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. -- === Göran Kang === Dept of Electrical Engineering, MindSpring Enterprises "There are 14 nodes and only 10 countries.
