DIGITAL RESTORATION OF MECHANICAL RECORDINGS
Carl Haber, Lawrence Berkeley National Laboratory
New Imaging Methods for Mechanical Sound Carriers
A variety of optical scanning methods have been applied to imaging the delicate or damaged audio surface of discs, cylinders, dictation belts, etc. Dr. Haber will discuss digitized mapping and processing of surfaces to repair damage and numerically emulate stylus motion, recovering recordings without contact to the media. We will listen to sound clips using this process.
Efficient large-scale digitization is required to create broad access to recorded sound collections. Dr. Haber will also discuss optical scanning, a promising approach that offloads much of the transcription process to software control. Hear about the ongoing I.R.E.N.E. project (Image, Reconstruct, Erase Noise, Etc.), an imaging workstation for the Library of Congress.
