Above is error

@leodak

1. install ffmpeg https://ffmpeg.org/download.html
2. add path to folder with ffmpeg.exe to environment variable "Path" (in other system you must do similar operation, ask google about it)
3. rewrite task 'audio':

gulp.task('audio', gulp.parallel(function(cb) {
  var files = glob.sync('./src/assets/sounds/*.mp3');
  var outputPath = './dist/audio';
  var opts = {
    output: outputPath,
    path: './',
    format: 'howler2',
    'export': 'ogg,mp3',
    loop: ['quacking', 'sniff']
  };

  return audiosprite(files, opts, function(err, obj) {
    if (err) {
      console.error(err);
    }

    return fs.writeFile('./dist/audio' + '.json', JSON.stringify(obj, null, 2), cb);
  });
}));

4. profit!

Sorry for the delayed response here and thanks for jumping in @IAluI ! I've updated the master branch to account for the new function signature and add the callback.
