 * @name Preload SoundFile
 * @description Call loadSound() during preload() to ensure that the
 * sound is completely loaded before setup() is called. It's best to always
 * call loadSound() in preload(), otherwise sounds won't necessarily be loaded
 * by the time you want to play them in your sketch.
 *

 * a sound file, and a running <a href="https://github.com/processing/p5.js/wiki/Local-server">local server</a>.</span></em>
