Depending on the context, Audio Router refers either to a specific open-source Windows utility developed by audiorouterdev, a general concept in sound engineering, or a mobile streaming application. The breakdown below covers each variation. 1. The Windows Software (“Audio Router” by audiorouterdev)
The most common reference is an open-source Windows utility hosted on GitHub. It was built to solve a specific limitation in older versions of Windows: the inability to send different apps’ sound to different audio devices simultaneously.
Core Purpose: It allows you to route audio from specific individual applications to different audio outputs. For example, you can route Spotify to your desktop speakers while routing Discord voice chat to your headset.
Audio Muting & Volume Control: You can independently control the volume or completely mute individual apps from a single panel.
Audio Duplication: A standout feature that allows you to duplicate an application’s audio stream so it plays through two different output devices at the same time.
Current Status: The original software is widely considered legacy software. Microsoft added native per-app audio routing directly into the Windows ⁄11 Settings panel (under Settings > System > Sound > Volume Mixer), making the tool largely redundant for basic tasks. 2. General Concept (Audio Routing)
In professional audio production, live sound, and broadcasting, an audio router is either a piece of hardware or software that manages signal flow. An Open Plea to Apple: Give Us Real Audio Routing on macOS
