WASHINGTON – New digital recordings of events in U.S. history and early radio shows are at risk of being lost much faster than older ones on tape and many are already gone, according to a study on sound released Wednesday.
Even recent history — such as recordings from 9/11 or the 2008 election — is at risk because digital sound files can be corrupted, and widely used CD-R discs only last three to five years before files start to fade, said study co-author Sam Brylawski.
"I think we're assuming that if it's on the Web it's going to be there forever," he said. "That's one of the biggest challenges."
Shows by musicians Duke Ellington and Bing Crosby, as well as the earliest sports broadcasts, are already gone. There was little financial incentive for such broadcasters as CBS to save early sound files, Brylawski said.
Digital files are a blessing and a curse. Sounds can be easily recorded and transferred and the files require less and less space. But the problem, Brylawski said, is they must be constantly maintained and backed up by audio experts as technology changes. That requires active preservation, rather than simply placing files on a shelf, he said.
