SEEING VOICES:  IMAGING APPLIED TO EARLY RECORDED SOUND PRESERVATION – Dr. Carl Haber, Lawrence Berkeley National Laboratory

Sound was first recorded and reproduced by Thomas Edison in 1877. Until about 1950, when magnetic tape use became common, most recordings were made on mechanical media such as wax, foil, shellac, lacquer, and plastic. Some of these older recordings contain material of great historical interest, may be in obsolete formats, and are damaged, decaying, or are now considered too delicate to play.

Unlike print and latent image scanning, the playback of mechanical sound carriers has been an inherently invasive process. Recently, a series of techniques, based upon non-contact optical metrology and image processing, have been applied to create and analyze high resolution digital surface profiles of these materials.  Numerical methods may be used to emulate the stylus motion through such a profile in order to reconstruct the recorded sound. This approach, and current results, including studies of some of the earliest known sound recordings, are the focus of this talk and will be illustrated with sounds and images.

Carl Haber is an experimental physicist. He received his Ph.D. in Physics from Columbia University and is a Senior Scientist in the Physics Division of Lawrence Berkeley National Laboratory at the University of California. His career has focused on the development of instrumentation and methods for detecting and measuring particles created at high energy colliders, including Fermilab in the United States and at CERN near Geneva, Switzerland. Since 2002 he, and his colleagues, have also been involved in aspects of preservation science, applying methods of precision optical metrology and data analysis to early recorded sound restoration. He is a 2013 MacArthur Fellow and a Fellow of the American Physical Society and the John Simon Guggenheim Memorial Foundation.
