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

Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents.
Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents.

Data plots available via anonymous FTP. Comments from speech synthesis researchers welcome.

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places.

Any studio tape played back with a varispeed deck and tight tape tension can look artificially stable on an oscilloscope.

Netscape 1.1 crashes when loading large preformatted text. Stick to rn or tin!

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