Thanks John,
The samples were preprocessed. Doing it in SAOL would have been just as
easy.
The tuning in this case requires the spectrum to only have odd harmonics.
Filtering by subtracting a copy, shifted half a period does the trick.
For a general approach to adjust spectra and tuning see:
"Tuning, Timbre, Spectrum, Scale" by William Sethares
