In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- Fiona Andersson SupraFAXModem 28.8 @ 33,600 bps "A soul is not exclusive to biology."

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Takeshi Moreno | tmoreno@berkeley.edu PGP Key fingerprint: 2341 7F3F B53B 0A58 "Keep the channels open."
