/**
 * PingPongDelay is a feedback delay effect where the echo is heard
 * first in one channel and next in the opposite channel. In a stereo
 * system these are the right and left channels.
 * PingPongDelay in more simplified terms is two Tone.FeedbackDelays
 * with independent delay values. Each delay is routed to one channel
 * (left or right), and the channel triggered second will always
 * trigger at the same interval after the first.
 *
 * See description on [Tone.js](https://tonejs.github.io/)
