[music-dsp] Mathematical prereqs?

[Andreas Falley]

Hi -

I'm rededicating myself to the field of formal DSP study and I am 
wondering what the best math courses that serve as a prereq for fully 
understanding DSP are outside of what one might find in a standard 
Computer Science degree ( two semesters of Calc, Linear Algebra, 2 
semesters of Discrete Math). I audited a wonderful music/computer 
science course on audio DSP (as a musician) long before I took all those 
math courses and consequently know about the concepts involved behind 
the equations, but now would like to gain more exposure to that working 
level of mathematical understanding after being too distracted by a more 
mundane and long-since-inspiring web programming career path.

Thank you very much.
