Playing Wav and Mp3 in a Universal Windows Application.

I’ve written a lot about playing audio in XAML apps. I’ve used SharpDX, Native DirectX and more recently Audiograph. All this was to avoid having to add a MediaElement to the XAML tree. With XNA we could use the SoundEffect to fire-and-forget audioclips and Windows 8 never had a simple alternative to that.

UWP has come a long way since Windows 8 and here’s how you can use the MediaPlayer API to play wave and mp3 files.

UWP MediaPlayer

The MediaPlayer is part of UWP since v10.0.10240.0 and can be used like this:

private void OnButtonWavClick(object sender, RoutedEventArgs e)
{
Play("ms-appx:///matrix.wav");
}

private void Play(string fileName)
{
var mediaPlayer = new MediaPlayer();
mediaPlayer.Source = MediaSource.CreateFromUri(new Uri($"{fileName}", UriKind.RelativeOrAbsolute));
mediaPlayer.Play();
}
