Instance Property


Information about the host context in which the audio unit is connected, for display in the audio unit’s view.


var contextName: String? { get set }


For example—a host could set “track 3” as the context, so that the audio unit’s view could then display “My audio unit on track 3”.

This version 3 property is bridged to the version 2 kAudioUnitProperty_ContextName API.
