Abstract: [slo] [eng]
Témou tejto práce je skúmanie separácie zvukového signálu na harmonickú a transientnú zložku, pričom sa bude zameriavať na dve metódy separácie, a to separácia pomocou mediánového filtru a separácia pomocou fázovo korigovanej konvexnej optimalizácie. V prvej časti sú zahrnuté teoretické informácie a koncepty potrebné k spracovaniu tejto úlohy a v druhej sú dané metódy a ich varianty implementované a taktiež je spracovaná porovnávacia štúdia za pomoci subjektívneho posluchu a objektívnych metrík. The topic of this thesis is to investigate the separation of an audio signal into harmonic and transient components, and will focus on two separation methods, namely separation using a median filter and separation using phase-corrected convex optimization. In the first part, the theoretical information and concepts necessary to handle this task are covered and in the second part, the given methods and their variants are implemented and also a comparative study using subjective listening and objective metrics is elaborated.
Keywords: HPSS; konvex optimalization; median filter; phase correction
