AuVi: An Audio/Visual Performance Application.
The Problems of and the Solution to Audio/Visual Synchronization in Live Performance.

This essay constitutes the theoretical portion of my PhD at the University of Chicago (Minor Field Paper). The paper addresses the issues involved in the synchronization of live instruments, electronics and video, with a special emphasis on the freedom and flexibility inherent to live performance. The third chapter is a guide to AuVi, an application written in the Max/MSP/Jitter programming environment and created for my composition Eppur Si Muove for chamber ensemble, live and prerecorded electronics and video. Since then, AuVi has been used during a number of concerts, assisting the performances of pieces for various combinations of live instruments with multi-channel audio and/or video. The simplicity of the user interface makes it a very flexible and useful performance tool. The video engine of AuVi uses Jitter, but the software can be used in audio mode only as well, without Jitter installed. This version of AuVi uses a 4 channel output. I have plans to create an 8 channel version with some additional improvements. Stay tuned! Comments welcome!
