Schedule

Below is the schedule of weekly in-class presentations, with pointers to all associated reading, lecture overheads, and so on. The default weekly topic is learning the FAUST language for signal processing. Additional topics will be driven by the interests, projects, and research activities of the participants. Results and associated pointers will be logged here.

• Week 1: General discussion of goals, and introduction to the default weekly lecture topic: Introduction to the Faust Language for Audio Signal Processing
  • Read ``MUS420B Administrative Info'' (this document)
  • Read ``Audio Signal Processing in Faust'' up to the section on ``Term Rewriting''
  • Download and compile the FAUST compiler.
  • Briefly look over ``Faust Tutorial''
  • Briefly look over ``Faust Quick Reference''

• Week 2
  • Features of the FAUST language, following ``Audio Signal Processing in Faust''
