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](https://www.openprocessing.org/sketch/579128)
Please someone help me, how to develop it? Can I pay symbolically if someone sends me the code
Thankss

you have the example, it is in old version p5.js ( 0.5.11 )
but here copy to
[https://editor.p5js.org/kll/sketches/LN-x1Go8r](https://editor.p5js.org/kll/sketches/LN-x1Go8r)
it runs also under newest 0.9.0

so what was your question?
you understand the concept?
-a- sound input from mic
-b- FFT getEnergy
-c- curveVertex

Hey kll, thank you so much!
But I can’t run the project in the browser when I play Processing. And I would need that.
Do you have any suggestion?
In the first image, it’s me running the project in processing:
In the second image, this is what appears when I click on “run”, it does not load the project, the whole page is blank:
