measuring signal from microphone

Thread view:

I have managed to get a small application to record a sample from the
microphone and save it to file using AudioSystem.write. But I would
like to be able to read some samples from the audio before it is saved
to disk so that I can check whether the microphone is connected
properly and display this to the user. How can this be done?

Thanks

Why not offer the user an oscilloscope trace?

(The jar is an executable form of AudioTrace.java)
