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

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

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places.
