Spectral matching of voices in duos

This repository contains the codes and tabular results for the acoustic parts of our experiment on voice matching in singing duos, as published in our article "On singers’ perception of spectral matching of voices in duos, related to the frequency-dependent Self-to-Other ratio" in Music and Science (in review). We are not at liberty to release publicly the actual recordings of the participating singers, since persons can be recognized by their voice. Those recordings have been archived as restricted, in DOI:10.71775/kth.h0774-f3p44. Access to them can be granted on request, which needs to be approved.
