Preciso de ajuda processing audio desenho

I need to develop a processing.js code that allows anyone to speak through the microphone to draw anything on the screen in a random, colorful way. Here’s an example: https://www.openprocessing.org/sketch/579128

Please someone help me, how to develop it? Can I pay symbolically if someone sends me the code
