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

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?

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