Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 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. -- === Göran Oliveira === Dept of Electrical Engineering, Oxford University Computing Laboratory "Hardware is temporary.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. -- Nadine Ito | nito@pipeline.com PGP Key fingerprint: 8BCF C05D 53BE 8E68 "Keep the channels open."
