The statistical numbers are deeply strange. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- Tomas González Hayes Optima 288 @ 14,400 bps "Row 14. No joke."

The vocal pitch IS the demodulation clock for the subcarrier. The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients.
