DATT3070 Creative Generative Audio Signal Processing

+

Wednesdays, 3pm-6pm, Fall 2024, Fine Arts building room ACW 103

+

Instructor: Graham Wakefield grrrwaaa a t york u do t ca

+

Hello and welcome!

+

This course is about the astonishing things you can do—and the insights you can find—when you work at the atomic sample-by-sample structure of digital audio. The course focuses on creative exploration of algorithmic and generative sonic signal processing with a special emphasis on “working at the sample level” in real-time/interactive contexts. This means working at the lowest level of time-domain digital audio signals, as is made possible through a software called gen~, that is part of Cycling '74's Max and RNBO. These tools that are widely used for prototyping in artistic and industrial settings including audio software & hardware design, music production, game audio, sonic arts, and other broader contexts.

+

The course follows the structure of the textbook “Generating Sound & Organizing Time”, Wakefield G. and Taylor, G. Cycling ’74, October 2021. ISBN-10: 1732590311 / ISBN-13: 978-1732590311

+

Starting from the simplest beginnings we’ll see how very many seemingly unrelated synthesis and sound processing algorithms come down to a pretty small number of common circuits and useful patterns to think with, that can be reapplied in many different ways to bring new musical signal processes to life.

+

For clarification: this is not a course about music composition, performance, or studio production as such; nor is it a course in mathematics and engineering for digital signal processing. No background in music theory, mathematics or computer science beyond high school levels are assumed. The curriculum is primarily practice-based: problem-driven and technique-focused leading toward applications that you can utilize in other project-based courses, research, compositions, and artworks.
