Music-reactive DMX experiment with an ENTTEC OpenDMX (USB to DMX interface) using the pyftdi and aubio libraries. This code is designed to run on a Raspberry Pi 4 but will also run on more powerful x86 machines. I personally use an affordable (~$35) clone of the ENTTEC OpenDMX which I found on eBay, simply search your favorite merchant website for "OpenDMX" to find options.
# On MacOS, install required libraries
brew install --build-from-source libusb
# On Ubuntu or Raspbian, install required libraries
sudo apt-get install libportaudio2
# Install required Python packages
pip3 install pyftdi numpy sounddevice aubio
The dmx.py source file contains reusable code to interface with DMX devices using an OpenDMX FTDI interface.
The anim_beatdetect.py script contains my own code to animate lights based on beat detection, which you can take inspiration from.
