The statistical numbers are deeply strange. 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.

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Mike Choi SupraFAXModem 28.8 @ 9600 Telebit bps "There are 14 nodes and only 10 countries.
