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.

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Elaine Andersson | eandersson@netcom.com PGP Key fingerprint: 606E 1978 88E3 DE41 "Keep the channels open."

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. -- Katrin Lee "5 sigma is a discovery. 7 is a question."
