Could not play a sound in swing

Question

I am trying to play a .wav file everytime I press a button.

I've put the resource in the workspace, together with my project. Is that wrong?

I get this error message:

javax.sound.sampled.AudioInputStream@341bdd4c /home/fred/workspace/Projekt/src/GUI/sound/gangnam.wav java.lang.IllegalArgumentException: Invalid format

Here is the code:

public static void main (String [] args) {
    JFrame customBoardFrame = new JFrame("Custom Size.");
    customBoardFrame.getContentPane().add(new customSize());    
    customBoardFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    customBoardFrame.setSize(450, 310);
    customBoardFrame.setVisible(true);
    customBoardFrame.setResizable(false);
}

---

public class customSize extends JPanel implements ActionListener {

    JButton playButton = new JButton(" >> PLAY <<");
    JButton stopButton = new JButton(" >> STOP <<");
    JButton pauseButton = new JButton(" >> PAUSE <<");

    public customSize(){

        setLayout(null);

        playButton.setBounds(12, 173, 116, 40);
        add(playButton);

        playButton.addActionListener(this);
        pauseButton.addActionListener(this);
        stopButton.addActionListener(this);

        stopButton.setBounds(140, 173, 117, 40);
        add(stopButton);

        pauseButton.setBounds(269, 173, 140, 40);
        add(pauseButton);

    }

    public void actionPerformed(ActionEvent e){

        if (e.getSource().equals(playButton)) {

            try {
                String soundName = "gangnam.wav";    
                AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(soundName).getAbsoluteFile());
                System.out.println(audioInputStream);
                System.out.println(new File (soundName).getAbsolutePath());
                Clip clip = AudioSystem.getClip();
                clip.open(audioInputStream);
                clip.start();
            } catch (Exception e1) {
                System.out.println("Error.");
            }

        }
        if (e.getSource().equals(stopButton)) {
            System.out.println("Stop music.");
        }
        if (e.getSource().equals(pauseButton)) {
            System.out.println("Pause music.");
        }

    }
}

Answer 1

My first step in trying to solve this would be to manually inspect the properties of the wav file itself. In Windows, you can right-click and select properties. Then, there is a second tab that has things like bit rate and fps.

Java can support 44100 fps, and 16-bit encoding. There are DAWs now, though, that produce wav files at 48000 or 96000 fps, or at 24-bit or 32-bit encoding. Java does not support these currently, AFAIK.

If you have such a file, you can easily modify it into an acceptable format (stereo, 16-bit, 44100fps) with the program Audacity, which is a free download. Just make sure you get it from their home site. The first time I downloaded it, it was Popuppalooza for several hours until I was able to get rid of all the crapware that came with. The home site download (see wikipedia for the link) should be fine.

Check your audio file format. All supported in Your system formats can check by javax.sound.sampled.AudioSystem.getAudioFileTypes()
