Instance Property

isRenderingOffline

Communicates to an audio unit that it is rendering offline.

Declaration

var isRenderingOffline: Bool { get set }

Discussion

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.
