Real-Time Rendering with AVAudioEngine
summary
The talk explains how iOS 13 added AVAudioSinkNode and AVAudioSourceNode to AVAudioEngine so apps can handle raw audio input/output directly without using legacy C AudioUnit APIs. It covers how to use these new nodes for real-time audio rendering and urges migrating from the now-deprecated C APIs to AVAudioEngine.
