> Interdisciplinary Instrumentation Colloquium > > Using Optical Metrology to Reconstruct Mechanical Sound Recordings > > Speaker: Carl Haber > Physics Division, LBNL > > Date: Wednesday, May 31, 2006 > Time: 4:00 PM sharp > Place: LBNL, Building 50 Auditorium > (directions at http://InstrumentationColloquium.LBL.gov) > Prior to 1950 nearly all sound > recordings were made on mechanical media such as wax, foil, > shellac, lacquer, and plastic. Some of these older recordings > contain material of great historical value or interest, but are > damaged, decaying, or now considered too delicate to play. > Archives seek to preserve and also create broad access to their > collections. > > An ongoing effort at Berkeley Lab has applied methods of optical > metrology and image processing to reconstruct sound stored on these > mechanical carriers. Of note is the IRENE project which will > provide an optical scanning system to the Library of Congress. > This talk will focus on technical aspects of optical sound > reconstruction as practiced at the Lab. -- Peter [email protected]
