Using the microphone is fairly straightforward in Godot, though you might not realize it since the information you need is scattered all over the web. This is my attempt to organize everything into one post. We'll look at how to record, play back, and save audio in addition to how we can performa real-time analysis of the volume and frequency of the microphone input.
