I'm racking my brain in order to solve a knotty problem (at least for me).

While playing an audio file (using Java) I want the signal amplitude to be displayed against time.

I mean I'd like to implement a small panel showing a sort of oscilloscope (spectrum analyzer). The audio signal should be viewed in the time domain (vertical axis is amplitude and the horizontal axis is time).

Does anyone know how to do it? Is there a good tutorial I can rely on? Since I know very little about Java, I hope someone can help me.
