From where you get the info about the effects?

Hi,

As far as I can see, currently there are a few effects implemented in the visualisation file: Energy, Spectrum, Scroll, Scroll In, Scroll Quad. My question is, did you looking at some page, paper or whatever to implement those effects or you're just have deep understanding about signal analyse or something like that and you know how to do them.

Thanks :)

The visualizations are created using numpy. So the 3 visualizations that I created, I read up on the numpy documentation here: https://numpy.org/doc/

The signal analysis is done via Pyaudio which is then fed into numpy to create the visualizations. Scott Lawson gets credit for almost all of that work in his original repo: https://github.com/scottlawsonbc/audio-reactive-led-strip

my repo here just builds on his.
