Hey @mattiasu96 – the reason it looks so different than the video demo, is in the video, the sketch is sending audio to an analog oscilloscope – that’s then being recorded. The thickness/color of the line etc, are all dependent on the quality of that oscilloscope, the color coating of the screen and sharpness and intensity of the beam of light. Within Processing, you will only see a dinky little preview for debugging what it will look like. I recommend trying it out with a real analog oscilloscope if you have access to one, but until then, setup something to route your computer audio within itself (if on a mac, check out Blackhole ) – then view the sketch using Hansi Raber’s Oscilloscope. It will get you very close to the real thing and must nicer results than the preview within Processing.
