AudioStreaming mic to RTP server using java

I'd like to stream my microphone live to an rtp server which spread the stream to other clients.
It looks like someone tried this here 2 years ago. I tested the Client.java and Server.java, but the described problem in his Client.java still exists, no working microphone.

System.out.println("Line matching " + info + " not supported.");
return;
}
try
{
line = (TargetDataLine) AudioSystem.getLine(info);
int buffsize = line.getBufferSize()/5;
buffsize += 512;
line.open(format);
line.start();

while (true) {
// Read the next chunk of data from the TargetDataLine.
numBytesRead = line.read(data, 0, data.length);
// Save this chunk of data.
dgp = new DatagramPacket (data,data.length,addr,50005);
socket.send(dgp);

I found that someone else got an working microphone client here, but it's just for local playback. What's the difference there so the microphone is working? I am new to java and cannot figure it out actually.

How to play a mono sound with Java in a 4.0 speakers configuration

I need to play a .wav mono file in Java (possibly preloading it in RAM) to all the speakers of a 4.0 speakers configuration. I also need to adjust the volume of each of the channels independently while the audio is playing, leaving the system volume unchanged.
This is my current code. It's nowhere near what I need.
How can I do that? Thanks.

Send audio over UDP

So, I was looking for a microphone data sending tut, but I haven't found any.
So I read Oracles tut about line opening and I am able to record the audio to a ByteArrayOutputStream, but now I have 2 problems!
First:
How to play the recorded audio.
Second: if I am recording it to a BAOS how would i dynamically send it.
I suppose I would send the data array, but would it be too processor hoggy to write to a BAOS every time I recieve it, or could I do it differently?
Current code:
import java.io.ByteArrayOutputStream;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.TargetDataLine;
public class MicrophoneRecorder {
static boolean stopped = false;
public static void main(String[] args) {
AudioFormat format = new AudioFormat(8000.0f, 16, 1, true, true);
TargetDataLine line = null;
DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
if (!AudioSystem.isLineSupported(info)) {
System.out.println("Not supported!");
}
try {
line = (TargetDataLine) AudioSystem.getLine(info);
line.open(format);
} catch (LineUnavailableException ex) {
ex.printStackTrace();
}
ByteArrayOutputStream out = new ByteArrayOutputStream();
int numBytesRead = 0;
byte[] data = new byte[line.getBufferSize() / 5];
line.start();
new Thread(new Runnable() {
#Override
public void run() {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
stopped = true;
}
}).start();
while (!stopped) {
numBytesRead = line.read(data, 0, data.length);
out.write(data, 0, numBytesRead);
}
}
}
Thanks for any help given.
Sincerely, Roberto Anić Banić

Seen this, doesn't work http://javasolution.blogspot.com/2007/04/voice-chat-using-java.html

How to play .wav files in java without lag for games

I have a game that I want to play audio in. What I want to be able to do is that I should be able to declare a ClipPlayer object with the arguments of a path name. Then the constructor should be able to load the sound and then I can just make a call with that object so it won't lag. This is the code that I am using currently for sound:

Declare, load and cache the sounds as class attributes. Then when it is time to hear them, play them in a Clip.

How to play .wav files with java

I am trying to play a *.wav file with Java. I want it to do the following:
When a button is pressed, play a short beep sound.
I have googled it, but most of the code wasn't working. Can someone give me a simple code snippet to play a .wav file?

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();

You can use an event listener to close the clip after it is played
import java.io.File;
import javax.sound.sampled.*;
public void play(File file)
{
try
{
final Clip clip = (Clip)AudioSystem.getLine(new Line.Info(Clip.class));
clip.addLineListener(new LineListener()
{
#Override
public void update(LineEvent event)
{
if (event.getType() == LineEvent.Type.STOP)
clip.close();
}
});
clip.open(AudioSystem.getAudioInputStream(file));
clip.start();
}
catch (Exception exc)
{
exc.printStackTrace(System.out);
}
}

The snippet here works fine, tested with windows sound:
public static void main(String[] args) {
AePlayWave aw = new AePlayWave( "C:\\WINDOWS\\Media\\tada.wav" );
aw.start();
}

A class that will play a WAV file, blocking until the sound has finished playing:
class Sound implements Playable {
private final Path wavPath;
private final CyclicBarrier barrier = new CyclicBarrier(2);
Sound(final Path wavPath) {
this.wavPath = wavPath;
}
#Override
public void play() throws LineUnavailableException, IOException, UnsupportedAudioFileException {
try (final AudioInputStream audioIn = AudioSystem.getAudioInputStream(wavPath.toFile());
final Clip clip = AudioSystem.getClip()) {
listenForEndOf(clip);
clip.open(audioIn);
clip.start();
waitForSoundEnd();
}
}
private void listenForEndOf(final Clip clip) {
clip.addLineListener(event -> {
if (event.getType() == LineEvent.Type.STOP) waitOnBarrier();
});
}
private void waitOnBarrier() {
try {
barrier.await();
} catch (final InterruptedException ignored) {
} catch (final BrokenBarrierException e) {
throw new RuntimeException(e);
}
}
private void waitForSoundEnd() {
waitOnBarrier();
}
}

