About:
Proxy Audio Device creates virtual audio drivers on macOS that redirect audio to physical output devices. It solves the problem of applications that lack native audio output selection by providing a system-level proxy. This enables advanced audio routing scenarios without requiring complex audio driver modifications.
Key Features:
  • Virtual audio device creation
  • Automatic audio redirection
  • No kernel extension required
  • Low latency audio processing
  • Simple menu bar interface
Use Cases:
  • Routing audio from specific applications to different speakers
  • Creating aggregate audio devices for multi-output setups
  • Fixing apps that ignore system audio settings
  • Screen recording with isolated audio sources
Alternatives:
  • Soundflower – Legacy solution with kernel extensions, less stable on modern macOS
  • BlackHole – Modern alternative with similar functionality, requires more manual configuration
  • Loopback – Commercial solution with GUI, more features but paid
