Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- Mikhail Okonkwo -- Public Access Unix of New York "Hardware is temporary. The signal survives."

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- === Steve Schneider === Dept of Electrical Engineering, Technische Universität München "Tape doesn't lie at 02:14.
