我想从android向java服务器发送音频。 和流从另一个Android客户端收到的音频 使用下面的代码。

for android client:



        package com.example.demo;

        import org.springframework.boot.SpringApplication;
        import org.springframework.boot.autoconfigure.SpringBootApplication;

        import javax.sound.sampled.*;
        import java.io.ByteArrayInputStream;
        import java.io.File;
        import java.io.FileInputStream;
        import java.io.OutputStream;
        import java.net.*;

        @SpringBootApplication
        public class DemoApplication {

            AudioInputStream audioInputStream;
            static AudioInputStream ais;
            static AudioFormat format;
            static boolean status = true;
            static int port = 50005;
            static int sampleRate = 44100;
            static ServerSocket serverSocket1;

            public static void main(String[] args) {
                receiveAudioFromAndroidClient();
                //streamToClientFromLocalFlie();
                SpringApplication.run(DemoApplication.class, args);
            }

            private static void receiveAudioFromAndroidClient() {
                try {
                    DatagramSocket serverSocket = new DatagramSocket(50005);
                    serverSocket1 = new ServerSocket(8072);


                    byte[] receiveData = new byte[4096];

                    format = new AudioFormat(sampleRate, 16, 1, true, false);

                    while (status == true) {
                        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                            receiveData.length);

                        serverSocket.receive(receivePacket);

                        ByteArrayInputStream baiss = new ByteArrayInputStream(
                            receivePacket.getData());

                        ais = new AudioInputStream(baiss, format, receivePacket.getLength());

                    // A thread solve the problem of chunky audio
                        new Thread(new Runnable() {
                            @Override
                            public void run() {
                                toSpeaker(receivePacket.getData());
                                streamToClient(receivePacket.getData());
                            }
                        }).start();
                    }
                } catch (Exception ex) {
                ex.printStackTrace();
                }
            }

            private static void streamToClient(byte[] data) {
                Thread test = new Thread(new Runnable() {
                    @Override
                    public void run() {
                        try {
                            if (serverSocket1.isBound()) {
                                Socket socket = serverSocket1.accept();


                                socket.getOutputStream().write(data);
                            }
                        } catch (Exception ex) {
                            ex.printStackTrace();
                        }
                    }
                });

                test.start();
            }

            private static void streamToClientFromLocalFlie() {
                try {
                    File soundFile = new File("E:\\Music\\Dariush\\Kisti.mp3");

                    try (ServerSocket serverSocker = new ServerSocket(8072);
                        FileInputStream in = new FileInputStream(soundFile)) {
                        if (serverSocker.isBound()) {
                            Socket client = serverSocker.accept();
                            OutputStream out = client.getOutputStream();

                            byte buffer[] = new byte[2048];
                            int count;
                            while ((count = in.read(buffer)) != -1)
                                out.write(buffer, 0, count);
                        }
                     } catch (Exception ex) {
                        ex.printStackTrace();
                    }
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }

            public static void toSpeaker(byte soundbytes[]) {
                 try {
                     DataLine.Info dataLineInfo = new DataLine.Info(SourceDataLine.class, format);
                     SourceDataLine sourceDataLine = (SourceDataLine) AudioSystem.getLine(dataLineInfo);

                     sourceDataLine.open(format);

                    //FloatControl volumeControl = (FloatControl) sourceDataLine.getControl(FloatControl.Type.MASTER_GAIN);
                    //volumeControl.setValue(6.0206f);

                     sourceDataLine.start();
                     sourceDataLine.open(format);

                     sourceDataLine.start();

                    //System.out.println("format? :" + sourceDataLine.getFormat());

                    sourceDataLine.write(soundbytes, 0, soundbytes.length);
                    System.out.println(soundbytes.toString());
                    sourceDataLine.drain();
                    sourceDataLine.close();
                } catch (Exception e) {
                    System.out.println("Not working in speakers...");
                    e.printStackTrace();
            }
        }
    }


和java服务器:

    $(document).ready(function() {
       resize_to_fit();
    });

        function resize_to_fit() {
      var fontsize = $('div#outer div').css('font-size');
      $('div#outer div').css('font-size', parseFloat(fontsize) - 1);

        if ($('div#outer div').height() >= $('div#outer').height()) {
            resize_to_fit();
        }
      }

我从Android客户端发送音频并在java服务器上接收它然后在服务器上播放声音,但是当我从服务器向套接字端口上的另一个Android客户端发送音频时,声音已损坏。

我的代码中可能出现什么问题?

请帮帮我

抱歉我的英语很差
