Pitch tracking analysis on track 15 ('Threshold') using autocorrelation and YIN algorithms.

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.

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.
