Today's vast amount of streaming and video conferencing on the Internet lacks one aspect of musical fun and that's what this course is about: high-quality, near-synchronous musical collaboration. Under the right conditions, the Internet can be used for ultra-low-latency, uncompressed sound transmission. The course teaches open-source (free) techniques for setting up city-to-city studio-to-studio audio links. Distributed rehearsing, production and split ensemble concerts are the goal. Setting up such links and debugging them requires knowledge of network protocols, network audio issues, mics, monitors and some ear training.

The one-semester course has two streams: 7 in-class lectures alternating with 6 hands-on online weekly sections for learning and practicing the basics. Toward the end of the semester, the focus is on 3 weeks of projects and advanced topics. The initial online course materials cover fundamentals and getting started. Bi-weekly in-class meetings throughout the semester will provide tips on software installation, testing, readings and offer related tutorials. We'll survey the history of the field and move on to discussions of emerging low-latency collaboration technologies involving video, GPS-sync and audio prediction. Recent doctoral dissertations will be presented. End-of-term culminating projects chosen by students can be live performances with remote partners, recorded work or technical contributions for online collaboration.
