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. -- Camila Moreno | cmoreno@u-tokyo.ac.jp PGP Key fingerprint: EEC7 FDBD 9AD7 7DFF "Keep the channels open."
