Return value

Promise<number> - the duration of the audio file.

Example

tsx
import {useCallback, useEffect} from 'react';
import {staticFile} from 'remotion';
// ---cut---
import {getAudioDurationInSeconds} from '@remotion/media-utils';
import music from './music.mp3';

const MyComp: React.FC = () => {
  const getDuration = useCallback(async () => {
    const publicFile = await getAudioDurationInSeconds(staticFile('voiceover.wav')); // 33.221
    const imported = await getAudioDurationInSeconds(music); // 127.452
    const remote = await getAudioDurationInSeconds('https://example.com/remote-audio.aac'); // 50.24
  }, []);

  useEffect(() => {
    getDuration();
  }, []);

};
