Real-time AudioVisual Composition with RayTone

Are you interested in experimenting with sound and visuals to create an original multimedia performance? This five-day workshop offers an introduction to real-time audiovisual composition using RayTone - a node-based sequencing environment designed to promote a playful workflow for transforming creative ideas into artistic content.
The workshop is hosted by RayTone co-author Eito Murakami, an artist and engineer working in computer music and graphics. We will also welcome Professor Ge Wang as a guest lecturer to introduce ChucK - a strongly-timed music programming language. With ChucK embedded in RayTone, users can customize behaviors of audio units that perform digital signal processing at run time. Additionally, RayTone allows users to load OpenGL Shading Language (GLSL) scripts for graphics programming such that audio and visual elements can be controlled simultaneously.
The workshop is structured into three categories: an introduction to RayTone sequencing, lectures on ChucK and shader programming, and activities to design original RayTone patches. In addition to learning from instructors, attendees will exchange knowledge and collaborate with each other to develop creative ideas. Upon completion of the workshop, attendees will learn to combine digital signal processing with graphics programming to perform real-time audiovisual composition. There will be an opportunity to present an original piece using RayTone on the last day of the workshop. Prior musical and programming experience may be helpful but not required.
