BlackHole is a modern virtual audio loopback driver for macOS that allows audio to be routed between applications with zero additional latency. It is widely used by musicians, streamers, developers, and audio engineers who need reliable internal audio routing without external hardware. BlackHole supports a wide range of sample rates and configurable channel counts, making it flexible for both simple and advanced audio workflows. The driver integrates directly with macOS Core Audio and appears in Audio MIDI Setup and supported audio applications. Designed with performance and stability in mind, BlackHole works on both Intel and Apple Silicon Macs without requiring kernel extensions or system security modifications. As an open-source project, it offers transparency, customization options, and active community-driven development.
