Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 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? -- Lisa Santos "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. -- Matthias MacDonald *PLONK* filter active for trolls.
