Before we start trying to record different streams of audio, it's helpful to understand a bit about I/O routing. As I mentioned in last week's email, "I/O" stands for "Input/Output." The actual I/O routing determines how each piece of software connects with different audio signals. Some signals - like that from the microphone - flow "into" the app, while anything that is broadcast from the app is flowing "out." While this may seem like a simple concept, it can get a bit confusing when we start sending the output from one app to another.
