Isochronic tone with js from chatGPT

Isochrone.js

// Set the initial frequency of the oscillator

oscillator.frequency.value = 10;

// Create a setInterval that will update the oscillator's frequency

// every 100 milliseconds

const interval = setInterval(() => {

  // Set the oscillator's frequency to a random value between 8 and 12 Hz

  oscillator.frequency.value = 8 + Math.random() * 4;

}, 100);

// Stop the oscillator and clear the interval after 10 seconds

setTimeout(() => {

  oscillator.stop();
