What is AppAudioRouter?

Windows itself lets a program play to one output at a time. App Audio Router lifts that: pick a program, pick one or more playback devices, and its audio goes to all of them at once — live, without restarting it — or into another program's input, so Discord can hear Spotify the way a microphone would. Everything is done with the Windows Core Audio API from a single native binary: no helper executable, and no driver bundled or installed for routing (feeding another program runs through a loopback endpoint pair you install and pick once in Settings).
