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

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?

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

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