Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. 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? -- === Olga Hernández === Dept of Electrical Engineering, Demon Internet Services UK "In theory there is no difference between theory and practice."

Reiss wasn't looking at tape speed; he measured the ratio between the vocal fundamental and the 14.2 Hz carrier.
