How to draw a graph of sounds while recording in java sound?

问题

I successfully recording java sounds from my micro phone and can draw the recorded wave file graph as in attached image. (I have tried to upload image from here a lot, but it is failed every time.i also used tinypic also but failed in uploading , i think there is some error in my internet connection, i will upload it later here. )

I am also attaching all my code. http://pastebin.com/EgW2ZcyJ

Now, my question is i want to display Graphs for the sound while recording in real time .so if i try to read audio input stream which is used in recording in new thread and sleep this thread for 1 seconds until the recording is finished . but in this approach it gives frame length -1 so nothing can be drawn.

so how can i draw a graph means how can i get frames of recorded sound [bytes from audio input stream] while recording in real time , so i can use it to draw a graph using it in different thread so i can exactly simulate what window's sound recorder provides ??

Thank You Mihir Parekh

This example uses JFreeChart to display recent changes to a time-based series.

Sorry, but you don't understand my question.

Addedndum: You can edit your question to clarify; this will also help guide future answers. In the interim, you might be able to adapt TeeOutputStream to intercept the OutputStream from AudioSystem.write().
