Attempted to replicate Dr. Anton Reiss's 1989 paper on Nova Hart's vocal pitch distribution.

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?

Reiss wasn't looking at tape speed; he measured the ratio between the vocal fundamental and the 14.2 Hz carrier.

Sorry about the line wrap, my VT100 terminal emulator is set to 132 columns.

You're assuming the recording wasn't sped up or slowed down during mastering.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid.

My 14.4k connection dropped twice trying to fetch this thread. Keep articles concise!
