如何在 Java 中播放声音？

Question

我希望能够在我的程序中播放声音文件。我应该去哪里看？

Answer 1

我编写了以下运行良好的代码。但我认为它只适用于.wav 格式。

public static synchronized void playSound(final String url) {
  new Thread(new Runnable() {
  // The wrapper thread is unnecessary, unless it blocks on the
  // Clip finishing; see comments.
    public void run() {
      try {
        Clip clip = AudioSystem.getClip();
        AudioInputStream inputStream = AudioSystem.getAudioInputStream(
          Main.class.getResourceAsStream("/path/to/sounds/" + url));
        clip.open(inputStream);
        clip.start(); 
      } catch (Exception e) {
        System.err.println(e.getMessage());
      }
    }
  }).start();
}

Answer 2

一个不好的例子：

import  sun.audio.*;    //import the sun.audio package
import  java.io.*;

//** add this into your application code as appropriate
// Open an input stream  to the audio file.
InputStream in = new FileInputStream(Filename);

// Create an AudioStream object from the input stream.
AudioStream as = new AudioStream(in);         

// Use the static class member "player" from class AudioPlayer to play
// clip.
AudioPlayer.player.start(as);            

// Similarly, to stop the audio.
AudioPlayer.player.stop(as); 

Answer 3

我不想为了播放一个简单的该死的声音而编写这么多行代码。如果你有 JavaFX 包（已经包含在我的 jdk 8 中），这可以工作。

private static void playSound(String sound){
    // cl is the ClassLoader for the current class, ie. CurrentClass.class.getClassLoader();
    URL file = cl.getResource(sound);
    final Media media = new Media(file.toString());
    final MediaPlayer mediaPlayer = new MediaPlayer(media);
    mediaPlayer.play();
}

注意：您需要initialize JavaFX。一种快速的方法是在您的应用程序中调用 JFXPanel() 的构造函数：

static{
    JFXPanel fxPanel = new JFXPanel();
}

Answer 4

在java中播放声音，可以参考以下代码。

import java.io.*;
import java.net.URL;
import javax.sound.sampled.*;
import javax.swing.*;

// To play sound using Clip, the process need to be alive.
// Hence, we use a Swing application.
public class SoundClipTest extends JFrame {

   public SoundClipTest() {
      this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      this.setTitle("Test Sound Clip");
      this.setSize(300, 200);
      this.setVisible(true);

      try {
         // Open an audio input stream.
         URL url = this.getClass().getClassLoader().getResource("gameover.wav");
         AudioInputStream audioIn = AudioSystem.getAudioInputStream(url);
         // Get a sound clip resource.
         Clip clip = AudioSystem.getClip();
         // Open audio clip and load samples from the audio input stream.
         clip.open(audioIn);
         clip.start();
      } catch (UnsupportedAudioFileException e) {
         e.printStackTrace();
      } catch (IOException e) {
         e.printStackTrace();
      } catch (LineUnavailableException e) {
         e.printStackTrace();
      }
   }

   public static void main(String[] args) {
      new SoundClipTest();
   }
}

Answer 5

无论出于何种原因，当我调用 this.getClass().getResourceAsStream() 时，wchargin 的最佳答案是给我一个空指针错误。

对我有用的是：

void playSound(String soundFile) {
    File f = new File("./" + soundFile);
    AudioInputStream audioIn = AudioSystem.getAudioInputStream(f.toURI().toURL());  
    Clip clip = AudioSystem.getClip();
    clip.open(audioIn);
    clip.start();
}

我会用以下方式播放声音：

 playSound("sounds/effects/sheep1.wav");

sounds/effects/sheep1.wav 位于我在 Eclipse 中项目的基本目录中（因此不在 src 文件夹中）。

Answer 6

我前段时间创建了一个游戏框架，用于 Android 和桌面，处理声音的桌面部分也许可以作为你需要的灵感。

除了导入适用于小程序和应用程序的声音文件之外，还有另一种方法：将音频文件转换为 .java 文件，然后在您的代码中简单地使用它们。

我开发了一个工具，可以让这个过程变得更容易。它大大简化了 Java Sound API。

Answer 8

我很惊讶没有人建议使用 Applet。 UseApplet。您必须将哔声音频文件作为wav 文件提供，但它可以工作。我在 Ubuntu 上试过这个：

package javaapplication2;

import java.applet.Applet;
import java.applet.AudioClip;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;

public class JavaApplication2 {

    public static void main(String[] args) throws MalformedURLException {
        File file = new File("/path/to/your/sounds/beep3.wav");
        URL url = null;
        if (file.canRead()) {url = file.toURI().toURL();}
        System.out.println(url);
        AudioClip clip = Applet.newAudioClip(url);
        clip.play();
        System.out.println("should've played by now");
    }
}
//beep3.wav was available from: http://www.pacdv.com/sounds/interface_sound_effects/beep-3.wav

Answer 9

它对我有用。简单变体

public void makeSound(){
    File lol = new File("somesound.wav");
    

    try{
        Clip clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(lol));
        clip.start();
    } catch (Exception e){
        e.printStackTrace();
    }
}

Answer 10

这个帖子比较老了，但我已经确定了一个可能有用的选项。

您可以使用 Windows Media Player 或 VLC 等外部程序并通过 Java 使用控制台命令运行它，而不是使用 Java AudioStream 库。

String command = "\"C:/Program Files (x86)/Windows Media Player/wmplayer.exe\" \"C:/song.mp3\"";
try {
    Process p = Runtime.getRuntime().exec(command);
catch (IOException e) {
    e.printStackTrace();
}

这也将创建一个可以控制它的程序的单独进程。

p.destroy();

当然，与使用内部库相比，这将花费更长的时间来执行，但在某些控制台命令的情况下，可能有一些程序可以更快地启动并且可能没有 GUI。

如果时间不是最重要的，那么这很有用。

Answer 11

我在播放 mp3 文件格式时遇到了很多问题 所以使用一些online converter将其转换为.wav

然后在下面的代码中使用（它更容易而不是支持 mp3）

try
{
    Clip clip = AudioSystem.getClip();
    clip.open(AudioSystem.getAudioInputStream(GuiUtils.class.getResource("/sounds/success.wav")));
    clip.start();
}
catch (Exception e)
{
    LogUtils.logError(e);
}
