That is very nice. I've been looking for something like this. It's useful in the case where you want to do a tutorial with an application that produces sound, but you want to talk at the same time. The best solution before would be to plug a 3.5mm cable into an audio interface that accepts this sort of input, and then record at the same time. The problem is that then you cannot do small cuts in real-time as easily as if you are recording directly into a DAW with audacity, and plus it gives you the possibility of using real-time effects with your DAW.
Good for streaming also, without needing to use OBS, which is hit and miss when it comes to some things.
