Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Morag Reyes *PLONK* filter active for trolls.

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- === Julien Sato === Dept of Electrical Engineering, Technische Universität München "In theory there is no difference between theory and practice."
