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.

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.
