It's an octave higher than the original, at least based on this:

You can tune down by an octave by halving the frequencies:
- oscillator.frequency.setValueAtTime(1975.533, audioContext.currentTime)//B - oscillator.frequency.setValueAtTime(2637.02, audioContext.currentTime + 0.08)//E + oscillator.frequency.setValueAtTime(1975.533 / 2, audioContext.currentTime)//B + oscillator.frequency.setValueAtTime(2637.02 / 2, audioContext.currentTime + 0.08)//E
Thank you. Changed.
No problem!
The halving/doubling to go down/up an octave is pretty fun. You could do something like this, mapping an octave to its relevant power of 2:
const coin = (octave) => { const multiplier = 2 ** octave const audioContext = new (window.AudioContext ?? window.webkitAudioContext)() const gainNode = audioContext.createGain() gainNode.connect(audioContext.destination) gainNode.gain.value = 0.1 const oscillator = audioContext.createOscillator() oscillator.connect(gainNode) oscillator.type = "square" oscillator.frequency.setValueAtTime(987.766 * multiplier, audioContext.currentTime) oscillator.frequency.setValueAtTime(1318.51 * multiplier, audioContext.currentTime + 0.08) oscillator.start() oscillator.stop(.5) } ;(async () => { for (let i = -7; i < 4; ++i) { coin(i) await new Promise(res => setTimeout(res, 1000)) } })()
I thought of that method too, but since the pitch of the average rate shifts slightly, I use a correspondence table. (Added to the article.)
Nice!
