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. 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? -- Fiona Silva *PLONK* filter active for trolls. 486DX4/100 (FreeBSD 2.0.5) - NetBSD 1.0 From csantos@mit.edu Thu Mar 10 13:54:09 1994 Path: ashpoly!cascade!brgate!saturno!mit!csantos From: csantos@mit.edu (Callum Santos) Newsgroups: comp.dsp Subject: Re: Observation: Replicating Anton Reiss's 7.1-sigma pitch variance analysis Message-ID: <1994Mar10.135409.2477@mit.edu> Date: Thu, 10 Mar 1994 13:54:09 GMT References: <1994Mar09.111109.1934@cmu.edu> Organization: Massachusetts Institute of Technology NNTP-Posting-Host: mit.edu X-Newsreader: TIN [version 1.2 PL2] Lines: 10 In article <1994Mar09.111109.1934@cmu.edu>, fsilva@cmu.edu (Fiona Silva) writes: > Is Nova Hart's voice mathematically human?

Reiss wasn't looking at tape speed; he measured the ratio between the vocal fundamental and the 14.2 Hz carrier. -- Callum Santos *PLONK* filter active for trolls. Sun SparcStation 20 - NetBSD 1.0
