BlackHole is a modern macOS virtual audio loopback driver that lets applications pass audio to other applications with zero additional latency. It is built as a userspace Core Audio driver requiring no kernel extensions, with configurable channel counts and sample rates.
Use cases
- route audio from one mac app to another
- record system audio on macOS
- capture Zoom or Meet audio for transcription
- send DAW output to streaming software like OBS
- create a virtual audio cable between apps
- screen recording with internal audio
When to choose
- you need app-to-app audio routing on macOS with no added latency
- you want a driver without kernel extension or security changes
- you need high channel counts or high sample rates for professional audio
When to avoid
- you are on Linux or Windows
- you need audio mixing or effects, not just pass-through
- you need a graphical routing interface
