording of an orchestra. No prior music experience is required to control theorchestra, and the system uses an advanced algorithm totime stretch the audio in real-time at high quality and without altering the pitch. We will discuss the requirements andchallenges of designing an interface to target our particularuser group (children), followed by some system implementation details. An overview of the algorithm used for audiotime stretching will also be presented. We are currently using this technology to study and compare professional andnon-professional conducting behavior, and its implicationswhen designing new interfaces for multimedia. You’re theConductor is currently a successful exhibit at the Children’sMuseum in Boston, USA.
