Comment jouer.fichiers wav avec java

Voici la forme la plus élégante que je pourrais trouver sans utiliser sun.*:

import java.io.*;
import javax.sound.sampled.*;

try {
    File yourFile;
    AudioInputStream stream;
    AudioFormat format;
    DataLine.Info info;
    Clip clip;

    stream = AudioSystem.getAudioInputStream(yourFile);
    format = stream.getFormat();
    info = new DataLine.Info(Clip.class, format);
    clip = (Clip) AudioSystem.getLine(info);
    clip.open(stream);
    clip.start();
}
catch (Exception e) {
    //whatevers
}

Forme la plus courte (sans avoir à installer des bibliothèques aléatoires) ?

public static void play(String filename)
{
    try
    {
        Clip clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(new File(filename)));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

Le seul problème est qu'il n'y a pas de bon moyen de bloquer cette méthode pour fermer et éliminer les données après *.finitions wav. clip.drain() dit que ça bloque mais ce n'est pas le cas. Le clip n'est pas en cours d'exécution JUSTE APRÈS start(). La seule façon de travailler mais LAIDE que j'ai trouvée est:

// ...
clip.start();
while (!clip.isRunning())
    Thread.sleep(10);
while (clip.isRunning())
    Thread.sleep(10);
clip.close();

Vous pouvez utiliser un écouteur d'événement pour fermer le clip après sa lecture

import java.io.File;
import javax.sound.sampled.*;

public void play(File file) 
{
    try
    {
        final Clip clip = (Clip)AudioSystem.getLine(new Line.Info(Clip.class));

        clip.addLineListener(new LineListener()
        {
            @Override
            public void update(LineEvent event)
            {
                if (event.getType() == LineEvent.Type.STOP)
                    clip.close();
            }
        });

        clip.open(AudioSystem.getAudioInputStream(file));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

L'extrait ici fonctionne bien, testé avec le son Windows:

public static void main(String[] args) {
        AePlayWave aw = new AePlayWave( "C:\\WINDOWS\\Media\\tada.wav" );
        aw.start();     
}

Une classe qui va lire un fichier WAV, blocage jusqu'à ce que le son a fini de jouer:

class Sound implements Playable {

    private final Path wavPath;
    private final CyclicBarrier barrier = new CyclicBarrier(2);

    Sound(final Path wavPath) {

        this.wavPath = wavPath;
    }

    @Override
    public void play() throws LineUnavailableException, IOException, UnsupportedAudioFileException {

        try (final AudioInputStream audioIn = AudioSystem.getAudioInputStream(wavPath.toFile());
             final Clip clip = AudioSystem.getClip()) {

            listenForEndOf(clip);
            clip.open(audioIn);
            clip.start();
            waitForSoundEnd();
        }
    }

    private void listenForEndOf(final Clip clip) {

        clip.addLineListener(event -> {
            if (event.getType() == LineEvent.Type.STOP) waitOnBarrier();
        });
    }

    private void waitOnBarrier() {

        try {

            barrier.await();
        } catch (final InterruptedException ignored) {
        } catch (final BrokenBarrierException e) {

            throw new RuntimeException(e);
        }
    }

    private void waitForSoundEnd() {

        waitOnBarrier();
    }
}

Une autre façon de le faire avec AudioInputStream:

import java.io.File;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.Line;
import javax.sound.sampled.LineEvent;
import javax.sound.sampled.LineListener;
import javax.swing.JDialog;
import javax.swing.JFileChooser;

public class CoreJavaSound extends Object implements LineListener {
    File soundFile;

    JDialog playingDialog;

    Clip clip;

    public static void main(String[] args) throws Exception {
        CoreJavaSound s = new CoreJavaSound();
    }

    public CoreJavaSound() throws Exception {
        JFileChooser chooser = new JFileChooser();
        chooser.showOpenDialog(null);
        soundFile = chooser.getSelectedFile();

        System.out.println("Playing " + soundFile.getName());

        Line.Info linfo = new Line.Info(Clip.class);
        Line line = AudioSystem.getLine(linfo);
        clip = (Clip) line;
        clip.addLineListener(this);
        AudioInputStream ais = AudioSystem.getAudioInputStream(soundFile);
        clip.open(ais);
        clip.start();
    }

    public void update(LineEvent le) {
        LineEvent.Type type = le.getType();
        if (type == LineEvent.Type.OPEN) {
            System.out.println("OPEN");
        } else if (type == LineEvent.Type.CLOSE) {
            System.out.println("CLOSE");
            System.exit(0);
        } else if (type == LineEvent.Type.START) {
            System.out.println("START");
            playingDialog.setVisible(true);
        } else if (type == LineEvent.Type.STOP) {
            System.out.println("STOP");
            playingDialog.setVisible(false);
            clip.close();
        }
    }
}

Une solution sans réflexion java DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat)

La réflexion Java diminue les performances. pour exécuter: java playsound absoluteFilePathTo/file.wav

import javax.sound.sampled.*;
import java.io.*;
public class playsound {

    public static void main (String args[]) throws Exception {
        playSound (args[0]);
    }

    public static void playSound () throws Exception {
        AudioInputStream 
        audioStream = AudioSystem.getAudioInputStream(new File (filename));

        int BUFFER_SIZE = 128000;
        AudioFormat audioFormat = null;
        SourceDataLine sourceLine = null;

        audioFormat = audioStream.getFormat();

        sourceLine = AudioSystem.getSourceDataLine(audioFormat);
        sourceLine.open(audioFormat);
        sourceLine.start();

        int nBytesRead = 0;
        byte[] abData = new byte[BUFFER_SIZE];
        while (nBytesRead != -1) {
            try {
                nBytesRead = 
                audioStream.read(abData, 0, abData.length);
            } catch (IOException e) {
                e.printStackTrace();
            }

            if (nBytesRead >= 0) {
                int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
            }
        }

        sourceLine.drain();
        sourceLine.close();
    }

}

Vous pouvez également utiliser AudioStream de cette façon:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

import sun.audio.AudioPlayer;
import sun.audio.AudioStream;

public class AudioWizz extends JPanel implements ActionListener {

    private static final long serialVersionUID = 1L; //you like your cereal and the program likes their "serial"

    static AudioWizz a;
    static JButton playBuddon;
    static JFrame frame;

    public static void main(String arguments[]){

        frame= new JFrame("AudioWizz");
        frame.setSize(300,300);
        frame.setVisible(true);
        a= new AudioWizz();
        playBuddon= new JButton("PUSH ME");
        playBuddon.setBounds(10,10,80,30);
        playBuddon.addActionListener(a);

        frame.add(playBuddon);
        frame.add(a);
    }

    public void actionPerformed(ActionEvent e){ //an eventListener
        if (e.getSource() == playBuddon) {
            try {
                InputStream in = new FileInputStream("*.wav");
                AudioStream sound = new AudioStream(in);
                AudioPlayer.player.start(sound);
            } catch(FileNotFoundException e1) {
                e1.printStackTrace();
            } catch (IOException e1) {
                e1.printStackTrace();
            }
        }
    }

}
