Real-Time A/V Systems introduces students to the history, theory and practice of live audio/visual signal processing, so they may incorporate “#realtime” strategies in their individual art-making. The course begins with building basic, hardware-based, analog A/V mixing systems, as well as work with SAIC’s historic Sandin Image Processor. Notions of chance & experimentation are explored as we look at early video art & electronic music pioneers such as Nam June Paik, John Cage, Phil Morton and others. We look closely at Chicago’s own #realtime & Dirty New Media scenes, and enjoy visits from contemporary artists (in-person and via the Internet). As the semester progresses, we move to digital signal processing and software-based systems, covering VDMX, Max/MSP/Jitter, Arduino, and other open-source tools.
