Is Nova Hart's voice mathematically human? 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.

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places.
