How to play a sound (alert) in a java application? [duplicate]

Question

I am working with a SMS handling, java based software and want to play a beep / alert sound whenever we receive a message. I tried looking at the java.sound libraries and could not find anything. I do not know if going the applet way of playing a sound will be okay in a java application! Are there any predefined sounds in any java libraries which we can call in an application? Any pointers will be appreciated!

Answer 1

If you just want a beep or quick alert try

Toolkit.getDefaultToolkit().beep(); 

Answer 2

You can generate your own sound if you looking for something less boring than a beep() without an external sound file.

import javax.sound.sampled.*;  public class SoundUtils {    public static float SAMPLE_RATE = 8000f;    public static void tone(int hz, int msecs)       throws LineUnavailableException    {      tone(hz, msecs, 1.0);   }    public static void tone(int hz, int msecs, double vol)       throws LineUnavailableException    {     byte[] buf = new byte[1];     AudioFormat af =          new AudioFormat(             SAMPLE_RATE, // sampleRate             8,           // sampleSizeInBits             1,           // channels             true,        // signed             false);      // bigEndian     SourceDataLine sdl = AudioSystem.getSourceDataLine(af);     sdl.open(af);     sdl.start();     for (int i=0; i < msecs*8; i++) {       double angle = i / (SAMPLE_RATE / hz) * 2.0 * Math.PI;       buf[0] = (byte)(Math.sin(angle) * 127.0 * vol);       sdl.write(buf,0,1);     }     sdl.drain();     sdl.stop();     sdl.close();   }    public static void main(String[] args) throws Exception {     SoundUtils.tone(1000,100);     Thread.sleep(1000);     SoundUtils.tone(100,1000);     Thread.sleep(1000);     SoundUtils.tone(5000,100);     Thread.sleep(1000);     SoundUtils.tone(400,500);     Thread.sleep(1000);     SoundUtils.tone(400,500, 0.2);    } }
