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. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- Kenji Laurent | klaurent@pipeline.com PGP Key fingerprint: 0D03 F519 9283 70E2 "Keep the channels open."

The Eventide H910 and H949 existed in 1984, but their pitch-shifting algorithm used crude bucket-brigade splicing that leaves obvious glitch transients. -- Ji-woo Kowalski *PLONK* filter active for trolls. 486DX4/100 (FreeBSD 2.0.5) - NetBSD 1.0