Another way of doing it with AudioInputStream:
import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.Line;
import javax.sound.sampled.LineEvent;
import javax.sound.sampled.LineListener;
import javax.swing.JDialog;
import javax.swing.JFileChooser;
public class CoreJavaSound extends Object implements LineListener {
File soundFile;
JDialog playingDialog;
Clip clip;
public static void main(String[] args) throws Exception {
CoreJavaSound s = new CoreJavaSound();
}
public CoreJavaSound() throws Exception {
JFileChooser chooser = new JFileChooser();
chooser.showOpenDialog(null);
soundFile = chooser.getSelectedFile();
System.out.println("Playing " + soundFile.getName());
Line.Info linfo = new Line.Info(Clip.class);
Line line = AudioSystem.getLine(linfo);
clip = (Clip) line;
clip.addLineListener(this);
AudioInputStream ais = AudioSystem.getAudioInputStream(soundFile);
clip.open(ais);
clip.start();
}
public void update(LineEvent le) {
LineEvent.Type type = le.getType();
if (type == LineEvent.Type.OPEN) {
System.out.println("OPEN");
} else if (type == LineEvent.Type.CLOSE) {
System.out.println("CLOSE");
System.exit(0);
} else if (type == LineEvent.Type.START) {
System.out.println("START");
playingDialog.setVisible(true);
} else if (type == LineEvent.Type.STOP) {
System.out.println("STOP");
playingDialog.setVisible(false);
clip.close();
}
}
}

A solution without java reflection DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat)
Java reflection decrease performance.
to run: java playsound absoluteFilePathTo/file.wav
import javax.sound.sampled.*;
import java.io.*;
public class playsound {
public static void main (String args[]) throws Exception {
playSound (args[0]);
}
public static void playSound () throws Exception {
AudioInputStream
audioStream = AudioSystem.getAudioInputStream(new File (filename));
int BUFFER_SIZE = 128000;
AudioFormat audioFormat = null;
SourceDataLine sourceLine = null;
audioFormat = audioStream.getFormat();
sourceLine = AudioSystem.getSourceDataLine(audioFormat);
sourceLine.open(audioFormat);
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) {
int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
}
}
sourceLine.drain();
sourceLine.close();
}
}

You can use AudioStream this way as well:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;
public class AudioWizz extends JPanel implements ActionListener {
private static final long serialVersionUID = 1L; //you like your cereal and the program likes their "serial"
static AudioWizz a;
static JButton playBuddon;
static JFrame frame;
public static void main(String arguments[]){
frame= new JFrame("AudioWizz");
frame.setSize(300,300);
frame.setVisible(true);
a= new AudioWizz();
playBuddon= new JButton("PUSH ME");
playBuddon.setBounds(10,10,80,30);
playBuddon.addActionListener(a);
frame.add(playBuddon);
frame.add(a);
}
public void actionPerformed(ActionEvent e){ //an eventListener
if (e.getSource() == playBuddon) {
try {
InputStream in = new FileInputStream("*.wav");
AudioStream sound = new AudioStream(in);
AudioPlayer.player.start(sound);
} catch(FileNotFoundException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
}
}
}

I took #greenLizard's code and made it more robust.
I closed the AudioInputStream.
I used a BufferedInputStream. The AudioSystem getAudioInputStream was throwing an occasional IOException because the getAutoInputSytream method couldn't back up the input stream and start over.
Hopefully, there are no more exceptions to be found.
Here's the modified code. The ErrorDisplayDialog shows an exception as a JDialog in a Java Swing application. Just replace with e.printStackTrace();.
private void playWavFile(String fileName) {
InputStream inputStream = getClass().getResourceAsStream(fileName);
BufferedInputStream bufferedInputStream = new BufferedInputStream(
inputStream);
AudioInputStream audioStream = null;
AudioFormat audioFormat = null;
try {
audioStream = AudioSystem.getAudioInputStream(bufferedInputStream);
audioFormat = audioStream.getFormat();
} catch (UnsupportedAudioFileException e) {
new ErrorDisplayDialog(view.getFrame(),
"UnsupportedAudioFileException", e);
return;
} catch (IOException e) {
new ErrorDisplayDialog(view.getFrame(), "IOException", e);
return;
}
DataLine.Info info = new DataLine.Info(SourceDataLine.class,
audioFormat);
SourceDataLine sourceLine;
try {
sourceLine = (SourceDataLine) AudioSystem.getLine(info);
sourceLine.open(audioFormat);
} catch (LineUnavailableException e) {
new ErrorDisplayDialog(view.getFrame(), "LineUnavailableException",
e);
return;
}
sourceLine.start();
int nBytesRead = 0;
byte[] abData = new byte[128000];
while (nBytesRead != -1) {
try {
nBytesRead = audioStream.read(abData, 0, abData.length);
} catch (IOException e) {
new ErrorDisplayDialog(view.getFrame(), "IOException", e);
return;
}
if (nBytesRead >= 0) {
sourceLine.write(abData, 0, nBytesRead);
}
}
sourceLine.drain();
sourceLine.close();
try {
audioStream.close();
} catch (IOException e) {
new ErrorDisplayDialog(view.getFrame(), "IOException", e);
}
}
