AS3文档中有相关的代码，你可以自己理解一下。

package {
import flash.display.Sprite;
import flash.net.URLRequest;
import flash.media.Sound;
import flash.text.TextField;
import flash.text.TextFieldAutoSize;
import flash.events.ProgressEvent;
import flash.events.IOErrorEvent;

public class Sound_loadExample extends Sprite {
private var snd:Sound = new Sound();
private var statusTextField:TextField = new TextField();

public function Sound_loadExample(){

statusTextField.autoSize = TextFieldAutoSize.LEFT;
var req:URLRequest = new URLRequest("http://av.adobe.com/podcast/csbu_dev_podcast_epi_2.mp3");

try {
snd.load(req);

snd.play();
}
catch (err:Error) {
trace(err.message);
}

snd.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
snd.addEventListener(ProgressEvent.PROGRESS, progressHandler);

this.addChild(statusTextField);
}

private function progressHandler(event:ProgressEvent):void {
var loadTime:Number = event.bytesLoaded / event.bytesTotal;
var LoadPercent:uint = Math.round(100 * loadTime);

statusTextField.text = "Sound file's size in bytes: " + event.bytesTotal + "\n"
+ "Bytes being loaded: " + event.bytesLoaded + "\n"
+ "Percentage of sound file that is loaded " + LoadPercent + "%.\n";
}

private function errorHandler(errorEvent:IOErrorEvent):void {
statusTextField.text = "The sound could not be loaded: " + errorEvent.text;
}
}
}
