From this post here it says "each element shows the relative amplitude (0..1) of a the frequency equal to **N 24000 / Q* Hertz"It looks like the values represented...

Think I got it now. Using your answer and Oliviert's I think I might have it. float energy = Mathf.Pow(Mathf.Abs(fftResultBins[i] - (1f / currentFrequency)), 2);               ...

That is getting me a flat response! Thank you...I switched the code to this: (and divide the bin once full by the number of values I put in the bin.float energy...

Does it not look right because it is linear? Here it is in log. Green is fft results and blue is 1/f. (The results are better but as seen above, the graph is still...

Thanks for the quick reply! Did I understand correctly in the code below? I subtract 1/currentFrequency from each frequency that I am adding to the bins? I have...

Hello, I am making a 31 band pink noise analyzer.  I send the pink noise file through a windowed FFT. I then take the frequency data and add the values in each...
