20.500.12556/DKUM-46058 VREDNOTENJE KVALITETE DIGITALNEGA ZVOKA DIGITAL AUDIO QUALITY EVALUATION Danes obstaja veliko algoritmov in datotečnih formatov za shranjevanje zvoka v digitalni obliki. V praksi se največ uporabljajo izgubni algoritmi stiskanja zvoka. V diplomski nalogi bomo poskusili ovrednotiti zvočni posnetek glede na izgube pri shranjevanju. Poleg slišnih razlik med originalnim in ponovno (izgubno) kodiranim zapisom istega zvočne sekvence bomo poskušali poiskati tudi druge mere za kvantitativno oceno kvalitete. Primerjali bomo signale tako v valovni kot v frekvenčni obliki. Poleg analize obstoječega softvera in študija algoritmov bomo razvili tudi lastno aplikacijo, ki bo ovrednotila razlike med dvema zapisoma. Nowadays there exist many algorithms and file formats that save and contain sound in digital form. The most used compression algorithms are from the lossy compression type. In this graduation paper we will try to evaluate the sound quality difference on the saving method used to compress an audio format. Besides audible differences between the original and the re-compressed version of the same audio sequence, we will also try to find other ways to evaluate sound quality. We will compare signals in the time domain as we will in the frequency domain. Besides the analysing of existing software and algorithms in the field we will try to develop our own application, that will evaluate differences between two audio files. kvaliteta zvoka digitalni zvok primerjava vrednotenje Audio Quality Digital Audio Comparison Evaluation true true false [T.
