# Virtual Audio and Video Routing

**Virtual Audio and Video Routing** is the technique of using software-defined "virtual" devices to redirect media streams between applications. Instead of relying on physical hardware inputs and outputs, virtual drivers create a software bridge.

### Key Implementations in Digital Teaching
- **Virtual Cameras**: Using tools like [[obs-virtualcam]], a complex scene produced in a production suite can be "routed" into a web conferencing tool as if it were a physical webcam.
- **Virtual Audio Cables**: Using tools like [[vb-cable]], audio output from one application can be routed as the input (microphone) for another, allowing for the seamless sharing of high-quality system audio in a live session.

This approach is essential for professional-grade [[hybridveranstaltung]] and [[livestreaming]] where a simple webcam and microphone are insufficient.
