I am trying determine the length of the kSystemSoundID_Vibrate vibration. I am trying to determine if I can mimic a specific pattern used by an external piece of hardware. I'm trying to understand how this pattern vibrates. I've seen difference ideas when I google it and none seem definitive. My own research, done by using AudioServicesPlaySystemSoundWithCompletion and recording the time before the call and after the call seem to indicate it is about 500ms. But if I string that call together multiple times there are gaps of silence.
So my conclusion is that the discussion I saw (probably on Stack overflow) that said it was 400ms of vibration and 100ms of silence was correct. Can anyone verify that for me?
