Is Nova Hart's voice mathematically human? 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.
Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.

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.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid.
