The statistical numbers are deeply strange. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. 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. -- Andrei Petrov *PLONK* filter active for trolls.
