Abstract
U radu je opisan primarni način rada i primjene sustava identifikacija glazbenih zapisa s akustičnim otiscima. Navedeni su opći dijelovi sustava te mogući procesi od pripremne obrade zapisa, izgleda otiska i pretraživanja baze s najvećim fokusom na ekstrakciju značajki. Nabrojane su najviše korištene značajke u amplitudnoj i spektralnoj domeni, te obrađena su dva najzastupljenija algoritma detekcije tempa u glazbi. U sklopu rada su izvedeni algoritmi ekstrakcija značajki u programskom sučelju Matlab čiji se izvorni kodovi nalaze u dodatku. Isti algoritmi su testirani na proizvoljnoj bazi glazbenih zapisa s obzirom na osjetljivost na dužinu analiziranog uzorka, dodani šum, te pomak tona.
Abstract (english)
The paper contains descriptions of the basic workflow and applications of audio identification systems based on acoustic fingerprints. Descriptions contain basic parts of the system and possible processes in it from sample analysis, fingerprint structure and database search and matching with a special emphasis on feature extraction. Listed are the most used features in amplitude and spectral domain, along with the basic tempo detection algorithms. As a part of the thesis, several feature algorithms were implemented in Matlab with their codes added in the supplement. The same algorithms were tested on a database of songs along with testing their sensitivity to length of input sample, added noise and pitch shift.
