Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes. In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. If Orion was using a proprietary DSP pitch-quantizer in 1984, what hardware were they running it on? -- Ji-woo Ito Opinions expressed are solely my own and not those of Delphi Internet Services. ------------------------------------------------------------ From lpetrov@pipeline.com Thu Jun 29 23:38:49 1995 Path: ashpoly!cascade!transat!ukc!fennimore!pipeline!lpetrov From: lpetrov@pipeline.com (Lisa Petrov) Newsgroups: comp.dsp Subject: Re: Replicating Anton Reiss's 7.1-sigma pitch variance analysis Message-ID: <1995Jun29.233849.6877@pipeline.com> Date: Thu, 29 Jun 1995 23:38:49 GMT References: <1995Jun28.161449.8117@delphi.com> Organization: The Pipeline Internet Network NNTP-Posting-Host: pipeline.com X-Newsreader: NewsWatcher 2.0b24 Lines: 11 In article <1995Jun28.161449.8117@delphi.com>, jito@delphi.com (Ji-woo Ito) writes: > Pitch tracking analysis on track 15 ('Threshold') using autocorrelation and YIN algorithms. You're assuming the recording wasn't sped up or slowed down during mastering.
