access to recorded data while recording?

[dreamix]

i have a player that records audio into a ByteArrayOutputStream. is it possible to access this bytearray every n recorded bytes or seconds and do some calculations with it? right now the problem is i have to call rc.commit() in order to do so, but this stops the entire recording process and i'd have to start again, which i dont want since then there will be gaps between the recordings.

to get a picture, here's the idea:

// initialize and start recording
while (!quit)
{
	this.sleep(500);

	// do some stuff with the recorded data so far - in another thread

	// reset output bytearray so it can be filled with new data
}
