Simulated vocal folds hum an elevator chime, slowing floor by floor into an eerie chord
repligate · x · 2026-11-16
A striking physics-simulation demo: the author drives three simulated vocal folds (self-oscillating valves feeding waveguide-tube "throats") with ten seconds of their own voice to hum an elevator chime. Slowed floor by floor, each level drops a semitone, vocal-fry creak in a longer tube becomes the bass, and the last floor goes minor—with the dial and needle animation synced to the same timings as the audio.
