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.

Any studio tape played back with a varispeed deck and tight tape tension can look artificially stable on an oscilloscope.
