We want to play background sound in our Windows Phone app, we can play using this below objects.
1) MediaElement — need to include phone.controls dll
2) SoundEffect – need to include XNA framework dlls
To Play Sound in background first we have to please audio file in our project. in my case I placed those audio file in Sounds folder. Then in Solution Explore right click on add audio file and go to Properties . In Build Action, set value to Content. Copy to Output Direct value to Copy if newer.
FrameworkDispatcher.Update(); //We have Update FrameworkDispatcher to play sound using SoundEffect
To Load Audio file:-
private SoundEffect soundeffObj;
LoadSoundFile("sounds/filename.wav", out soundeffObj);
private void LoadSoundFile(String FilePath, out SoundEffect Sound)
{
Sound = null;
try
{
// Holds informations about a file stream.
StreamResourceInfo SoundFileInfo = App.GetResourceStream(new Uri(FilePath, UriKind.Relative));
// Create the SoundEffect from the Stream
Sound = SoundEffect.FromStream(SoundFileInfo.Stream);
}
catch (NullReferenceException)
{
// Display an error message
MessageBox.Show("unable to load sound file from this path :" + FilePath);
}
}
Now soundeffObj object hold the Audio file, to play this audio file we can use .Play() method. Like this
soundeffObj.Play()
We can also play using MediaElement, check this code
I added Media Element in XAML code itself in my demo app. We can also add in runtime. Here is my XMAL code
mediaEle.Source = new Uri("sounds/Sleep Away.mp3", UriKind.Relative);
mediaEle.Volume = 1f;
mediaEle.MediaEnded += new RoutedEventHandler(mediaEle_MediaEnded); // To handle finish event
mediaEle.Visibility = Visibility.Collapsed;
Media Element Media Ended event:
private void mediaEle_MediaEnded(object sender, RoutedEventArgs e)
{
//Do something here
}
I upload my code to Github https://github.com/rish7/WindowsPhonePlaySound/
We can also Zune pause and resume, using our code lines. This code also presented in it.
Enjoy while coding..!
