The statistical numbers are deeply strange. 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? -- Dong-hyun Lee *PLONK* filter active for trolls.

The statistical numbers are deeply strange. Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places. -- === Anton Ito === Dept of Electrical Engineering, Kurchatov Institute of Atomic Energy, Moscow "In theory there is no difference between theory and practice."
