AudioClip volume problems

Question

I watched a great tutorial of Mattew on how to implement audio sounds in Java games.

The problem is that even after I decreased the volume of the wav file when I run the game the volume of the wav sound file is still very high in Java, I mean you can't even play the game because of the background music that is too loud.

Why the volume of the wav file is not maintaining in Java?

It is probably better to use the Java Sound based `Clip` than the applet based `AudioClip`. The `Clip` interface supports controls, one of which should be a volume. Further, if you found a video tutorial recommending `AudioClip` it is either very old, or the author is not worth listening to, or both. — Andrew Thompson, Jan 01 '14 at 20:48

It is probably better to use the Java Sound based Clip than the applet based AudioClip. The Clip interface supports controls, one of which should be a MASTER_GAIN.

E.G.

import java.awt.*;
import java.net.URL;
import javax.swing.*;
import javax.swing.event.*;
import javax.sound.sampled.*;

class ClipVolume {

    public static void main(String[] args) throws Exception {
        URL url = new URL(
                "http://pscode.org/media/leftright.wav");
        final Clip clip = AudioSystem.getClip();
        // getAudioInputStream() also accepts a File or InputStream
        AudioInputStream ais = AudioSystem.getAudioInputStream(url);
        clip.open(ais);
        clip.loop(Clip.LOOP_CONTINUOUSLY);
        Runnable r = new Runnable() {

            @Override
            public void run() {
                final FloatControl control = (FloatControl) 
                        clip.getControl(FloatControl.Type.MASTER_GAIN);

                final JSlider volume = new JSlider(
                        JSlider.HORIZONTAL,
                        (int) control.getMinimum(),
                        (int) control.getMaximum(),
                        (int) control.getValue());
                volume.addChangeListener(new ChangeListener() {

                    public void stateChanged(ChangeEvent ce) {
                        control.setValue(volume.getValue());
                    }
                });

                JOptionPane.showMessageDialog(null, volume);
            }
        };
        // Swing GUIs should be created and updated on the EDT
        // http://docs.oracle.com/javase/tutorial/uiswing/concurrency
        SwingUtilities.invokeLater(r);
    }
}

Thank you very much, this is what i was looking for, i will try this solution and i'll let you know.Thanks again. — stefanbanu, Jan 02 '14 at 18:05
