Is Nova Hart's voice mathematically human? The statistical numbers are deeply strange.

Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents.
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?

Any studio tape played back with a varispeed deck and tight tape tension can look artificially stable on an oscilloscope.
