create a crypted voip application

I realized a voip application encrypted with the algorithms AES and RC4 then when I execute the application and I encrypt the voice with the two algorithms it works normal but when I add the algorithm ECC it works for the first time and after it displays this error and then nothing of these algorithms works
here is some of my code that executes voice transfer and encrypted with ECC

How can I print sound as byte array? or int array?

I'm making anti-phase sound with java.(anti-phase is reflected wave. x-coordinate is not changed, but y-coordinate is upside down.)
Before reflecting sound wave, I have to get byte array(or int array) from sound.
I get sound from microphone of my laptop.
Here is my CODE(I got original code, which record sound as file, in web. I modified it little)
public class NoiseController extends Thread{
private TargetDataLine line;
private AudioInputStream audioInputStream;
public NoiseController(TargetDataLine line) {
this.line = line;
this.audioInputStream = new AudioInputStream(line);
}
public void start() {
line.start();
super.start();
}
public void stopRecording() {
line.stop();
line.close();
}
public void run() {
try {
int packet;
while((packet = audioInputStream.read()) != -1)
System.out.println(packet);
}
catch(IOException ioe) {
ioe.getStackTrace();
}
}
public static void main(String[] args) {
AudioFormat audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100.0F, 16, 2, 4, 44100.0F, false);
DataLine.Info info = new DataLine.Info(TargetDataLine.class, audioFormat);
TargetDataLine targetDataLine = null;
try {
targetDataLine = (TargetDataLine)AudioSystem.getLine(info);
targetDataLine.open(audioFormat);
}
catch(LineUnavailableException lue) {
out("unable to get a recording line");
lue.printStackTrace();
System.exit(-1);
}
AudioFileFormat.Type targetType = AudioFileFormat.Type.WAVE;
NoiseController recorder = new NoiseController(targetDataLine);
System.out.println(targetDataLine);
System.out.println(targetType);
out("Press ENTER to start the recording.");
try {
System.in.read();
}
catch(IOException ioe) {
ioe.printStackTrace();
}
recorder.start();
out("Recording...");
out("Press ENTER to stop the recording.");
try {
System.in.read();
System.in.read();
}
catch(IOException ioe) {
ioe.getStackTrace();
}
recorder.stopRecording();
out("Recording stopped.");
}
private static void out(String msg) {
System.out.println(msg);
}
}
However, Console doesn't print anything while recording...
It shows just
com.sun.media.sound.DirectAudioDevice$DirectTDL#25154f_
WAVE
Press ENTER to start the recording.
Recording...
Press ENTER to stop the recording.
Recording stopped.
If I edit run() like AudioSystem.write(stream, fileType, out);
instead of
int packet;
while((packet = audioInputStream.read()) != -1)
System.out.println(packet);
program saves wav file.
What is wrong in my program?
you are not printing the Exception as Uwe Allner said.
I´ve also try to correct it and I think the result must be like this:
public class NoiseController extends Thread {
private final TargetDataLine line;
private final AudioInputStream audioInputStream;
public NoiseController(final TargetDataLine line) {
this.line = line;
this.audioInputStream = new AudioInputStream(line);
}
#Override
public void start() {
line.start();
super.start();
}
public void stopRecording() {
line.stop();
line.close();
try {
audioInputStream.close();
} catch (final IOException e) {
e.printStackTrace();
}
}
#Override
public void run() {
try {
final int bufferSize = 1024;
int read = 0;
final byte[] frame = new byte[bufferSize];
while ((read = audioInputStream.read(frame)) != -1 && line.isOpen()) {
// only the first read bytes are valid
System.out.println(Arrays.toString(frame));
}
} catch (final IOException ioe) {
ioe.printStackTrace();
}
}
public static void main(final String[] args) {
final AudioFormat audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100.0F, 16, 2, 4, 44100.0F, false);

}
final AudioFileFormat.Type targetType = AudioFileFormat.Type.WAVE;
final NoiseController recorder = new NoiseController(targetDataLine);
System.out.println(targetDataLine);
System.out.println(targetType);

try {

Simulate microphone Input

I am trying to write a little program that reads a wav file and sends the output as if it would come from my microphone. Unfortunately I do not have much experience with the sound API.
Background: What I am basically trying to realize is a program that plays a sound while I am in a voicechat (i.e Teamspeak, Ventrilo). To get that to work now I would have to switch the recording device to "What you hear", play the sound and then switch back to microphone. The program should simulate input from the microphone.
So far I could not get any further than just playing the sound. I guess I just need a different SourceLine?
public class Player {
private final int BUFFER_SIZE = 128000;
private AudioInputStream audioStream;
private AudioFormat audioFormat;
private SourceDataLine sourceLine;
public void playSound(File soundFile) {
try {
audioStream = AudioSystem.getAudioInputStream(soundFile);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
audioFormat = audioStream.getFormat();
DataLine.Info infoIn = new DataLine.Info(SourceDataLine.class,
audioFormat);
try {
sourceLine = (SourceDataLine) AudioSystem.getLine(infoIn);
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();
}
}
Solution:
Install VB Audio Cable (http://vb-audio.pagesperso-orange.fr/Cable/). It's donationware. Make VB-Output standard recording device. In the microphone properties choose VB-Input as playback.
public class Player {
private final int BUFFER_SIZE = 128000;
private AudioInputStream audioStream;
private AudioFormat audioFormat;
private SourceDataLine sourceLine;
public void playSound(File soundFile) {
try {
audioStream = AudioSystem.getAudioInputStream(soundFile);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
audioFormat = audioStream.getFormat();
DataLine.Info infoIn = new DataLine.Info(SourceDataLine.class,
audioFormat);
try {
Mixer.Info[] mixerInfos = AudioSystem.getMixerInfo();
Mixer mixer = null;
for (int i = 0; i < mixerInfos.length; i++) {
System.out.println(mixerInfos[i].getName());
if (mixerInfos[i].getName().equals(
"CABLE Input (VB-Audio Virtual Cable)")) {
mixer = AudioSystem.getMixer(mixerInfos[i]);
break;
}
}
sourceLine = (SourceDataLine) mixer.getLine(infoIn);
sourceLine.open(audioFormat);
} catch (LineUnavailableException 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();
}
}
You can install some program like Virtual Audio Cable and from your music player redirect playing sound to virtual input. In your program you must listen that virtual input source and you can for test redirect to normal headphones or speaker received signal or saved it to file.

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:
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;

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

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