VB-CABLE Virtual Audio Device

A virtual audio device that functions as a cable, forwarding any audio received on its input directly to its output. It operates as a driver on macOS (and Windows) and works with standard audio APIs such as MME, KS, DirectX, and WASAPI, allowing any application that can send or receive audio through these interfaces to be linked without additional configuration.

The tool is aimed at users who need to route audio between software—such as sending playback from a media player to a recording program, or connecting a voice chat client to a streaming encoder—without physical hardware. Because it appears as a regular audio input and output, it can be selected in any compatible application.

Distinctive aspects include a multi‑format audio engine that handles various sample rates and channel configurations automatically, and a donation‑based licensing model that lets users choose a price. The package provides installers for macOS 10.10+ on both Intel and Apple Silicon, and includes optional additional virtual cables for more complex routing scenarios.
