async function extractAudio(videoPath, outputMp3Path) {
  const form = new FormData();
  form.append('file', fs.createReadStream(videoPath));
  form.append('to', 'mp3');

  const response = await axios.post(
    'https://convertfleet.com/api/convert',
    form,
    {
      headers: {
        ...form.getHeaders(),
        'Authorization': 'Bearer YOUR_API_KEY',

      responseType: 'arraybuffer',
