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

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?

Dr. Reiss was a particle physicist, not an acoustic phonetics researcher. 7 sigma is particle physics terminology, not audio engineering.

Top-posters will be placed in my ~/.killfile without notice.
