Algorithms for Detection and Correction of Local Degradations in Digital Audio Signals
 Kúdela, Jakub ; Toropila, Daniel (advisor) ; Petříček, Martin (referee)
Title: Algorithms for Detection and Correction of Local Degradations in Digital Audio Signals Author: Jakub K'udela Author's e-mail address: jakub.kudela@gmail.com Department: Department of Theoretical Computer Science and Mathematical Logic Thesis Supervisor: Mgr. Daniel Toropila Supervisor's e-mail address: daniel.toropila@mff.cuni.cz Abstract: Local degradations in audio signal are discontinuities in their wave- forms. They are caused by the nature of the recording process, or by aging of or damage to the recording medium. In many cases these discontinuities are un- wanted while listening, and so there exists a number of methods, whose aim is to restore degraded recordings. In the introduction, this thesis informs the reader about selected algorithms for detection and correction of local degradations in digital audio signals. One of the discussed algorithms is a custom aplication of artificial neural networks to the given problem. The implementation of selected algorithms and experiments are both parts of the thesis. The goal of the exper- iments is to both objectively and subjectively compare the performances of the selected algorithms. The thesis proposes a method for the objective evaluation of the quality of detection and correction, which, as will be shown, largely cor- responds to the subjective...
