actionscript 3 -通过RTMFP发送ByteArray中的声音

Question

我正在构建一个语音聊天操作语音数据。我从麦克风得到SAMPLE_DATA (ByteArray)并通过NetStream send()方法发送它。然后我必须将它转换回声音。我该怎么做呢?

这是类建立连接，捕获和发送语音数据(我知道这是丑陋的，但它是临时版本)。

package app.net {
public class CirrusConnection extends EventDispatcher {
    private const SERVER_ADDRESS:String = "rtmfp://p2p.rtmfp.net/";
    private const DEVELOPER_KEY:String = "bla-bla-bla";
    // Net objects ~~~~~~~~~~
    private var nc:NetConnection;
    private var sendStream:NetStream;
    private var recvStream:NetStream;
    private var myPeerID:String;
    private var farPeerID:String;
    // User output handler
    private var chatTextArea:TextArea;
    //---
    private var mic:Microphone;
    //---
    public function CirrusConnection() { }
    public function initConnection():void {
        nc = new NetConnection();
        nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
        nc.connect(SERVER_ADDRESS + DEVELOPER_KEY);
        mic = Microphone.getMicrophone();
        mic.rate = 8;
        mic.setUseEchoSuppression(true);
        mic.gain = 50;
    }
    private function netStatusHandler(event:NetStatusEvent):void {
        trace("CirrusConnection: " + event.info.code);
        switch(event.info.code) {
            case "NetConnection.Connect.Success":
                myPeerID = nc.nearID;
                openSendStream();
                dispatchEvent(new Event(NetEvent.CIRRUS_SENT_KEY));
                break;
            case "NetStream.Play.Start":
                dispatchEvent(new Event(NetEvent.CLIENT_IS_CALLING ));
                break;
        }
    }
    public function getNetConnection():NetConnection {
        return nc;
    }
    public function getMyPeerID():String {
        return myPeerID;
    }
    public function isConnected():Boolean {
        return Boolean(myPeerID);
    }
    public function setChatTextArea(chatTextArea:TextArea):void {
        this.chatTextArea = chatTextArea;
    }
    private function openSendStream():void {
        var sendStreamClient:Object = new Object();
        sendStreamClient.onPeerConnect = function(callerns:NetStream):Boolean {
            if (!Boolean(farPeerID)) {
                connectToPeer(callerns.farID);
            }
            return true;
        }
        sendStream = new NetStream(this.nc, NetStream.DIRECT_CONNECTIONS);
        sendStream.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
        sendStream.client = sendStreamClient;
        sendStream.publish("media");
    }
    public function connectToPeer(id:String):void {
        farPeerID = id;
        recvStream = new NetStream(nc,farPeerID);
        recvStream.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler);
        recvStream.client = this;
        recvStream.play("media");
    }
    public function read(data:ByteArray):void {
        var snd:Sound = new Sound();
        data.position = 0;
        snd.loadPCMFromByteArray(data, data.length >> 3);
        snd.play();
    }
    public function beginStreamMicrophoneData():void {
        mic.addEventListener("sampleData", streamData);
    }
    public function streamData(event:SampleDataEvent):void {
        sendStream.send("read", event.data as ByteArray );
    }
}
}

当麦克风数据被捕获时，

streamData函数正在调用。它正在向另一个对等体发送ByteArray。第二个对等体在读取函数中获取它。会有东西解码它。现在它工作了，但我的扬声器里有很糟糕的常规声音。如果您能及时回复，我将不胜感激，提前表示感谢。

你的方法似乎是合理的，尽管我总是看到一个媒体服务器在流媒体源和接收器之间。您可以尝试设置Red5(或类似)，流式传输音频作为"现场"源，然后从另一边播放它。

虽然在传输中可能是 PCM(尽管有几种可用的压缩)，但您可能会听到噪音，因为您错过了翻译的一个步骤。
