Testing Code :
Its better to use gui rather than console to record sound (due to thread start/stop problem)
Here is my console test application for sound record and save:

 public class Testss {  
   public static void main(String[] args) throws Exception {  
     //MicrophoneRecorder mr = new MicrophoneRecorder(AudioFormatUtil.getDefaultFormat());  
     MicrophoneRecorder mr = new MicrophoneRecorder( YOU NEED TO PASS OBJECT OF AudioFormat here); 
     mr.start();  
     Thread.sleep(2000);  
     mr.stop();  
     //save  
     WaveData wd = new WaveData();  
     Thread.sleep(3000);  
     wd.saveToFile("~tmp", Type.WAVE, mr.getAudioInputStream());  
   }  
 }  

Code for saving AudioInputStream in WaveData Class : (Full Code Next Time)
   public boolean saveToFile(String name, AudioFileFormat.Type fileType,  
                AudioInputStream audioInputStream) {  
     System.out.println("Saving...");  
     if (null == name || null == fileType || audioInputStream == null) {  
       return false;  
     }  
     File myFile = new File( name+"." + fileType.getExtension());  
     // reset to the beginnning of the captured data  
     try {  
       audioInputStream.reset();  
     } catch (Exception e) {  
       return false;  
     }  
     int i = 0;  
     while (myFile.exists()) {  
       String temp = "" + i + myFile.getName();  
       myFile = new File(temp);  
     }  
     try {  
       AudioSystem.write(audioInputStream, fileType, myFile);  
     } catch (Exception ex) {  
       return false;  
     }  
     System.out.println("Saved " + myFile.getAbsolutePath());  
     return true;  
   }
