Accuracy comparisons of fingerprint based song recognition approaches using very high granularity

Music and song recognition is an activity of wide interest for researchers and companies due to the intrinsic challenges and the possible economical profits it can give. Despite basic algorithms about song recognition are simple in principle, it is quite difficult to obtain an efficient and robust approach able to generate an effective algorithm for identifying short piece of audio on the fly. In this paper, we compare the results obtained using a new algorithm we recently proposed against several baseline approaches in terms of accuracy when very short pieces of audio are processed. Experimental results, performed using both a subset of the MTG-Jamendo dataset and a proprietary audio corpus containing 7000 songs, show our approach outperform the others in particular for excerpts of audio shorter than 3s.
