To use Audio Toolbox, you can refer to the session "Enhance your spatial computing app with RealityKit audio" from WWDC 2024. This session provides detailed steps on how to configure and use audio units within RealityKit. Here are some key points:
- Instantiate the Audio Unit: Create an instance of the audio unit you want to use.
- Prepare Configuration: Set up the configuration for the audio generator controller.
- Create Output Format: Define the format for the output of the audio unit and set it on the audio unit's output bus.
- Allocate Render Resources: Allocate the necessary render resources for the audio unit.
- Capture Render Block: Capture the audio unit's internal render block.
- Configure Audio Generator Controller: Use the audio generator configuration to set up the audio generator controller.
- Call Render Block: Call the audio unit's internal render block on the audio data provided in the audio generator's callback.
For a more detailed walkthrough, you can watch the session Enhance your spatial computing app with RealityKit audio (09:37).
Additionally, if you are interested in real-time processing and using machine learning with audio units, the session "Support real-time ML inference on the CPU" covers how to create an audio unit project that adopts BNNS graph for real-time audio processing. You can start with the chapter on Real-time processing (06:47).
