This is an introduction to audio synthesis, both in theory and in
practice, using Pd (Pure Data) as a platform.
Pd is free and you can run it on Windows, Linux, or Mac OSX.

There are eight weekly assignments, due Fridays.
The exam (3-6PM, Tuesday, March 20) is a final project presentation. Assignments are worth 10 points apiece and the final is worth 20.
Patches from class will gather on
