Many games lack a simple built-in option to mute audio when you Alt-Tab or minimize the window. I haven't found any solution that fits my use-case, so i made one for me. It's a tiny, open-source background utility that hooks into the Windows Audio Session API (WASAPI) to cleanly control game audio based on window focus. It can be used for regular apps as well.
