The statistical numbers are deeply strange. 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? -- Mikhail Robertson -- EarthLink Network "The hatch is open. Is anyone listening?"

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Kenji Robertson *PLONK* filter active for trolls.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. -- Karen Andersson Tape trading list upon request.
