About:
Apple's AU Lab is a lightweight digital audio mixing and routing application designed for testing and hosting Audio Units (AU) plugins. It provides a straightforward interface for creating signal chains, connecting audio inputs and outputs, and monitoring plugin performance. This tool is essential for developers and audio professionals who need a minimal host to validate AU plugins without launching a full DAW.
Key Features:
  • Lightweight Audio Units host for testing and validation
  • Flexible routing for inputs, outputs, and plugin chains
  • Real-time parameter automation and monitoring
  • Simple interface optimized for quick A/B testing
Use Cases:
  • Developers testing and debugging new Audio Units plugins
  • Audio engineers routing hardware inputs through AU effects for live processing
Alternatives:
  • Hosting AU – More modern UI and advanced features, but paid
  • MainStage – Apple's full-featured live performance app, much heavier resource usage
