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.
Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.

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.

Line 11: 'The key is the pitch of my voice.' The vocal pitch IS the demodulation clock for the subcarrier.
