In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- Katrin Laurent Zyxel U-1496E @ 14,400 bps "The hatch is open. Is anyone listening?"
