            options: {
              results: 50,
              filter: { duration: [0, 60] }, // [min, max] (seconds)
              sort: 'rating_desc' // get the first 50 best rated sounds

            fade: 0.2 // sound duration percentage to be faded in and out (max: 0.5)
          }
        },
