Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Olga González | ogonzalez@mit.edu PGP Key fingerprint: E326 7248 194D DC67 "Keep the channels open."
