I am wondering if it is possible to have mic input from multiple users at the same time? Also is there an official name for the thing that I am trying to do?

Here is a little sketch that I made from some examples on the p5.js website and a little of my own code to make the ball more responsive:

function setup(){  
let cnv = createCanvas(600, 300);  
cnv.mousePressed(userStartAudio);  
mic = new p5.AudioIn();  
mic.start();  
}

function draw(){  
background(70, 80, 20);  
fill(255);  
text(‘tap to start’, 10, 20);

micLevel = mic.getLevel();  
let y = height - 20 \* micLevel \* height;  
ellipse(width/2, y-19, 40, 40);  
}

Sure, and there are multiple ways to skin the cat. One possible solution is [WebRTC (Web Real Time Communication)](https://developer.mozilla.org/en-US/docs/Web/API/WebRTC_API). I’m not sure that there’s a quick and beginner-friendly option out there, though.

Are you referring to the live-input-from-multiple-computers-thing? If so, _real-time_ and _peer-to-peer_ (combined with _audio_, _p5.js_, and _javascript_) may turn up interesting results on your favorite search engine.
