Attempted to replicate Dr. Anton Reiss's 1989 paper on Nova Hart's vocal pitch distribution.

Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents.
Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.

Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded.

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients.
