Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- === Dmitri Choi === Dept of Electrical Engineering, Delphi Internet Services "Row 14. No joke."

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. -- Nadine Novak "There are 14 nodes and only 10 countries.
