Day 27

Another day, another experiment. I tried to resurrect my Spectral Flatness code and I think it is a precision error in the geometric mean. I thought about scaling the FFT values but I will have to go back on the math for that to make sure I don't skew the values the wrong way. For now I have used the arithmetic mean of the spectrum to give me some numbers to play with.

This sketch changes colour at different volumes, currently white for quiet and black for loud, and becomes more animated with noisier spectra (not really but close enough for now). I think I am getting close to something interesting. Maybe once I sleep on it tomorrow will show me the answer.
