Declaration
var hasHardwareVoiceCallProcessing: Bool { get }Discussion
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.
