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
