I've tried to search similiar question to this, but couldn't find. I don't know how i can stop my sound when button is released, and also, i don't know how to loop sound only one by one, when i hold button it plays again while previous loop is still playing, and the sound is becoming a loop from ∞ sounds.
Here's the code:
import java.applet.Applet;
import java.applet.AudioClip;
import java.awt.Component;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;

import java.net.MalformedURLException;

public class test {
String b[]={"Q","W","E","R","T","Y","U","I","O","P","A","S","D","F","G","H","J","K","L","Z","X","C","V","B","N","M"};
Action[] actions = new AbstractAction[26];
public test() throws Exception {
JFrame frame = new JFrame();
JButton[] buttons = new JButton[26];
for(int i = 0; i < buttons.length; i++) {
buttons[i] = new JButton(b[i]);
buttons[i].setSize(80, 80);
buttons[i].addKeyListener(new KeyAdapter(){
public void keyPressed(KeyEvent e){
System.out.println(e.getKeyChar());
playSound(new File("loopbase/loop1/"+e.getKeyChar()+".wav"));
}
public void keyReleased(KeyEvent e){
}
});
frame.add(buttons[i]);
}
JPanel contentPane = (JPanel)frame.getContentPane();
frame.setLayout(new GridLayout(3, 5, 5, 3));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable(){
public void run() {
try {
new test();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
public void playSound(File soundName)
{
try
{
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundName.getAbsoluteFile( ));
Clip clip = AudioSystem.getClip( );
clip.open(audioInputStream);
clip.start( );
}
catch(Exception ex)
{
System.out.println("Error with playing sound.");
ex.printStackTrace( );
}
}
}
Anyone can help me with this issue?
I don't know how i can stop my sound when button is released?
You can stop the the clip by using DataLine#stop() . Just keep the reference of last played clip and call below line to stop it.
clip.stop();
Note: You can store it somewhere in static
variable.
Sample code:
private static Clip clip;
...
public void keyReleased(KeyEvent e) {
if (clip != null) {
clip.stop();
}
}
...
public void playSound(File soundName) {
...
clip = AudioSystem.getClip();
...
}
When I hold the Button it plays again while previous loop is still playing.
This is because for every keyPress
you are creating a new File
object. That should be avoided.
To stop sound: I would add a boolean
parameter to playsound
method. And depending upon the parameter passed I would call clip.start()
or clip.stop()
(superclass DataLine has a stop method) . Call playsound(filename,false);
in keyReleased
.
public void playSound(File soundName , boolean start)
{
try
{
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundName.getAbsoluteFile( ));
Clip clip = AudioSystem.getClip( );
clip.open(audioInputStream);
if(start == true)
clip.start();
else
clip.stop();
}
catch(Exception ex)
{
System.out.println("Error with playing sound.");
ex.printStackTrace( );
}
}
