Jason Arena has us at it again, making crazy stuff. This time around I am using Processing again (It’s just so much fun) and will be using an electric guitar as an input device. It is simple to set up and required me only to buy a 6′ male to male stereo 1/4″ jack wire and find a 9 volt battery to repair a headphone amplifier. The electric guitar outputs to the headphone amp, which then outputs to the mic input of my laptop. Then, using the Sonia library, I take that data and do whatever I want. As of now I am working on note detection, which cannot be done though pitch so I have to analyze the frequency spectrum. I’ll have a video up shortly demonstrating it.
