我怎样才能用Java播放声音？

Question

我希望能够在我的程序中播放声音文件.我应该在哪里看？

Answer 1

我写了下面的代码,工作正常.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();
}

一个坏例子:

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);

我不想拥有这么多代码只是为了播放一个简单的该死的声音.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:您需要初始化JavaFX.一个快速的方法是在你的应用程序中调用一次JFXPanel()的构造函数:

static{
    JFXPanel fxPanel = new JFXPanel();
}

要在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();
   }
}

无论出于何种原因，当我调用this.getClass（）。getResourceAsStream（）时，wchargin的最高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);
    audioIn = AudioSystem.getAudioInputStream(f.toURI().toURL());  
    Clip clip = AudioSystem.getClip();
    clip.open(audioIn);
    clip.start();
}

我会用以下声音播放声音：

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

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