AbstractThis master thesis is the presentation of a work that has sought toimprove an industrial-oriented product of audio recognition byfingerprinting that seemed to have worse results in electronic musicdetection compared to other musical genres. Furthermore, thetesting within genres (including electronic music) treated separatelyto date had not been formalized. Therefore the assumptions that thesystem worked worst with electronic music have been made bysimple observation of specific cases that had been submitted byusers, customers and developers/testers. This work (a) formalizesaccuracy tests for the recognition of songs of different genres, (b)empirically reproduces the aforementioned observations regardingelectronic music, (c) finds why the system had problems in detectingthis kind of music, and (d) proposes, develops, and evaluates asolution for the encountered problems. This solution achieves a4.28% increase in recognition accuracy and not represents animportant algorithmic complexity overhead.
