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? -- Ji-woo Stewart SupraFAXModem 28.8 @ ISDN 64k bps "Marcus is not one man."
