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. 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. -- Andrei Sánchez Opinions expressed are solely my own and not those of MindSpring Enterprises. ------------------------------------------------------------
