I am trying to setup this audio-reactive-led-strip library but with Bluetooth audio as the input. I have so far, got my LED strip to work with the standard strandtest.py and have also successfully setup Bluetooth audio to play on the Pi (I have it outputting through the 3.5mm audio jack).

Now, it states on the audio-reactive documentation that it supports a "virtual audio device" and as such I believe I need to set it to listen to a Bluetooth virtual audio device, but I am unsure of how to go about this - https://github.com/scottlawsonbc/audio-reactive-led-strip#virtual-audio-source.

Here is my current output from running said library's script:

pi@raspberrypi:~ $ sudo python audio-reactive-led-strip/python/visualization.py
