Abstract
The following paper presents a system for creating real-time visuals based on multiple simultaneous vocal inputs. The goal of this work is to augment live musical performances by visually conveying the spirit and structure of the piece. Using the Processing programming language, sounds are analyzed and return pitch and amplitude as numerical values. Visuals representing pitch and amplitude for each of the musicians are created in real-time and are projected concurrently with the live musical performance. This process is demonstrated by work presented here with a professional 8-voice ensemble. As part of this project, a library of functions is being created and shared to allow others to implement similar productions.
