Extra bytes problem with audio capture,j2me

Question

hi there
I m working on a J2ME application that captures live audio through microphone into a bytearrayoutputstream .
i have supplied the capture time,sampling rate, bits per sample, no of channels info to the program.
but when i check out the size of the byte array , i see that its greater than what it should be !!!
if the size had been lesser than expected, i could guess that sum bytes are getting lost , but what attributes to the larger size.
and everytime i run the program i c that the size is larger than expected though the number by which it exceeds is different everytime.
can ne one help??

Hi,
Thank you very much for your help. I changed the code as you suggested. It minimizes the gap, but there is still part of missing voices.
When you tried it, did you get really perfect (no gap) recording, as if it was recorded to one single stream?
below is my recording code:
for(int i=0;i<types.length;i++) {
               rc.setRecordStream(baos);
rc.startRecord();
Thread.sleep(2000);
rc.stopRecord();
rc.commit();
init.append("baos size after rec:" + baos[i].size()+"\n");
}//end of for
p.stop();
p.close();
and here is the code for playing back the voice:
for(int i=0;i<3;i++) {
            bais[i] = new ByteArrayInputStream(baos.toByteArray());
try {
p = Manager.createPlayer(bais[i],types[i]);
p.prefetch();
p.start();
Thread.sleep(p.getDuration());
p.stop();
p.close();
catch(Exception e) {
init.append("exception in playing back voice: "+e.toString()+"\n");
e.printStackTrace();
for playing back, we need to stop and close the player first, then create a new player to play the next input stream, dont we?
Thanks
