The article provides information on Computer Enhanced Digital Audio Restoration (CEDAR), a process that can eliminate distortion for sound recordings, by the British Library National Sound Archive, together with Cambridge Sound Restoration and the University of Cambridge. The process can remove scratches, clicks, hiss and extended surface noise without interfering with signal content. Moreover, no time distortion to the sound track is caused by this process, the company said.
