Hahaha great idea! 👍 (could be a nice prank too)
Didn't work on Firefox, but Chrome is ✔️

nickdotht · 2020-02-16T15:45:11Z

I honestly didn't like it at first, then I realized how useful it can actually be :) . So I turned it into a basic Chrome extension: https://github.com/R4meau/plink-plonk

I'll be working on it every Sunday (very slow for now) and I'm open for any contributions at any time. Thanks for the head start @tomhicks.

iAnatoly · 2020-02-16T17:29:00Z

I have moved out the constants into variables, to be able to play with the settings more easily.
I also added a random component. to make it sound less monotonous:

// origin: https://gist.github.com/tomhicks/6cb5e827723c4eaef638bf9f7686d2d8 ,  tomhicks/plink-plonk.js

const audioCtx = new (window.AudioContext || window.webkitAudioContext)()
var delay = 0.03
var freqbase = 600
var freqrnd = 400
const observer = new MutationObserver(function(mutationsList) {
  const oscillator = audioCtx.createOscillator()

  oscillator.connect(audioCtx.destination)
  oscillator.type = "sine"
  oscillator.frequency.setValueAtTime(
    Math.log(mutationsList.length + 5) * (Math.random()*freqrnd + freqbase),
    audioCtx.currentTime,
  )

  oscillator.start()
  oscillator.stop(audioCtx.currentTime + delay)
})

observer.observe(document, {
  attributes: true,
  childList: true,
  subtree: true,
  characterData: true,
})

Then you can play with delay and freq on the fly.

Love this!

This one randomly decreases/increases tone until it reaches a threshold. Makes it a bit more harmonious:

// origin: https://gist.github.com/tomhicks/6cb5e827723c4eaef638bf9f7686d2d8 ,  tomhicks/plink-plonk.js

const audioCtx = new (window.AudioContext || window.webkitAudioContext)()
var delay = 0.03
// parameters of the random increment/decrement
var freqstart = 600
var freqlow = 400
var freqhigh = 900
var freqspeed = 50
// initial values
var freqinc = 25
var freq = 600

const observer = new MutationObserver(function(mutationsList) {
  const oscillator = audioCtx.createOscillator()

  oscillator.connect(audioCtx.destination)
  oscillator.type = "sine"
  oscillator.frequency.setValueAtTime(
    Math.log(mutationsList.length + 5) * freq,
    audioCtx.currentTime,
  )
  freq += freqinc
  if (freq > freqhigh || freq<freqlow) {
    // reset if we have reached the high or low bound
    freq = freqstart
    freqinc = (Math.random()-0.5)*freqspeed
  }

  oscillator.start()
  oscillator.stop(audioCtx.currentTime + delay)
})

observer.observe(document, {
  attributes: true,
  childList: true,
  subtree: true,
  characterData: true,
})

Nice work! Check this out https://soundcode.now.sh too 🙂

ttcremers · 2020-02-17T08:15:55Z

Absolutely wonderful! 😄

awesome! My computer now sounds like one from a '70s TV serial

soundmasteraj · 2020-02-17T13:29:59Z

Could replace the pulses with Rice Krispies sounds. Now, web == tasty breakfast!

ricokahler · 2020-02-18T04:53:41Z

try this on a typing test website. very enjoyable lol

MarkArts · 2020-02-18T12:57:31Z

Added quantization and randomness + delay for a cuter effect 😇

Deploy this on production but use an Arnold Schwarzenegger sound bank which plays a random line at each DOM mutation.

everaldo · 2020-02-19T21:50:56Z

Awesome idea!

It would be nice to create some debugging library with sounds for Ajax Requests, Ajax failures, console errors etc.

nickdotht · 2020-02-19T22:15:12Z

@everaldo I'm working on it at the moment: https://github.com/r4meau/plink-plonk

Also, great idea about the console errors. Added this to the list of features in the README :). For the requests, it's already in the list.

everaldo · 2020-02-19T22:37:52Z

@R4meau, that's awesome!

Adrinalin4ik · 2020-02-20T07:39:47Z

Maybe someone makes some chrome extension?

AlexRatmansky · 2020-02-20T11:06:10Z

And the bookmarklet version:

javascript:(function(){const%20audioCtx=new(window.AudioContext||window.webkitAudioContext);const%20oscillator=audioCtx.createOscillator();oscillator.connect(audioCtx.destination);oscillator.type="sine";let%20numItems=0;oscillator.frequency.setValueAtTime(1,audioCtx.currentTime);oscillator.start();const%20observer=new%20MutationObserver(function(mutationsList){numItems+=mutationsList.length;oscillator.frequency.setValueAtTime(Math.log(numItems+1)*440,audioCtx.currentTime);setTimeout(()=>{numItems-=mutationsList.length;if(numItems===0){oscillator.frequency.setValueAtTime(1,audioCtx.currentTime)}else{oscillator.frequency.setValueAtTime(Math.log(numItems+1)*440,audioCtx.currentTime)}},100)});observer.observe(document,{attributes:true,childList:true,subtree:true,characterData:true})})();

aibolik · 2020-02-21T12:54:18Z

Yeah, let's do it... (adding to backlog) 😅

nickdotht · 2020-02-21T13:00:33Z

@aibolik Already in the making: https://github.com/r4meau/plink-plonk

Feel free to fork and contribute... or start your own. 😄

I'm gonna go slow on it for now (Sunday only), but I'll accept useful PRs at anytime.

mahnouel · 2020-02-28T09:50:20Z

Could anyone add reload support? This is so wonderful 🥰 Maybe via localStorage? Or as Firefox Extension?

iamnmanoj · 2020-03-04T11:53:28Z

Its so helpful to find out the DOM manipulations happening behind the eyes!!. Good job @R4meau
