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? -- Hugo Stewart Hayes Optima 288 @ 33,600 bps "Extraordinary claims require extraordinary spectra."
