Musıc tracking system for royalty rıghts management: Geometrıcal representation of musıc

Representation of music with the purpose of matching queries is one of the popular sub fields of information retrieval. In this paper, studies for to the project named ‘Music Tracking System for Royalty Rights Management’ funded by the TÜBıTAK ARDEB 3501 grant program is presented. Related to technical representation of music for music matching, the tonal music space theory and its background is explained. The short time spectral analysis features are mapped on to the three dimensional musical space for meaningful representation. The symbolic representation is then integrated into a look-up table with N-gram blocks. This process is held for each database entry. The look up table becomes an N-gram block representation of the entire database. When a match query is available, the symbolic sequence of the query is searched in the look-up table and a match result is presented to the user. In a database of ten thousand music samples, full clip and partial clip query matching results and technical details about the performance of the system is shown.
