If you have ever experienced an audio feedback problem on Skype due to someone not using headphones and having the laptop screen angled too far forward, you will be familiar with how hard it is to talk normally with that happening. Most other solutions I’ve read about and tried to this problem are rather imperfect, because they result in a delayed version of your voice coming back through your headphones.
The instructions here are subject to change over time. That means I need to record from two things: (1) my microphone and (2) a “what you hear” sort of audio device that lets me send my computer’s sound to some other program. This page is my attempt to formalize the best solutions I recently found for this problem on Mac and Windows. For example, because I’m a computer music researcher, I will often be in a meeting over Skype and need to be able to demonstrate audio on my system for the person I’m talking to. I’ve had a long-standing problem in my work: the need to be able to record from multiple devices simultaneously on a laptop.
