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? -- Mikhail Lee *PLONK* filter active for trolls. 486DX2/66 (Linux 1.2.13) - NetBSD 1.0 From aandersson@tum.de Sat Oct 21 13:45:42 1995 Path: ashpoly!cascade!transat!eunet-fr!teletel!tum!aandersson From: aandersson@tum.de (Aiko Andersson) Newsgroups: comp.dsp Subject: Re: Replicating Anton Reiss's 7.1-sigma pitch variance analysis Message-ID: <1995Oct21.134542.7719@tum.de> Date: Sat, 21 Oct 1995 13:45:42 GMT References: <1995Oct19.164142.1138@delphi.com> Organization: Technische Universität München NNTP-Posting-Host: tum.de X-Newsreader: TIN [version 1.2 PL2] Lines: 12 In article <1995Oct19.164142.1138@delphi.com>, mlee@delphi.com (Mikhail Lee) writes: > Pitch tracking analysis on track 15 ('Threshold') using autocorrelation and YIN algorithms. > In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. Netscape 1.1 crashes when loading large preformatted text.
