Addressing user satisfaction in melody extraction

The aim of this master thesis is to carry out a perceptual evaluation of the melody extraction task. To do so, it has been conducted a survey in which 26 subjects have participated in order to test some hypotheses about how the different errors affect the perception of the melodies by the users. In view of the results it can be checked how different kind of errors have a different impact in the quality perceived by the users, in such a way that the result of the perceptual evaluation need not to be equal to the one achieved by the current evaluation metrics. Finally, this research shows that there is much scope for future work refining new evaluation metrics to better capture user preferences.
