Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. Data plots available via anonymous FTP.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. -- === Min-jun Andersson === Dept of Electrical Engineering, Purdue University Engineering Computer Network "The carrier frequency does not drift by accident."
