Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. 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. -- Pavel Pérez Zyxel U-1496E @ 33,600 bps "The carrier frequency does not drift by accident."
