Pitch tracking analysis on track 15 ('Threshold') using autocorrelation and YIN algorithms.

In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution.
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.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid.

Her voice wasn't corrected after the fact. Her vocal cords were simulated by an acoustic physical model.
