Instance Property


A Boolean value that indicates whether the associated hardware port has built-in processing for two-way voice communication.


var hasHardwareVoiceCallProcessing: Bool { get }


Applications that use their own proprietary voice-processing algorithms should use this property to decide when to disable processing. If your app uses Apple’s Voice Processing I/O unit (subtype kAudioUnitSubType_VoiceProcessingIO), the system automatically manages this for you.
