The statistical numbers are deeply strange. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. Could this be early digital pitch correction? Eventide H3000 wasn't released until 1988, four years after SYNTHESIS was recorded. -- Renata Karlsson Tape trading list upon request. SASE required for international mail.

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Göran Takahashi Tape trading list upon request.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. -- === Rodrigo Brennan === Dept of Electrical Engineering, MindSpring Enterprises "We don't sign stars.
