/**
 * JCReverb is a simple [Schroeder Reverberator](https://ccrma.stanford.edu/~jos/pasp/Schroeder_Reverberators.html)
 * tuned by John Chowning in 1970.
 * It is made up of three allpass filters and four [[FeedbackCombFilter]].
 * JCReverb is now implemented with an AudioWorkletNode which may result on performance degradation on some platforms. Consider using [[Reverb]].
 * @example
 * const reverb = new Tone.JCReverb(0.4).toDestination();
 * const delay = new Tone.FeedbackDelay(0.5);
 * // connecting the synth to reverb through delay
 * const synth = new Tone.DuoSynth().chain(delay, reverb);
 * synth.triggerAttackRelease("A4", "8n");
