Java Sound API unable to stop recording on a button click from UI of a web Application

I am using Java Sound API for creating a Web Application .User Interface(UI) has a button which on click starts recording the speech ,the recorded audio is saved in an audio file (.wav ext) .UI also has a play button which accesses the same audio file and plays the recording back.
Currently I am recording the audio for a specified duration which is hardcoded in my application or getting passed from UI as a parameter while the recording starts.But now the requirement is to stop the recording on click of a button on UI.
Now the issue is while capturing the audio I am opening a targetline using below code :
public void capture(int record_time)
{
try {
AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100, 16, 2, 4, 44100, false);
DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
if(!AudioSystem.isLineSupported(info))
{
System.out.println("Line not supported");}
final TargetDataLine targetDataLine = (TargetDataLine)AudioSystem.getLine(info);
targetDataLine.open();
targetDataLine.start();
Thread thread = new Thread()
{
#Override public void run()
{
AudioInputStream audioStream = new AudioInputStream(targetDataLine);
File audioFile = new File(fileName);
System.out.println("Recording is going to get saved in path :::: "+ audioFile.getAbsolutePath());
try{
AudioSystem.write(audioStream, AudioFileFormat.Type.WAVE, audioFile);
}
catch (IOException e){
e.printStackTrace();
}
System.out.println("Stopped Recording");
}
};
thread.start();
Thread.sleep(record_time*1000);
targetDataLine.stop();
targetDataLine.close();
System.out.println("Ended recording test");
} catch (LineUnavailableException e) {
System.err.println("Line unavailable: " + e);
System.exit(-2);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Above code will stop recording once the record time is elapsed.
But I want another method like below which when invoked from jsp (stop button click) should be able to get the same targetline object which is responsible for current recording and stop the current recording.
Below code does not work for me and recording goes on
public void stop(){
try{
System.out.println("stop :: in stop");
AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100, 16, 2, 4, 44100, false);
DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
if(!AudioSystem.isLineSupported(info))
{
System.out.println("Line not supported");}
final TargetDataLine targetDataLine = (TargetDataLine)AudioSystem.getLine(info);
System.out.println("stop Recording....");
System.out.println("targetDataLine.getLineInfo() in stop:::::::"+targetDataLine.getLineInfo());
System.out.println("targetDataLine.isActive() in stop:::::::"+targetDataLine.isActive());
System.out.println("targetDataLine.isOpen() in stop:::::::"+targetDataLine.isOpen());
targetDataLine.stop();
targetDataLine.close();
}
catch (Exception e) {
System.err.println("Line unavailable: " + e);
}
}
Please suggest some resolution.
One more thing that might ..not sure but might has some role to play is the way I am calling these methods from my servlet ..below is the code....
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String action = request.getParameter("buttonName");
String record_time = request.getParameter("time");
System.out.println("action:::"+action +"time in minutes:::"+ record_time);
int record_time_int =(Integer.parseInt(record_time));
String fileName = "studentXYZ.wav";
System.out.println("action:::"+action +"----wavfile:::"+fileName+"time in minutes:::"+ record_time);
Recorder01 record = new Recorder01();
if (action != null && (action.equalsIgnoreCase("Capture")) ){
record.capture(fileName, action,record_time_int);
request.setAttribute("fileName", fileName);
request.getRequestDispatcher("/recordAudio.jsp").forward(request, response);
}
else if (action != null && action.equalsIgnoreCase("play")) {
Recorder01 playsound = new Recorder01();
playsound.play(fileName);
System.out.println("finished playing recording");
request.setAttribute("fileName", fileName);
request.getRequestDispatcher("/recordAudio.jsp").forward(request, response);
}
else if(action!=null && action.equalsIgnoreCase("Stop")){
System.out.println("stop recording called");
record.stop();
request.getRequestDispatcher("/recordAudio.jsp").forward(request, response);
}
}

private TargetDataLine targetDataLine;
public void capture() {
if (targetDataLine == null) {
try {

if (!AudioSystem.isLineSupported(info)) {
System.out.println("Line not supported");

