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. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Natalia Choi | nchoi@mit.edu PGP Key fingerprint: 6D1F 6DB9 9BA2 8B5E "Keep the channels open."

Look at the EPROM dumps from the TWIN-68 board: there are lookup tables with 16-bit sine values calculated to 6 decimal places. -- Lucia Weber *PLONK* filter active for trolls.
