I have an 4x4x4 LED cube with an ESP8266, so it has wifi and can communicate with websockets. Now I'd like to send the amplitude of certain frequencies to the cube in real time so it can show the spectrum in a colorful way...
I don't know where to begin as I couldn't find any open source addons for foobar2k to get inspired by that do kind of the thing I want.
Do you know any open source code that might help me or know of the right google search terms I have to look for? I was looking for a DSP tutorial/example but it just contained a few things and didn't go in depth especially because I know nothing about foobar2k development yet.
Any help would be greatly appreciated!
