I would like to let processing record a sound (microphone) and let it save this as a Boolean Array (?)

In the end it should be something like a morse code (yes /no ) to let the program in the following give me the opportunity of a comparison between the recorded sound and the current microphone input.

Hope you get the basic idea behind it ?!

So my question would be what's the easiest way to record and save a sound in Array?

thanks a lot
