Hello,

Welcome to the community!

I will not be sharing the code I wrote other than what is in the posted topics.

I wrote these from scratch each time I was asked about it by adding a few lines of code to the existing sound examples.

See this topic also:

> Hello, I was able to add a few lines of code to the Processing sound library examples and do this: Upper left is the FFT plot of amplitude (y) vs frequency (x) with color added to amplitudes for each frequency. Lower left is time (y) vs frequency (x) with color added to amplitudes for each frequency. Right side is frequency (radius) vs time (angle) with a rotating sweep of the same data from lower left plot. Time was updated each frame. I am posting this to demonstrate that…

Try doing it on your own… it is much more rewarding.
