使用java和socket进行vocie聊天，在局域网上连接时延迟

我正在使用socket和java编写语音聊天代码，两个客户端通话成功，但延迟1-2秒。我不知道为什么。导致网络速度或我的代码

线程播放器

public class player extends Thread{
public DataInputStream din = null;
public SourceDataLine audio_out;
byte byte_buff[] = new byte[256];
    @Override
    public void run(){
        try {
            while(din.read(byte_buff)!= -1){
                audio_out.write(byte_buff, 0, byte_buff.length);
            }
            audio_out.drain();
            audio_out.close();
        } catch (IOException ex) {
            Logger.getLogger(player.class.getName()).log(Level.SEVERE, null, ex);
        } finally {
            try {
                din.close();
            } catch (IOException ex) {
                Logger.getLogger(player.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    }

线程记录器

public class recorder extends Thread{
    public DataOutputStream dout = null;
    public TargetDataLine audio_in = null;
    byte byte_buff[] = new byte[256];
    @Override
    public void run(){
        try {
            while(true){
                int data = audio_in.read(byte_buff, 0, byte_buff.length);
                //audio_out.write(byte_buff, 0, byte_buff.length);
                System.out.println("sending");
                dout.write(byte_buff);
                dout.flush();
            }
        } catch (IOException ex) {
            Logger.getLogger(recorder.class.getName()).log(Level.SEVERE, null, ex);
        } finally {
            try {
                dout.close();
            } catch (IOException ex) {
                Logger.getLogger(recorder.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    }

螺纹转移

public class transfer extends Thread{
    DataInputStream din;
    DataOutputStream dout;
    byte byte_buff[] = new byte[256];
    @Override
    public void run(){
        try {
            while(din.read(byte_buff)!= -1){
                dout.write(byte_buff, 0, byte_buff.length);
                System.out.println("tranferring");
            }
        } catch (IOException ex) {
            System.out.println("voice disconnect");
        } finally {
            try {
                din.close();
            } catch (IOException ex) {
                Logger.getLogger(transfer.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    }

运行没有问题，但延迟约1-2秒，两个客户端在LAN上连接。

请帮助我，还有java的实时协议RTP，我相信它就是为了解决这类问题而设计的。

对于初学者来说，TCP可能有很大的抖动，这是它从不用于语音聊天的主要原因之一。你应该改用UDP。谢谢，我照你说的做了，成功非常感谢：）
