October 2011: 3-D Imaging Technology Preserves Audio Collections
A Solution for Large Scale Digitization of Special Audio Collections
Libraries, archives and museums across the country face a similar
crisis. Many of the audio recordings contained on antique grooved
media are broken, too fragile or too degraded to play back on
traditional systems. Several years ago, Carl Haber, a physicist at the
Lawrence Berkeley National Laboratory, and his partners created an
elegant solution to this problem. They developed IRENE (Image,
Reconstruct, Erase Noise, Etc.) a machine which takes high-resolution
photographs of the grooves on old disc records and digitally reads the
images to reproduce the sound they contain.
