Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Data plots available via anonymous FTP.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. -- Joachim Okonkwo *PLONK* filter active for trolls.
