Is your question about getting the intensity (it's a number, in dB)? Or about making a display? These are two different parts to your problem and they deserve separate questions. – Ben Voigt Oct 23 '18 at 20:37

@BenVoigt I'm gonna use a progress bar with range 0..100 to display the intensity. – applexis Oct 24 '18 at 07:03

Seems orignal post is wrong direction and missunderstanding. See this API:AudioDeviceController.VolumePercent

It sounds like you are talking about controlling and displaying the *gain*, but my understanding of the question is that it concerns the signal level not the gain. – Ben Voigt Oct 24 '18 at 13:39

@applexis Just provided an API which might help. But it is still not so clear about your whole scenario. Are you using MediaCapture to capturing photos, audio, and videos from a capture device? If so then the API I mentioned might work. Otherwise it is still wrong post. – Barry Wang Oct 25 '18 at 01:25

@BenVoigt Yep. It is misunderstanding. Let me clarify OP's scenario again. If it is still not on the right direction for him, I will delete the answer. Thank you for point it out. – Barry Wang Oct 25 '18 at 01:26
