 Once you have captured a video to a file, you may want to load the file and play it back within your app's UI. You can do this using the **[MediaPlayerElement](/uwp/api/Windows.UI.Xaml.Controls.MediaPlayerElement)** XAML control and an associated **[MediaPlayer](/uwp/api/windows.media.playback.mediaplayer)**. For information on playing media in a XAML page, see [Play audio and video with MediaPlayer](/windows/uwp/audio-video-camera/play-audio-and-video-with-mediaplayer).

 You can also create a **[MediaClip](/uwp/api/windows.media.editing.mediaclip)** object from a video file by calling **[CreateFromFileAsync](/uwp/api/windows.media.editing.mediaclip.createfromfileasync)**.  A **[MediaComposition](/uwp/api/windows.media.editing.mediacomposition)** provides basic video editing functionality like arranging the sequence of **MediaClip** objects, trimming video length, creating layers, adding background music, and applying video effects. For more information on working with media compositions, see [Media compositions and editing](/windows/uwp/audio-video-camera/media-compositions-and-editing).
 
 
 ## Capture audio 
 
 You can quickly add audio capture to your app by using the same technique shown above for capturing video. Call [**PrepareLowLagRecordToStorageFileAsync**](/uwp/api/windows.media.capture.mediacapture.preparelowlagrecordtostoragefileasync) to initialize the capture session, passing in the file and a [**MediaEncodingProfile**](/uwp/api/Windows.Media.MediaProperties.MediaEncodingProfile) which is generated in this example by the [**CreateMp3**](/uwp/api/windows.media.mediaproperties.mediaencodingprofile.createmp3) static method. To begin recording, call [**StartAsync**](/uwp/api/windows.media.capture.lowlagmediarecording.startasync).

 Learn how to detect and respond to audio level changes by the system. Starting with Windows 10, version 1803, your app can detect when the system lowers or mutes the audio level of your app's audio capture and audio render streams. For example, the system may mute your app's streams when it goes into the background.

 The [**AudioStateMonitor**](/uwp/api/windows.media.audio.audiostatemonitor) class allows you to register to receive an event when the system modifies the volume of an audio capture or render stream. Get an instance of **AudioStateMonitor** for monitoring audio capture streams by calling [**CreateForCaptureMonitoring**](/uwp/api/windows.media.audio.audiostatemonitor.createforcapturemonitoring#Windows_Media_Audio_AudioStateMonitor_CreateForCaptureMonitoring). Get an instance for monitoring audio render streams by calling [**CreateForRenderMonitoring**](/uwp/api/windows.media.audio.audiostatemonitor.createforrendermonitoring). Register a handler for the [**SoundLevelChanged**](/uwp/api/windows.media.audio.audiostatemonitor.soundlevelchanged) event of each monitor to be notified when the audio for the corresponding stream category is changed by the system.
