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? -- Brian Karlsson Hayes Optima 288 @ 19,200 bps "They will send a copy in my place."
