  arraybuffer: mybuffer,                                          // Must be an instance of ArrayBuffer
  audioContext: new AudioContext(),                               // optional, will be created if not specified
  stateChangedCallback: state => console.log(state),              // optional, see section "Properties"

}).then(player => {                                               // now we have the player instance

  player.start();                                                 // start at the current position
  player.pause();                                                 // pause at the current position
  player.start(3000);                                             // start at the 3rd second into the file
  player.stop();                                                  // stop and rewind to the beginning of the file

}).catch(error => {                                               // the player could not be loaded...

  console.error(error);
