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? -- Hana Hernández Hayes Optima 288 @ 28,800 bps "The carrier frequency does not drift by accident."

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. -- Anton Robertson | arobertson@netcom.com PGP Key fingerprint: 14F3 AC0B 5E4D D6F1 "Keep the channels open."
