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. Data plots available via anonymous FTP.

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients.
