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.
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?

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

Top-posters will be placed in my ~/.killfile without notice.

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places.
