Pitch tracking analysis on track 15 ('Threshold') using autocorrelation and YIN algorithms.

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.

Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded.

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

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