Alright. I’m a grad student in music composition and have been learning Max/MSP over the last year. One of the professors that I’ve been working with has begun to take me back through the basics of digital signal processing, so that I can understand more of the nitty-gritty of what’s going on beneaths my Max/MSP experiments.
As would be expected, our studies have brought us upon the DFT and FFT. I am completely stuck and am just not understanding how they work. I can explain very well what takes place when these transforms are used. I guess my issue is that I understand how they work and how they are implemented, but I don’t understand the mathematics behind them. I went up through AP Trig/Precalc in high school (10 years ago), but I haven’t had any math courses since. I understand a good deal of the math in the DFT/FFT, but if you don’t understand it all, you sort oof don’t understand any of it…know what I mean?
So, I guess I’m looking for suggestions on how to proceed. My professor “doesn’t know how to teach it to me” (his words, not mine), and I am the type of person who desperately wants to understand. Do I need to go to a certain math text(s) to review? Is there a better DFT/FFT introduction out there (so far I’ve been using Dick Moore’s and Miller Puckette’s)? What to do?
Thanks for your help,

To really get to grips with how the (D)FT works, you’ll need to
The best explanation of the DFT I’ve come across is ‘Understanding
However, it really depends on what it is that you wish to understand how

I really appreciate the suggestion. Sorry it’s taken me a while to respond!
