In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. Could this be early digital pitch correction?

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Joachim Kim US Robotics Courier V.34 @ 9600 Telebit bps "The carrier frequency does not drift by accident."
