isn't audio recording(wav) streamable?

[aluckybird]

Hi dear all,
With WTK22, I am doing audio recording to wav format at client and send it to server by stream. I found out that client will not send any data out until it finish recording by recordControl.commit.
Am I doing something wrong or that's the fact? Any Nokia phone support audio streaming, or should I use other format?

I read from Sun (See below) wav audio format is not streamable since some fields in the header can only be filled after finish recording.
If I want to have the realtime (nearly) audio, what should I do?

Here is my recorder code.

try {
	// Create a DataSource that captures live audio.
	p = Manager.createPlayer("capture://audio");
	p.realize();
    // Get the RecordControl, set the record location, and 
    // start the Player and record for 5 seconds.
    
    rc = (RecordControl)p.getControl("RecordControl");
     rc.setRecordStream(outputStream);
    debugInfo("Set record to out stream");
    rc.startRecord();
	p.start();
				
	try {
		Thread.currentThread().sleep(5000);
	} catch (InterruptedException ie) {
	}
} catch (IOException ioe) {
	ioe.printStackTrace();
} catch (MediaException me) {
	me.printStackTrace();
}
//stopRecorder();

Any suggestions, hint etc will be appreciated.
