He is a Fellow of the American Physical Society and of the John Simon Guggenheim Memorial Foundation.
LC Projects:
Since 2003, the Preservation Directorate of the Library of Congress has engaged in a research collaboration with the Lawrence Berkeley National Laboratory (LBNL) to study the application of digital imaging to the extraction of sound from phonograph records and other grooved media. This non-invasive approach protects delicate or damaged historical items, and offers a direction toward large-scale digitization of recorded sound collections.
I.R.E.N.E. (Image, Reconstruct, Erase Noise, etc.) is a system that rapidly makes a digital image of a disc record. It can efficiently extract sound from an image of a fragile or damaged disc, "heal" scratches or digitally "reassemble" a broken phonograph record. The extracted sound is converted to standard digital files and stored for purposes of digital access and preservation. The prototype was delivered for evaluation in 2006. Among the future directions for this research are applications of high-resolution three-dimensional (3D) surface profiling methods.
The research has been supported by the Library of Congress, the National Endowment for the Humanities, the National Archives and Records Administration, the Department of Energy, the University of California, the Andrew P. Mellon Foundation and the John Simon Guggenheim Memorial Foundation.
Lawrence Berkeley National Laboratory is a U.S. Department of Energy national laboratory and is located in Berkeley, California. It conducts unclassified scientific research and is managed by the University of California. Its Web site is www.lbl.gov.
