The statistical numbers are deeply strange. In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Graham Reyes *PLONK* filter active for trolls.
