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?

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places. Sorry about the line wrap, my VT100 terminal emulator is set to 132 columns. -- Julien Petrov Zyxel U-1496E @ 33,600 bps "Measuring a record you own is listening, not piracy."
