This is the companion repo for a Medium tutorial post on integrating PyAudio and PySimpleGUI.
For a step by step that covers things like a simple PyAudio Blocking and non blocking microphone example consult the post:
Integrating PyAudio & PySimpleGUI
This repo is just the gists used in repo form, the final script if you just want to copy/pasta or check it out is Microphone_listener.py
Cheers !
