Haha, I wonder what kind of debugging you're into. XD

Great idea

This hilarious! thanks!

This is cool stuff, thank you for sharing!

I can never hear my websites the same way again. I need to release these souls from their agony.

Sounds beautiful, love it

wow! I like it

Make a browser extensions before somebody else does. Take the credit! cool stuff!

I can never hear my websites the same way again. I need to release these souls from their agony.

True that!

Brilliant!

very smart !!!

Change that stop delay on line 22 to 0.03 on Facebook and SUDDENLY I'M IN THE FUTURE.

This is absolutely brilliant. And useful.

Here's a funny variation that speaks out the counts in different pitches/rates

const speechSynthesis = window.speechSynthesis
const min = 0
const max = 100
const bad = 15 // just a random max to enable 'bad developer' mode

const observer = new MutationObserver(function(mutationsList) {
  const msg = new SpeechSynthesisUtterance()
  const len = mutationsList.length
  
  if (len > bad) {
    msg.text = 'Bad Developer'
  } else {
    const n = len > max ? max : len
    const pitch = ((n - min) / (100 - min)) * 2
    msg.text = len
    msg.rate = 4 - pitch * 4
    msg.pitch = 2 - (pitch * 1.6 * 1.2)
  }

  speechSynthesis.speak(msg)
})

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

Can anyone upload what they hear on some sites?

Hahaha, great work!

You'll just hear a Chewbacca Jr. talking

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

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.

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,
})  

Genius!

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

Absolutely wonderful!

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

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

try this on a typing test website. very enjoyable lol

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.

Wow this is probably the best gist I've ever seen

love this

This one's great~

Awesome idea!

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

@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.

@R4meau, that's awesome!

Maybe someone makes some chrome extension?

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})})();

Maybe someone makes some chrome extension?

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

@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.

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

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