Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. 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? -- Jens Hernández -- Carnegie Mellon University School of CS "In theory there is no difference between theory and practice."
