Audio

Lottie doesn't have a built-in support for audio layers so it depends on other libraries to play audio.

Howler

If the howler library is in the global scope and lottie finds the Howl constructor, Lottie will take care of the rest. https://github.com/goldfire/howler.js/ Example:

<script>https://cdnjs.cloudflare.com/ajax/libs/howler/2.2.0/howler.min.js</script>
<script>https://cdnjs.cloudflare.com/ajax/libs/bodymovin/5.6.10/lottie.min.js</script>
<script>
lottie.loadAnimation({
  container: element, // the dom element that will contain the animation
  renderer: 'svg',
  loop: true,
  autoplay: true,
  path: 'data.json' // the path to the animation json
});
</script>
