How can I play sound in Java?

Question

I want to be able to play sound files in my program. Where should I look?

Answer 1

This thread is rather old but I have determined an option that could prove useful.

Instead of using the Java AudioStream library you could use an external program like Windows Media Player or VLC and run it with a console command through Java.

String command = "\"C:/Program Files (x86)/Windows Media Player/wmplayer.exe\" \"C:/song.mp3\"";
try {
    Process p = Runtime.getRuntime().exec(command);
catch (IOException e) {
    e.printStackTrace();
}

This will also create a separate process that can be controlled it the program.

p.destroy();

Of course this will take longer to execute than using an internal library but there may be programs that can start up faster and possibly without a GUI given certain console commands.

If time is not of the essence then this is useful.

It works for me. Simple variant

public void makeSound(){
    File lol = new File("somesound.wav");
    

    try{
        Clip clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(lol));
        clip.start();
    } catch (Exception e){
        e.printStackTrace();
    }
}

I created a game framework sometime ago to work on Android and Desktop, the desktop part that handle sound maybe can be used as inspiration to what you need.

https://github.com/hamilton-lima/jaga/blob/master/jaga%20desktop/src-desktop/com/athanazio/jaga/desktop/sound/Sound.java

Here is the code for reference.

package com.athanazio.jaga.desktop.sound;

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;

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;
import javax.sound.sampled.UnsupportedAudioFileException;

public class Sound {

    AudioInputStream in;

    AudioFormat decodedFormat;

    AudioInputStream din;

    AudioFormat baseFormat;

    SourceDataLine line;

    private boolean loop;

    private BufferedInputStream stream;

    // private ByteArrayInputStream stream;

    /**
     * recreate the stream
     * 
     */
    public void reset() {
        try {
            stream.reset();
            in = AudioSystem.getAudioInputStream(stream);
            din = AudioSystem.getAudioInputStream(decodedFormat, in);
            line = getLine(decodedFormat);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void close() {
        try {
            line.close();
            din.close();
            in.close();
        } catch (IOException e) {
        }
    }

    Sound(String filename, boolean loop) {
        this(filename);
        this.loop = loop;
    }

    Sound(String filename) {
        this.loop = false;
        try {
            InputStream raw = Object.class.getResourceAsStream(filename);
            stream = new BufferedInputStream(raw);

            // ByteArrayOutputStream out = new ByteArrayOutputStream();
            // byte[] buffer = new byte[1024];
            // int read = raw.read(buffer);
            // while( read > 0 ) {
            // out.write(buffer, 0, read);
            // read = raw.read(buffer);
            // }
            // stream = new ByteArrayInputStream(out.toByteArray());

            in = AudioSystem.getAudioInputStream(stream);
            din = null;

            if (in != null) {
                baseFormat = in.getFormat();

                decodedFormat = new AudioFormat(
                        AudioFormat.Encoding.PCM_SIGNED, baseFormat
                                .getSampleRate(), 16, baseFormat.getChannels(),
                        baseFormat.getChannels() * 2, baseFormat
                                .getSampleRate(), false);

                din = AudioSystem.getAudioInputStream(decodedFormat, in);
                line = getLine(decodedFormat);
            }
        } catch (UnsupportedAudioFileException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (LineUnavailableException e) {
            e.printStackTrace();
        }
    }

    private SourceDataLine getLine(AudioFormat audioFormat)
            throws LineUnavailableException {
        SourceDataLine res = null;
        DataLine.Info info = new DataLine.Info(SourceDataLine.class,
                audioFormat);
        res = (SourceDataLine) AudioSystem.getLine(info);
        res.open(audioFormat);
        return res;
    }

    public void play() {

        try {
            boolean firstTime = true;
            while (firstTime || loop) {

                firstTime = false;
                byte[] data = new byte[4096];

                if (line != null) {

                    line.start();
                    int nBytesRead = 0;

                    while (nBytesRead != -1) {
                        nBytesRead = din.read(data, 0, data.length);
                        if (nBytesRead != -1)
                            line.write(data, 0, nBytesRead);
                    }

                    line.drain();
                    line.stop();
                    line.close();

                    reset();
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

A bad example:

import  sun.audio.*;    //import the sun.audio package
import  java.io.*;

//** add this into your application code as appropriate
// Open an input stream  to the audio file.
InputStream in = new FileInputStream(Filename);

// Create an AudioStream object from the input stream.
AudioStream as = new AudioStream(in);         

// Use the static class member "player" from class AudioPlayer to play
// clip.
AudioPlayer.player.start(as);            

// Similarly, to stop the audio.
AudioPlayer.player.stop(as);
