    Availability

    Available in iOS 4.0 and later.

  • The parameters for inputs to the mix

    Declaration

    Swift

    var inputParameters: [AVAudioMixInputParameters]

    Objective-C

    @property(nonatomic, copy) NSArray <AVAudioMixInputParameters *> *inputParameters

    Discussion

    The array contains instances of AVAudioMixInputParameters. Note that an instance of AVAudioMixInputParameters is not required for each audio track that contributes to the mix; audio for those without associated AVAudioMixInputParameters will be included in the mix, processed according to default behavior.

    Availability

    Available in iOS 4.0 and later.
