Stream AAC audio file stored locally using NetStream class

Like this :

## BEGIN

var streamURL:String = "instru-53453.mp3"; //file is sotred in the same directory of swf

function netStatusHandler(event:NetStatusEvent) {
    switch (event.info.code) {
        case "NetConnection.Connect.Success":
            trace('Connect Success');
            break;
        case "NetStream.Play.StreamNotFound":
            trace("Stream not found");
            break;
    }
}

function connectStream():void {
    var stream:NetStream = new NetStream(connection);
    stream.client = this;
    stream.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);

    stream.play(streamURL);

    //I also tried this
    //var request:URLRequest = new URLRequest(streamURL);
    //stream.play(request);
}

var connection:NetConnection = new NetConnection();
connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
connection.connect(null);
   
connectStream();

## END
