Check if SoundChannel is playing sound

Question

How to check reliably if a SoundChannel is still playing a sound?

For example,

[Embed(source=\"song.mp3\")]
var Song: Class;

var s: Song = new Song         


        

Answer 1

I've done a little research and I can't find a way to query any object to determine if a sound is playing. You'll have to write a wrapper class and manage it yourself it seems.

package
{
    import flash.events.Event;
    import flash.media.Sound;
    import flash.media.SoundChannel;

    public class SoundPlayer
    {
        [Embed(source="song.mp3")]
        private var Song:Class;

        private var s:Song;
        private var ch:SoundChannel;
        private var isSoundPlaying:Boolean;

        public function SoundPlayer()
        {
            s = new Song();
            play();
        }

        public function play():void
        {
            if(!isPlaying)
            {
                ch = s.play();
                ch.addEventListener(
                    Event.SOUND_COMPLETE,
                    handleSoundComplete);
                isSoundPlaying = true;
            }
        }

        public function stop():void
        {
            if(isPlaying)
            {
                ch.stop();
                isSoundPlaying = false;
            }
        }

        private function handleSoundComplete(ev:Event):void
        {
            isSoundPlaying = false;
        }
    }
}
