Question

还有另一个应用程序在此套接字上写入原始wav文件。客户端启动并开始收听当前正在播放的歌曲。

Socket clientSocket = new Socket("localhost", 9595);
AudioInputStream stream = AudioSystem.getAudioInputStream(clientSocket.getInputStream());

我得到 javax.sound.sampled.UnsupportedAudioFileException：无法从输入流中获取音频输入流

关于AudioSystem.getAudioInputStream的文档：“从提供的输入流中获取音频输入流。该流必须指向有效的音频文件数据。”

如何从TCP流播放声音？考虑到客户端无法从音乐的开头开始收听。

Answer 1

打开AudioInputStream不会播放来自此流的声音。您需要打开一个Clip来播放来自流的声音。我根本不是专家，但你应该通过阅读the Java tutorial来学习如何做到这一点。

import javax.sound.sampled.*;
import java.io.IOException;
import java.io.InputStream;
import java.net.Socket;

public class Client {

    public static int PORT = 3000;

    SourceDataLine _speaker;
    InputStream _streamIn;
    Socket _server;
    String _serverName = "127.0.0.1";
    boolean _running = true;

    public Client(String serverName) throws IOException,LineUnavailableException {
        this._serverName = serverName;
        init();
    }

    private void init() throws LineUnavailableException{
        //  specifying the audio format
        AudioFormat _format = new AudioFormat(8000.F,// Sample Rate
                16,     // Size of SampleBits
                1,      // Number of Channels
                true,   // Is Signed?
                false   // Is Big Endian?
        );

        //  creating the DataLine Info for the speaker format
        DataLine.Info speakerInfo = new DataLine.Info(SourceDataLine.class, _format);

        //  getting the mixer for the speaker
        _speaker = (SourceDataLine) AudioSystem.getLine(speakerInfo);
        _speaker.open(_format);
    }

    public void Start() {
        try {
            System.out.println("Connecting to server @" + _serverName + ":" + PORT);

            //  creating the socket and connect to the server
            _server = new Socket(_serverName, PORT);
            System.out.println("Connected to: " + _server.getRemoteSocketAddress());

            //  gettting the server stream
            _streamIn = _server.getInputStream();

            _speaker.start();

            byte[] data = new byte[8000];
            System.out.println("Waiting for data...");
            while (_running) {

                //  checking if the data is available to speak
                if (_streamIn.available() <= 0)
                    continue;   //  data not available so continue back to start of loop

                //  count of the data bytes read
                int readCount= _streamIn.read(data, 0, data.length);

                if(readCount > 0){
                    _speaker.write(data, 0, readCount);
                }
            }

            //honestly.... the control never reaches here.
            _speaker.drain();
            _speaker.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
