Apps Help with voice recording

[Davidb93]

Hi all,
I trying to write app that record voice and send it through tcp socket.
Currently i succeed to record voice to sd card. My problem is that the recording buffer works only for short [] but in order to send it through the socket i should convert it to bytes. When i am trying to convert the short [] to byte i get only noise in the created file on sd card.
Can some one help me to do it ??
This is my code:

import android.os.Bundle;
import android.os.Environment;
import android.app.Activity;
import android.media.AudioFormat;
import android.media.AudioRecord;
import android.media.MediaRecorder;

import java.io.BufferedOutputStream;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;


public class MainActivity extends Activity 
{
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) 
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		Recorder recorderInstance = new Recorder();
		Thread th = new Thread(recorderInstance);
		recorderInstance.setFileName(
				new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/my2.pcm"));
		th.start();
		recorderInstance.setRecording(true);
		synchronized (this) 
		{
			try 
			{				
				this.wait(20000);
			
			} 
			catch (InterruptedException e) 
			{
				e.printStackTrace();
			}
		}
		recorderInstance.setRecording(false);
		try 
		{
			th.join();
		} catch (InterruptedException e) 
		{
			e.printStackTrace();
			
		}
	}
}


class Recorder implements Runnable 
{
	private int frequency;
	private int channelConfiguration;
	private volatile boolean isPaused;
	private File fileName;
	private volatile boolean isRecording;
	private final Object mutex = new Object();
	// Changing the sample resolution changes sample type. byte vs. short.
	private static final int audioEncoding = AudioFormat.ENCODING_PCM_16BIT;

	/**

	 */
	public Recorder() {
		super();
		this.setFrequency(11025);
		this.setChannelConfiguration(AudioFormat.CHANNEL_CONFIGURATION_MONO);
		this.setPaused(false);
	}

	public void run() 
	{
		// Wait until we
