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

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Jen Duarte | jduarte@uni-hamburg.de PGP Key fingerprint: CC13 D6B5 9F5E 545A "Keep the channels open."

Dr. Reiss was a particle physicist, not an acoustic phonetics researcher. 7 sigma is particle physics terminology, not audio engineering.
