Audio Router is a lightweight Windows utility designed to redirect the sound output of individual applications to distinct audio devices in real time, eliminating the need for multiple physical sound cards or manual cable switching. Classified under Audio Enhancement & Routing Software, the program intercepts the audio stream of any running process and transparently remaps it to a chosen playback endpoint—such as headphones, external speakers, a virtual cable, or a USB DAC—while leaving the system default untouched. Typical use cases include sending a voice-chat client to a headset, streaming game audio to a capture card, isolating music production software on studio monitors, or simultaneously recording separate application tracks for podcast production. Version 0.10.2, the first and current public release published by audiorouterdev, exposes a minimal tray interface where users can create per-application rules, toggle them on the fly, and monitor active routings through color-coded indicators; no kernel drivers are installed, so the tool remains portable and reversible. Because the engine operates at the WASAPI level, latency stays below 20 ms on most Windows 10/11 configurations, and volume sliders within the utility can further attenuate or boost each stream independently. The single 2 MB executable runs on x86 and x64 systems without elevation, stores its INI configuration alongside the binary, and automatically reapplies mappings after reboot. Audio Router is available for free on get.nero.com; downloads are served through trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
