This is the first audio sample. It demonstrates the basic workflow of loading an external audio. You can also see the differences in pausing, replaying and seeking the audio element.

It seems that Flash has some bugs when trying to play at a specific position. You may experience that the progress bar will drop to zero when you click on the second half of the bar. However, it works perfectly in my Flash IDE and I don’t have any idea how to solve it.

Sound [AS3] vs MediaElement [C#]

Here is a simple demonstration in manipulating an external audio.

// AS3
var _sound:Sound;
var _soundChannel:SoundChannel;
var _position:Number;

var request : URLRequest = new URLRequest(URL);
_sound = new Sound();
_sound.addEventListener(Event.COMPLETE, on_complete);
_sound.load(request);  

// finish loading, play the audio
private function on_complete(e : Event):void{
	_soundChannel = _sound.play();
}

// pause the audio
_position = _soundChannel.position;
_soundChannel.stop();

// replay the audio
_soundChannel = _sound.play_position;

In Silverlight, Video and Audio shared the same Class MediaElement. Don’t forget to add the object to the stage. Otherwise, you can never load the audio. Personally, I like the Audio Object in Silverlight since the API seems simpler to use.

// C#
MediaElement _mediaElement = new MediaElement();
_mediaElement.Source = new Uri(URL, UriKind.Absolute);
_mediaElement.MediaOpened += new RoutedEventHandler(_mediaElement_MediaOpened);
LayoutRoot.Children.Add(_mediaElement);

// finish loading, play the audio
void _mediaElement_MediaOpened(object sender, RoutedEventArgs e)
{
	_mediaElement.Play();
}

// pause the audio
_mediaElement.Pause();

// replay the audio
_mediaElement.Play();
