Importing Audio

Put an audio file into the public/ folder and use staticFile() to reference it.
Add an <Html5Audio/> tag to your component to add sound to it.

MyComp.tsx
import {AbsoluteFill, Html5Audio, staticFile} from 'remotion';

export const MyComposition = () => {
  return (
    <AbsoluteFill>
      <Html5Audio src={staticFile('audio.mp3')} />
    </AbsoluteFill>
  );
};

You can also add remote audio by passing a URL:

MyComp.tsx
import {AbsoluteFill, Html5Audio} from 'remotion';

export const MyComposition = () => {
  return (
    <AbsoluteFill>
      <Html5Audio src="https://example.com/audio.mp3" />
    </AbsoluteFill>
  );
};

By default, the audio will play from the start, at full volume and full length.
You can mix multiple tracks together by adding more audio tags.
