The statistical numbers are deeply strange. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Lars Tanaka "5 sigma is a discovery. 7 is a question."
