左/右声道平衡立体声不适用于Apple Airpods（蓝牙）

Question

我正在使用AudioKit创建一个实验性的iOS音频应用程序。 目前，我正在尝试一次仅在一个扬声器（左/右立体声）上录制和播放音频，但是在设置左/右立体声通道后它在两个扬声器上播放（来自设置的滑块平衡控制＆gt;一般＆gt;辅助功能＆gt;滑块左/右声道）。

实际上，我只需要在左侧或右侧Apple Airpods耳机上录制和播放音频。在辅助功能上更改左/右声道设置时。

   AKSettings.bufferLength = .medium
   do {
       try AKSettings.setSession(category: .playAndRecord, with: .allowBluetoothA2DP)
   } catch {
       AKLog("Could not set session category.")
   }

    AKSettings.defaultToSpeaker = true
    AKSettings.useBluetooth = true
    // Patching
    inputPlot.node = mic
    micMixer = AKMixer(mic)
    micBooster = AKBooster(micMixer)

   // Will set the level of microphone monitoring
    micBooster.gain = 1
   recorder = try? AKNodeRecorder(node: micMixer)

    if let file = recorder.audioFile {

        player = try? AKAudioPlayer(file: file)
   }

    player.looping = true
    player.completionHandler = playingEnded

    moogLadder = AKMoogLadder(player)

    mainMixer = AKMixer(moogLadder, micBooster)

    AudioKit.output = mainMixer

    AudioKit.start()
