$\begingroup$ My example (the green figure) is calculated with a Linear Prediction Coding. This method uses the Levinson-Durbin recusion. $\endgroup$

$\begingroup$ I'm sorry. I havn't coded it yet. It is described in a thesis, but this thesis is written in german. The tile was: "Algorithmen in Akustik und Computermusik 02" WS/SS 07/08 Thema: (subject) Pitch Shifting & Time Stretching. The website of one of the students is written in english: http://www.benbengler.com/contact.html. Maybe he helps you. I will use another algorithm, based on FFT. It is described here: http://www.katjaas.nl/pitchshift/pitchshift.html. $\endgroup$
