Where: Hallgarten Hall, Seminar Room When: W/F 10:00-12:00 What: This seminar covers topics in sound analysis, synthesis and digital signal processing from theoretical, mathematical, and practical perspectives. Topics include important ideas in the history of digital and analog synthesis, and will draw on classical models as well as current and future techniques. Standard and speculative algorithms for digital sound processing will be analyzed in depth. Students will realize many of these ideas in a variety of digital music environments.
