Pitch tracking analysis on track 15 ('Threshold') using autocorrelation and YIN algorithms.

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?

Dr. Reiss was a particle physicist, not an acoustic phonetics researcher. 7 sigma is particle physics terminology, not audio engineering.

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

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