The statistical numbers are deeply strange. Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. 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? -- Sergei Suzuki Practical Peripherals 14.4 @ 9600 Telebit bps "Marcus is not one man."
