I wanted to try out the FFT class in processing.  
The example code did not work, as it wasn’t showing any result.  
A slight variation showed that the AudioIn did in fact get Information also I was checking the amplitude. It was around 1.5E-5.

Does anyone know how to fix that?

And the input is analog audio?

Can you record the input, does it work?
