Linux Sound 2002:
Open Source Music Synthesis, Composition, and Audio Programming

instructor: Christopher Burns
resources: "http://www-ccrma.stanford.edu/workshops/linux2002/"

Course Description

The Center for Computer Research in Music and Acoustics (CCRMA) has been using the Linux operating system for music composition, synthesis, and audio DSP research since 1996. This workshop will cover the basics of sound synthesis, signal processing, and algorithimic composition, with an eye towards practical applications in the CLM and Pd programming environments, running on Linux. Additionally, the workshop will provide an overview of the most popular linux distributions, and a brief installation clinic with a specific focus on audio, midi and real-time performance.

General information

Feel free to browse through the CCRMA User's Guide which describes the available facilities and how best to use them. The document also includes a link to the FAQ (Frequently Asked Questions) about the CCRMA computing environment. A relatively new guide to applications at CCRMA (especially those running in the Linux environment) is available at Planet CCRMA.
