我已经构建了一个混音器,并将所有序列保存在一个数组中然后再次播放,现在我想将混音保存为MP3,我已经找到了保存混音的方法,答案是将声音加载为byteArrays (sound.extract)我很熟悉,但我真的不知道如何将所有声音存储在一个ByteArray中以便将其保存为MP3,我只是举例说明,加载2个音频文件并存储它们单独的ByteArrays,并播放每个声音,任何人都知道如何只存储2个byteArrays吗？

var mySound:Sound = new Sound(); 
var sourceSnd:Sound = new Sound(); 
var urlReq:URLRequest = new URLRequest("Track1.mp3"); 
sourceSnd.load(urlReq); 
sourceSnd.addEventListener(Event.COMPLETE, loaded); 
function loaded(event:Event):void 
{ 
    mySound.addEventListener(SampleDataEvent.SAMPLE_DATA, processSound); 
    //mySound.play(); 
} 

var mySound2:Sound = new Sound(); 
var sourceSnd2:Sound = new Sound(); 
var urlReq2:URLRequest = new URLRequest("Track2.mp3"); 
sourceSnd2.load(urlReq2); 
sourceSnd2.addEventListener(Event.COMPLETE, loaded2); 
function loaded2(event:Event):void 
{ 
    mySound2.addEventListener(SampleDataEvent.SAMPLE_DATA, processSound2); 
    mySound2.play(); 
    mySound.play(); 
} 



function processSound(event:SampleDataEvent):void 
{ 
        var bytes:ByteArray = new ByteArray(); 
        sourceSnd.extract(bytes, 8192); 
    event.data.writeBytes(bytes); 
} 

function processSound2(event:SampleDataEvent):void 
{ 
        var bytes:ByteArray = new ByteArray(); 
        sourceSnd2.extract(bytes, 8192); 
    event.data.writeBytes(bytes); 
}
