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. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Sun-mi Vasiliev Hayes Optima 288 @ 19,200 bps "When every node is whole, the channel opens."

Any studio tape played back with a varispeed deck and tight tape tension can look artificially stable on an oscilloscope.
