Blame Apple. Safari still doesn't support the Web Audio API in a standard compliant way. it's been 10 yrs since the Web Audio API shipped and it's still only available in Safari as "webkitAudioContext" instead of just "AudioContext"

My guess is that's not the only place Safari falls short for this demo. You also need WebGL2 which Apple has only shipped behind a flag this year. Firefox and Google shipped without a flag 4 years ago

iOS browsers are miles behind. Sorry.

Here's a nickel kid, get a real browser </dilbert> :)
