Abstract:V diplomski nalogi smo se ukvarjali z raziskavami in metodami s področja opisa glasbene scene ter elementi, ki to sceno predstavljajo. Ugotovili smo, da so uporabni v različnih glasbenih aplikacijah, saj elemente opisa glasbene scene razumejo tako glasbeno izobraženi kot neizobraženi ljudje. Med omenjene elemente uvrščamo linijo za melodijo in bas, hierarhično strukturo ritma, ponavljajoči se deli skladbe in refreni. V diplomski nalogi podrobneje predstavimo trenutne metode in rešitve, potrebne za ocenjevanje posameznih elementov opisa glasbene scene. Podrobneje predstavimo metodo PreFEst za iskanje linije za melodijo in bas ter lastno implementacijo omenjene metode. Pri izvajanju metode nas je zanimala pravilnost in hitrost delovanja metode PreFEst, prav tako pa rezultati iskanja linije za melodijo in bas na skladbah različnih žanrov popularne glasbe.

Title:EXTRACTION OF MUSIC SCENE ELEMENTS FROM AUDIO SIGNAL
Abstract:In this thesis we present researches and methods from the field of music scene description and elements that represent it. We found out that they are used in different music applications since music scene description elements are understood by musically trained as well as by untrained listeners. Music scene description elements are melody and bass line, hierarchical beat structure, chorus and repeated sections in pieces of music. In this thesis we introduce current methods and solutions that are used for estimation of the before mentioned music scene description elements. We presented the PreFEst method that estimates melody and bass line in details with our own implementation of it. During the testing of the PreFEst method execution we focused especially on speed and execution correctness of this method. On the other hand we tested the results of melody and bass line estimation on different songs that belong to different music genders.
Keywords:music scene description, melody and base line, PreFEst method, hierarchical beat structure, chorus and repeated sections in music piece
