How to play .wav files with java
Finally I managed to do the following and it works fine
import java.io.File;
import java.io.IOException;
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;
public class MakeSound {
private final int BUFFER_SIZE = 128000;
private File soundFile;
private AudioInputStream audioStream;
private AudioFormat audioFormat;
private SourceDataLine sourceLine;
/**
* @param filename the name of the file that is going to be played
*/
public void playSound(String filename){
String strFilename = filename;
try {
soundFile = new File(strFilename);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
try {
audioStream = AudioSystem.getAudioInputStream(soundFile);
} catch (Exception e){
e.printStackTrace();
System.exit(1);
}
audioFormat = audioStream.getFormat();
DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat);
try {
sourceLine = (SourceDataLine) AudioSystem.getLine(info);
sourceLine.open(audioFormat);
} catch (LineUnavailableException e) {
e.printStackTrace();
System.exit(1);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
sourceLine.start();
int nBytesRead = 0;
byte[] abData = new byte[BUFFER_SIZE];
while (nBytesRead != -1) {
try {
nBytesRead = audioStream.read(abData, 0, abData.length);
} catch (IOException e) {
e.printStackTrace();
}
if (nBytesRead >= 0) {
@SuppressWarnings("unused")
int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
}
}
sourceLine.drain();
sourceLine.close();
}
}
Here is the most elegant form I could come up without using sun.*:
import java.io.*;
import javax.sound.sampled.*;
try {
File yourFile;
AudioInputStream stream;
AudioFormat format;
DataLine.Info info;
Clip clip;
stream = AudioSystem.getAudioInputStream(yourFile);
format = stream.getFormat();
info = new DataLine.Info(Clip.class, format);
clip = (Clip) AudioSystem.getLine(info);
clip.open(stream);
clip.start();
}
catch (Exception e) {
//whatevers
}
Shortest form (without having to install random libraries) ?
public static void play(String filename)
{
try
{
Clip clip = AudioSystem.getClip();
clip.open(AudioSystem.getAudioInputStream(new File(filename)));
clip.start();
}
catch (Exception exc)
{
exc.printStackTrace(System.out);
}
}
The only problem is there is no good way to make this method blocking to close and dispose the data after *.wav finishes.
clip.drain()
says it's blocking but it's not. The clip isn't running RIGHT AFTER start()
.
The only working but UGLY way I found is:
// ...
clip.start();
while (!clip.isRunning())
Thread.sleep(10);
while (clip.isRunning())
Thread.sleep(10);
clip.close();
