Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- Natalia Fournier "Extraordinary claims require extraordinary spectra."
