Today I learned that less is more when using the noise. So instead of manipulating as much parameters as possible I was focussed on creating repeatable visual effects - the same sound creates exactly the same animation again and again.
To me it appears way more hypnotic that way. You really see the music now!
The spectrum analyzer window is just my debugging helper to see what is going on with the incoming data. Way more convenient than starring at the serial monitor.
P.S. I filmed it alreday with 60 fps but it is still not enough… live it looks more punchy.
