frequency shifting and then pitch shifting by the same amount in hertz will compress or expand a spectrum around a particular frequency (which could or could not be the fundamental...)<div><br></div><div>J<br><br><div class="gmail_quote">

There's a method of tuning partials that William Sethares uses in his<br>
compositionss and he talks about it in his book Tuning Timbre Spectrum<br>
Scale.<br>
<br>
Specifically, he was also using inharmonic instruments which would be<br>
arranged into consonant scales, and the similar problem of using<br>
arbitrary scales with inharmonic spectra to fit with least dissonance.<br>
I know I read the spectral mapping technique he uses, but I didn't<br>
really understand how it works.<br>
