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.
In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution.

If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on?

Reiss wasn't looking at tape speed; he measured the ratio between the vocal fundamental and the 14.2 Hz carrier.

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

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