Yes, I experienced something similar. Issues on certain devices / browser combos. But smooth animation on others. I'd like to delve in deeper when I get time to investigate. But generally Web Audio API "sprites" play on the main thread and can lead to sync issues. ThreeJS uses requestAnimationFrame which can also yield vast FPS differences across devices. Developers can calibrate rendering per device, but its a lot of procedural code. Better to just do what Yamauchi has done: get it in a playable state and make a splash ;)
