220b: Synthesis Techniques, Compositional Algorithms, Psychoacoustics and Spatial Processing

* Course Description

This is the second course in the 220 series. It covers some basic sound synthesis techniques not covered last quarter (see 220a), algorithmic composition techniques, spatialization and some psychoacoustics. The course uses the CLM-2 (Common Lisp Music) environment to create all sound examples and the Common Lisp programming language (in which clm-2 itself is implemented) for all programming examples.

Common Lisp Music (CLM) is a public domain sound design language written on top of Common Lisp, currently running in Macintosh PowerPCs, Windows and several UNIX environments including SGI, Sun, NeXT and Linux.

Evaluation consists of 4 assignments and a final project. Each assignment builds on the knowledge of the previous one, and the final outcome is a final project which is usually a computer music composition. This project is going to be presented during the finals week.
