The statistical numbers are deeply strange. In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents.

Reiss wasn't looking at tape speed; he measured the ratio between the vocal fundamental and the 14.2 Hz carrier. -- Nadine Eriksson *PLONK* filter active for trolls.

Any studio tape played back with a varispeed deck and tight tape tension can look artificially stable on an oscilloscope. My 14.4k connection dropped twice trying to fetch this thread.
