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

In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution.
Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents.

If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on?

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