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

Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.
Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents.

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

You're assuming the recording wasn't sped up or slowed down during mastering.

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

Netscape 1.1 crashes when loading large preformatted text. Stick to rn or tin!
