The statistical numbers are deeply strange. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. 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. -- Diego Petrov *PLONK* filter active for trolls.
