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.

Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded.

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

Top-posters will be placed in my ~/.killfile without notice.
