How to change AVCaptureSession audio volume?

I'm capturing video+audio with AVCaptureSession. Capture inputs are standard audio and video AVCaptureDevice. Capture output is AVCaptureMovieFileOutput. How one can change audio volume?

Solution

  • Audio volume could be changed with shared AVAudioSession like this:

    try! AVAudioSession.sharedInstance().setInputGain(0.5)
