Interesting. I'm currently in the process of building something with a audio reactive LED strip but didn't come across this project yet. The WLED [1] ESP32 firmware seems to be able to do something similar or potentially more though.

Edit: Oh wait, that project needs a PC or Raspberry PI for audio processing. WLED does everything on the ESP32.
