title: AVFoundation Error Domain
body: <p>I have a problem using The Amazing Audio Engine library I think.</p>
  
  <p>In fact, when I'm trying to play a back track and record with the microphone at the same time, at the end of the record, when I'm entering in this method:</p>
  
  <pre><code>func captureOutput(captureOutput: AVCaptureFileOutput!, didFinishRecordingToOutputFileAtURL outputFileURL: NSURL!, fromConnections connections: [AnyObject]!, error: NSError!)
  </code></pre>
  
  <p>I have this error:</p>
  
  <blockquote>
    <p>Error Domain=AVFoundationErrorDomain Code=-11818 "Enregistrement arrêté" UserInfo={NSUnderlyingError=0x15d5a4cd0 {Error Domain=NSOSStatusErrorDomain Code=-16414 "(null)"}, AVErrorRecordingSuccessfullyFinishedKey=true, NSLocalizedRecoverySuggestion=Arrêtez toute autre action effectuée avec l’appareil d’enregistrement puis réessayez., NSLocalizedDescription=Enregistrement arrêté}</p>
  </blockquote>
  
  <p>For the video record I use, AVCaptureSession and for the audio play and the audio record, I use The Amazing Audio Engine.</p>
  
  <p>Do you have any idea of the problem ?</p>
