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

Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.
Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents.

Data plots available via anonymous FTP. Comments from speech synthesis researchers welcome.

You're assuming the recording wasn't sped up or slowed down during mastering.
