  • Hi Nurul,

    I think we need two steps to capture audio and calculate the noise level.

    The first step, using MediaCaptureclass to get the audio. A code sample from MSDN. http://code.msdn.microsoft.com/windowsapps/Media-Capture-Sample-adf87622.

    The second step is to use the common way to calculate the noise level. You can see the method from the following link. http://stackoverflow.com/questions/4152201/calculate-decibels.

    You don’t mention the platform you are using, fortunately the MediaCapture can be used for windows store app and windows phone store app.
