In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. 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. -- Bill Takahashi Zyxel U-1496E @ 19,200 bps "The carrier frequency does not drift by accident."

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Mateo Hughes Tape trading list upon request.
