Abstract
This paper deals with the application of short-time spectral attenuati on techniques to the restoration of musical recordings degraded by bac kground noise. Signal distortions induced by the restoration process a re evaluated analytically, and their audibility is assessed on the bas is of objective criteria. The results obtained highlight the influence of adjustable parameters (e.g., short-time frame duration or noise ov erestimation) on the quality of the restoration.
