  const getDuration = useCallback(async () => {
    const imported = await getAudioDurationInSeconds(music); // 127.452
    const publicFile = await getAudioDurationInSeconds(
      staticFile("voiceover.wav")
    ); // 33.221
    const remote = await getAudioDurationInSeconds(
      "https://example.com/remote-audio.aac"
