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.
In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution.

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.
