Disable Audio Recording

Updated on Sep 15, 2025

This article shows how to stop the audio recording when a video is captured.

1. Add the control to the logical tree of the view and subscribe to its Loaded event. Then, set its AutoStart property to False.

   Defining RadWebCam

   XAML

   	<telerik:RadWebCam x:Name="radWebCam" AutoStart="False" Loaded="RadWebcam_Loaded"/>

2. In the event handler, get the camera device and video format, and call the Initialize method of the control. To disable the audio, set the last parameter ("audioDevice") of the Initialize method to null. Then start the camera.

   Starting the camera manually

   C#

   	private void RadWebcam_Loaded(object sender, RoutedEventArgs e)
   	{	    
   		ReadOnlyCollection<MediaFoundationDeviceInfo> videoDevices = RadWebCam.GetVideoCaptureDevices();            
   		ReadOnlyCollection<MediaFoundationVideoFormatInfo> videoFormats = RadWebCam.GetVideoFormats(videoDevices[0]);
   		this.radWebCam.Initialize(videoDevices[0], videoFormats[0], null);
   		this.radWebCam.Start();
   	}