Sound loading working in ubuntu but not working in windows

I have written a method in java to play a sound. It works fine on my ubuntu laptop but doesnt work on windows. There is no error but i think it might be bypassing the drain method on windows for some reason.
public static void runOnce(final String location) {
new Thread(new Runnable() {
public void run() {
try {
File audioFile = new File(Game.gameFolder + "/sounds/" + location);
final AudioInputStream audioStream = AudioSystem.getAudioInputStream(audioFile);
AudioFormat format = audioStream.getFormat();
DataLine.Info info = new DataLine.Info(Clip.class, format);
final Clip audioClip = (Clip) AudioSystem.getLine(info);
audioClip.open(audioStream);
audioClip.start();
audioClip.drain();
try {
audioClip.close();
audioStream.close();
} catch (Exception e) {
System.out.println("heyeyeyeyye");
}
System.out.println("sound method ran");
} catch(Exception e) {}
}
}).start();
}
thanks -Tyler
EDIT:
i remember actually it worked on windows before i used drain but after a certain amount of time it wouldnt load anymore so i switched to drain

I suggest you use try-with-resources and that you join() the Thread you start and never swallow the message from your Exception. Something like,
public static void runOnce(final String location) {
File audioFile = new File(Game.gameFolder + "/sounds/" + location);
Thread t = new Thread(new Runnable() {
public void run() {
try (AudioInputStream audioStream = AudioSystem
.getAudioInputStream(audioFile);) {
AudioFormat format = audioStream.getFormat();
DataLine.Info info = new DataLine.Info(Clip.class, format);
try (Clip audioClip = (Clip) AudioSystem.getLine(info);) {
audioClip.open(audioStream);
audioClip.start();
audioClip.drain();
}
System.out.println("heyeyeyeyye");
System.out.println("sound method ran");
} catch (Exception e) {
e.printStackTrace();
}
}
});
t.start();
t.join();
}

extreme lag after having .wav, .au sound in my game?

i tried to search up online there are very limited resources. in the action Performed Method:
actionPerformed(){
---------------
new Sound();}
and in Sound class
public Sound(){
try {
String filePath="path\\file.wav";
File path= new File(filePath);
AudioInputStream stream;
AudioFormat format;
DataLine.Info info;
Clip clip;
stream = AudioSystem.getAudioInputStream(path);
format = stream.getFormat();//becomes formatted
info = new DataLine.Info(Clip.class, format);// info
clip = (Clip) AudioSystem.getLine(info);// casting for clip
clip.open(stream); // clip opens stream with path
clip.start();
}
catch (Exception e) {
System.out.println("errors");
}
}
Thank you.

As per the Javadoc of the .start() method:
Allows a line to engage in data I/O. If invoked on a line that is
already running, this method does nothing. Unless the data in the
buffer has been flushed, the line resumes I/O starting with the first
frame that was unprocessed at the time the line was stopped. When
audio capture or playback starts, a START event is generated.
There is no mention of the audio being played in an asynchronous manner. This means that your sound will be tackled by the thread which calls the start method, which since you are calling it in your event handler, will eventually mean that your Event Dispatching Thread is taking care of playing audio.
This thread is also responsible for drawing stuff on screen, so any other thing that runs on it, audio in your case, will have a negative effect on your rendering.
You could use some code like below (taken from here) to make your audio be played on a separate thread. This should cater for your lagging problems.

You might want to check out the Lightweight Java Game Library's OpenAL bindings.
It worked very nicely for me when I had to write a game with a large number of sound files.
Other than that, Clips are named Clips for a reason; they're supposed to be very brief and very small, as they're loaded instead of streamed in real-time.

How to make sound loop using this method?

I did sound in a REALLY wierd way, do you think that there may be a way to loop it? cuz it only plays once then stops. Here is code for sound:
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.SourceDataLine;
public class Sound {
private final static int BUFFER_SIZE = 12800000;
private static File soundFile;
private static AudioInputStream audioStream;
private static AudioFormat audioFormat;
private static SourceDataLine sourceLine;
/**
*
* #param filename the name of the file that is going to be played
*
*/
public static 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();
}
}
To activate it i do:
new Thread(new Runnable() {
public void run() {
Sound.playSound("hurt.au");
}
}).start();
(if i do just Sound.playSound("hurt.au"); the game freezes because the sound plays on the games main thread so i put the sound in it's own thread to save the game from freezing)
So the question is, how do i loop it?

You will need some sort of test to see whether the sound currently playing is finished or not. If you are making a game, I might suggest using some libraries to make it easier. Such as slick2d. This has inbuilt functions to loop a sound instead of just playing it once. If you choose not to, you will have to keep track of the thread and on every update of your game state look at the sound object and ask the sourceline if it has finished playing or not. If it has then sourceline.start() else no-op. You could also put the thread inside the sound.playsound method itself, thereby making your code a little bit less coupled.

I really recommend using a 3rd party library to make it easier on yourself though.

How can i get beep audio input from mic and process it in java
