混合和播放多个曲目Actionscript 3

Question

我正在AS3中创建一个混音器。我有几个声音样本，用户可以选择创建自己的轨道。调音台将“混音”最多4个音轨，并根据需要播放“混合”音轨。我无法让声音同步播放。我很想在闪光灯中处理声音并想知道我错过了什么......这是目前的“混音”功能：

function mixIt(e:MouseEvent) {

    if (isPlaying) {
    channel1.stop();
            }
    var mChannel1:SoundChannel = new SoundChannel;
    var mChannel2:SoundChannel = new SoundChannel;

    var tUrl1:URLRequest = new URLRequest(trackChoice1);
    var tUrl2:URLRequest = new URLRequest(trackChoice2);
    var s1:Sound = new Sound();
    var s2:Sound = new Sound();

    var s1Done:Boolean = false;
    var s2Done:Boolean = false;

            s1.addEventListener(Event.COMPLETE, onSoundLoaded1);
    s2.addEventListener(Event.COMPLETE, onSoundLoaded2);

            s1.load(tUrl1);
    s2.load(tUrl2);

    function onSoundLoaded1(e:Event) {
        s1Done = true;
        if (s2Done) {
        playMix()
        }
    }
    function onSoundLoaded2(e:Event) {
        s2Done = true;
        if (s1Done) {
            trace("s2 Done")
            playMix()
        }
    }
    function playMix(){
    mChannel1 = s1.play(0, 2);
    mChannel2 = s2.play(0, 2);
    //trace("MIXING TRACKS :" + tUrl1 + " + " + tUrl2);
     }
}

尝试使用Sound.extract()和SampleDataEvent

将声音混合为字节数组
