Voice input generating 3d form

Hi, I am quiet interested in the theme generating/affecting 3d form by voice input. I have seen some examples in the this forum e.g. Luis Fraguada great example gHowlLiveAudio2 . Do anybody know a tutorial or dislike, which describes the way of doing such kind of work in a very basic and simple way step for step, - since I am new to grasshopper and processing, - and to make these two applications work together.

I am planning to use my voice as input by the microphone, Ghowl/Udp and processing, but other approaches could be used as well.  

Hope one of you have an approach to recommend. Thanks.
