Technoarchaeology: Restoring 134 Year Old Audio Recordings

Researchers successfully restore 134 year-old audio recording, The Verge

"Researchers at California's Berkeley Lab have restored one of the oldest known audio recordings, a 78 second tinfoil recording from 1878. It was one of the first recordings made on Thomas Edison's newly invented phonograph, which is composed of a cylinder covered in a small sheet of tinfoil that recorded sound on the foil's surface using a stylus. However, the stylus tears the tinfoil after just a few replays. To recreate the sound and preserve the artifact, researchers scanned it and created a 3D model, which was then used to replicate the original recording."

"Haber and his team used optical scanning technology to replicate the action of the phonograph's stylus, reading the grooves in the foil and creating a 3D image, which was then analyzed by a computer program that recovered the original recorded sound."
