this is my first post on here! I am trying to make my raspberry pi 3 a bluetooth speaker which synchronizes beat of the music being played from a phone to an LED light strip. For the LED light synchronization I have made a python script that uses PyAudio and AudioOp packages to do analysis on the audio input stream.
Right now, I am able to play music to the 3.5mm headphone jack of the raspberry pi 3 from my phone over bluetooth with no problem. However, my issue is creating an input source for PyAudio to recognize and read the incoming audio. I read into creating audio loop backs and virtual audio cables but I am a bit lost on the subject and I am not sure that is the right approach. Below are the established audio playback and capture devices when the raspberry pi boots up without any modification on my part.

I appreciate any guidance you may have for me to solve this problem.
