Communicates to an audio unit that it is rendering offline.
- iOS 10.0+
- macOS 10.12+
- tvOS 10.0+
A host should use this property when using an audio unit in a context where there are no realtime deadlines. An audio unit may respond by using a more expensive signal processing algorithm, or allowing itself to block at render time if data being generated on secondary work threads is not ready in time.
This version 3 property is bridged to the version 2 kAudioUnitProperty_OfflineRender API.
