Я использую AudioKit 4.8 вот так 

class AudioKitWrapper {

    /// The main output mixer (after the amplitude tracker)
    private let masterMixer:  AKMixer

    /// The audio input
    private var microphone:   EZMicrophone?

    /// Construction
    init() {
        // global settings
        AKAudioFile.cleanTempDirectory()
        AKSettings.defaultToSpeaker = true
        AKSettings.enableRouteChangeHandling = true
        AKSettings.enableCategoryChangeHandling = true
        AKSettings.disableAVAudioSessionCategoryManagement = true
        AKSettings.audioInputEnabled = true
        AKSettings.playbackWhileMuted = false
        #if DEBUG
            AKSettings.enableLogging = AppConfig.AudioConfig.debugLogEnabled
        #endif
        // main mixer
        masterMixer = AKMixer()
    }

    /// Start up audiokit
    func startEngine(with audioInput: Bool) throws {
        // connect main nodes
        AudioKit.output = masterMixer
        // input
        microphone?.delegate = nil
        microphone = nil
        if audioInput {
            AKSettings.enableEchoCancellation = true
            let sizeOfFloat = UInt32(MemoryLayout<Float>.stride)
            microphone = EZMicrophone(microphoneDelegate: self,
                                      with: AudioStreamBasicDescription(mSampleRate: Float64(mirgaFactory.getSampleRate()),

Я получаю сообщения этого журнала без сбоев (сотни из них, я полагаю, на каждый аудиофрейм)

Я получаю сообщения этого журнала без сбоев (сотнииз них, я предполагаю, для каждого аудио кадра)

Есть идеи, откуда приходит это сообщение?
