The ability to change your microphone input and general audio settings for each game.
For example when playing a VR game so it takes the microphone you have on your VR headset instead of the mic you use at your desktop. It happens alot that i clip something and forget to switch back to my active mic after a VR session (or the other way around) and i end up without my mic audio.
Another good example is to adjust what channels you want to have in your recording when playing certain games.
