In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- === Mateo Rodríguez === Dept of Electrical Engineering, EarthLink Network "Row 14. No joke."
