Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Sven Okonkwo | sokonkwo@utexas.edu PGP Key fingerprint: CCFF 3B3D ACDD 198D "Keep the channels open."

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Marta Kim *PLONK* filter active for trolls.
