About:
BlackHole is a modern macOS virtual audio driver that allows applications to pass audio between each other. It creates a virtual bus for routing audio from any application to any other application without needing physical cables. This enables complex audio workflows for recording, streaming, and processing entirely in software.
Key Features:
  • Zero-latency virtual audio routing
  • Multi-channel support (up to 64 channels)
  • Zero CPU overhead when idle
  • Compatible with Core Audio and popular DAWs
Use Cases:
  • Recording system audio directly into DAWs or audio editors
  • Creating virtual audio cables for streaming and screen recording
  • Routing audio between different applications for processing
Alternatives:
  • Loopback – Commercial alternative with GUI but costs $99
  • Soundflower – Legacy solution, no longer actively maintained
