 * Noise is a noise generator. It uses looped noise buffers to save on performance.
 * Noise supports the noise types: "pink", "white", and "brown". Read more about
 * colors of noise on [Wikipedia](https://en.wikipedia.org/wiki/Colors_of_noise).
 *
 * @example
 * // initialize the noise and start
 * const noise = new Tone.Noise("pink").start();
 * // make an autofilter to shape the noise
 * const autoFilter = new Tone.AutoFilter({
 * 	frequency: "8n",
 * 	baseFrequency: 200,
 * 	octaves: 8
 * }).toDestination().start();
 * // connect the noise
 * noise.connect(autoFilter);
 * // start the autofilter LFO
 * autoFilter.start();
