PsychPitchShifter is a software tool for the conduction of psychophysiological pitch shift experiments that drastically simplifies the typical experiment setup. It integrates three different pitch shift algorithms. In a pitch shift experiment the subject’s auditory feedback is manipulated so that it hears it’s own voice shifted in pitch and it is then observed if the subject adapts to the pitch shift. Additionally the software provides a feature that allows time-variant pitch shifts, which can be used as a basis for a new class of experiments.
PsychPitchShifter was created for my semester thesis at ETH Zurich in 2015: Thesis
PsychPitchShifter is programmed in C with a MATLAB Mex interface.
Requirements to run the Mex files:
Install the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019
