| Use Case | How It Works | |----------|---------------| | | Send game audio to VB-Cable; OBS adds it as a mic source. | | Podcasting / Voice Chat | Play soundboard or music into VB-Cable; Discord uses it as microphone. | | Loopback Recording | Record streaming audio (Spotify, YouTube) into Audacity without stereo mix. | | Multi-application monitoring | Send multiple apps to different cables for independent volume control. |

In a typical Windows environment, audio flows from an application (e.g., Spotify) to a physical output (e.g., speakers). Simultaneously, a microphone sends audio to an application (e.g., Discord). However, routing audio between applications—such as playing a game’s sound into a voice chat as background music—requires a virtual connection.

VB-Cable solves this by implementing a . It simulates a "virtual wire" inside the computer, allowing for bit-perfect digital audio transfer between software programs with negligible latency.

VB-Audio Virtual Cable (VB-CABLE) is a popular virtual audio device driver for Windows and macOS that acts as a digital patch cord between applications.
