Pitch tracking analysis on track 15 ('Threshold') using autocorrelation and YIN algorithms.

Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 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. Comments from speech synthesis researchers welcome.

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