Overview
The Audio Unit framework provides interfaces for hosting either version 2 or version 3 audio units and implementing version 3 audio processing plug-ins known as Audio Unit extensions. Developers implementing version 3 audio units should subclass the AUAudioUnit class.
Version 3 Audio Unit extensions can be used on iOS, tvOS, and macOS by host apps and distributed via the App Store.
To learn more about App Extensions and version 3 Audio Unit extensions, see the App Extension Programming Guide and the WWDC 2015 presentation Audio Unit Extensions.
