Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. 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? -- Karen Lindqvist Tape trading list upon request. SASE required for international mail.
