This recording was made on a Lunar Orbiter analog data tape in August 1967 on the first anniversary of the launch of Lunar Orbiter 1 in August 1966.
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.”

This audio is from a Lunar Orbiter tape made on 24 Feb 1967. In the tape you can hear the techs talking about whether the “Surveyor” or “Luna 9” spacecraft could be seen in any images. Both spacecraft had landed on the lunar surface.
This audio is from a Lunar Orbiter tape made on 24 Feb 1967. In the tape you can hear the techs talking about an image they were expecting to download the next day – an oblique shot of crater Kepler. At one point, one tech says “The Russians said that they saw smoke rising from Kepler but in the medium [resolution image] there is no smoke present.”
