device routing

Device routing in Windows refers to the ability to direct audio output from individual applications to specific playback devices, such as speakers, headphones, or headsets. The EarTrumpet tool, a modern tray mixer for Windows, provides per-app device routing directly from the system tray, allowing users to assign different audio outputs to different apps without navigating fragmented system settings. This feature is particularly useful for power users who want to route game audio to a headset while keeping music on speakers, or manage multiple audio devices simultaneously. EarTrumpet simplifies this process with per-app sliders and hotkeys, offering a more intuitive alternative to the native Windows audio controls.
