Hello,

I’m just learning to work with sound and I can’t get my sketch to work.

Here’s the code:

```auto
let mySound;

function preload() {
  soundFormats('mp3');
  mySound = loadSound('doorbell.mp3');
}

function setup() {
  mySound.setVolume(0.1);
  mySound.play();
}

```

I’m using [openprocessing.org](http://openprocessing.org) as my IDE. I’ve uploaded a file called doorbell.mp3. I get an error that says: “Uncaught ReferenceError: soundFormats is not defined”  
How do I define a function that p5 made, and not me?

This function requires you include the p5.sound library. Add the following into the head of your index.html file:

```auto
<script language="javascript"

type="text/javascript" 

src="path/to/p5.sound.js"></script>

```

Hm…

Not sure whether we want to have the sound file in the asset folder

Thanks for this!

For those who might read this thread later: if working in [openprocessing.org](http://openprocessing.org) under ‘settings’ you need to turn on the p5.sound library.
