just to start with, the fftsize has to be a multiple of 2, so 2500 is not an optimal size. It should be 2048 (pow(2,11)) or 4096 (pow(2,12)) or 1024 (pow(2,10))... although you can still use any size, it's better to use a power of two, which in chuck is Math.pow(2,n) where n is the number you are rising 2 to. A good size is 2048, so n=10. Otherwise the code does not make sense... for instance FFT_SIZE/8. That only makes sense if FFT_SIZE is a power of 8 which in turn is a power of 2 (2^3=8).
2009/4/20 Andrew C. Smith <acsmith@willamette.edu>Sort of an OT question--
Where did you find this ChucK folder and is there more?
The file is stored in this directory; http://www.lullcec.org/chuck/fft/ going up another level brings us here; http://www.lullcec.org/chuck/
There's one tutorial in there written by Eduard Aylon, maybe he did the rest as well. Not at all a bad resource if you're looking for things to learn from.
Yours,
Kas.
