There is an online course about Audio Signal Processing for Music Applications:
https://www.coursera.org/course/audio

In this course you will learn about audio signal processing methodologies that are specific for music and of use in real applications. You will learn to analyse, synthesize and transform sounds using the Python programming language.

Fantastic, thanks for the tip! I was looking for an excuse to learn Python (and finally drop Fortran), so this looks like a good opportunity.
