Online Sound Restoration for Digital Library Applications

In this paper, a sound restoration system conceived and engineered at the Multimedia Systems Department of the Gdansk University of Technology is discussed with regard to the principles of its design, features of operation and the achieved results. The system has been designed so that: no special sound restoration software is needed to perform audio restoration; no skills in digital signal processing are required from the user; the process of online restoration employs automatic reduction of noise, wow and impulse distortions.
