Cómo jugar archivos.wav con java

audio

Question

Estoy tratando de reproducir un archivo * .wav con Java. Quiero que haga lo siguiente:
Cuando se presiona un botón, reproduce un pitido corto.

Lo busqué en Google, pero la mayoría del código no funcionaba. ¿Alguien puede darme un fragmento de código simple para reproducir un archivo .wav?

Answer 1

Aquí está la forma más elegante que podría encontrar sin usar el sol. *:

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
}

Answer 2

El fragmento here funciona bien, probado con sonido de Windows:

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

Answer 3

Finalmente logré hacer lo siguiente y funciona bien

import java.io.File;
import java.io.IOException;

import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;

public class MakeSound {

    private final int BUFFER_SIZE = 128000;
    private File soundFile;
    private AudioInputStream audioStream;
    private AudioFormat audioFormat;
    private SourceDataLine sourceLine;

    /**
     * @param filename the name of the file that is going to be played
     */
    public void playSound(String filename){

        String strFilename = filename;

        try {
            soundFile = new File(strFilename);
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(1);
        }

        try {
            audioStream = AudioSystem.getAudioInputStream(soundFile);
        } catch (Exception e){
            e.printStackTrace();
            System.exit(1);
        }

        audioFormat = audioStream.getFormat();

        DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat);
        try {
            sourceLine = (SourceDataLine) AudioSystem.getLine(info);
            sourceLine.open(audioFormat);
        } catch (LineUnavailableException e) {
            e.printStackTrace();
            System.exit(1);
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(1);
        }

        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) {
                @SuppressWarnings("unused")
                int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
            }
        }

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

Answer 4

Forma más corta (sin tener que instalar bibliotecas aleatorias)?

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);
    }
}

El único problema es que no hay una buena manera de hacer que este método bloquee para cerrar y eliminar los datos después de que * .wav finalice. clip.drain() dice que está bloqueando, pero no lo es. El clip no se está ejecutando DERECHO DESPUÉS de start() . La única forma de trabajo pero fea que encontré es:

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

Otra forma de hacerlo con 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();
        }
    }
}

Answer 6

Puede usar un detector de eventos para cerrar el clip después de que se reproduzca

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);
    }
}

También puede usar AudioStream de esta manera:

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();
            }
        }
    }

}

Answer 8

Una clase que reproducirá un archivo WAV, bloqueando hasta que el sonido haya terminado de reproducirse:

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();
    }
}

Una solución sin reflexión java DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat)

La reflexión de Java disminuye el rendimiento. ejecutar: 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();
    }

}
