16 bit stereo question

Question

Hi, I'm converting mp3 to wav then modifying the wav and saving it to a new wav file. The saved wav files comes out as 16 bit mono. I need it to be 16 bit stereo like the original. I realize the following code does not account for the stereo (only 4 channels), but if someone could point out how I can correct it so the saved wav is stereo I would appreciate it. Thanks.

if(numChan==4) {
   try {                          
      for (int r=0; r < audioByteData.length-4; r+=4) {
         loByte = audioByteData[r+0];                
         hiByte = audioByteData[r+1];
         //convert bytes to int
         sample = (hiByte << 8) | (loByte & 0x00FF);
         //raw audio sample array                
         audioInData[r/4] = (short)sample;  
   } catch (Exception ex){ex.printStackTrace();}                 
}

Hi
I have tried your vis and they run fine. In the stereo one, think you are selecting columm 1 for the two spectrums ( same channel), and one should be 0.
See attached file.
Sorry. Signal was 1000 Hz square
Check the windows mixer settings to see they are correct.
Hope it helps
Alipio.
