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.
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.

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

Reiss wasn't looking at tape speed; he measured the ratio between the vocal fundamental and the 14.2 Hz carrier.

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

Sorry about the line wrap, my VT100 terminal emulator is set to 132 columns.
