FFT condensing?
Jun 2nd, 2010, 8:21pm  
Hey all. I just started programming with Processing (but am not new to Java) and had a question about FFT.

Is it possible to look at the averages of the bands. It's a bit confusing to explain so I'll just run a sample below:

Band 0: 3
Band 1: 5
Band 2: 4
Band 3: 9
Band 4: 7
Band 5: 8

So if I want the averages of Band's 0, 1 and 2 It would return 4. But I also want the averages of Band's 3, 4 and 5 (which would be 8.) Is this possible to do and if so how?

I want to do this so that instead of running through the entire FFT using for(int i = 0; i < fft.specSize(); i++) I instead only have say 50 values which are the averages of 0, 1 and 2/3,4 and 5/6,7 and 8/etc.

Thanks in advance!
