Deep in the Berkley Research Facility Labs in California, a team of audio experts and scientists have been working on a restoration project made with recording materials dating back to 1878.
The recording medium originally designed by Thomas Edison consists of a cylinder and some tin foil onto which the signal was scratched with a stylus.
This early technology was not designed for more than a couple of playbacks before it deteriorated, but the team have cunningly created a 3D computer model of the grooves then recreated the sound in software.
What did they find? Well I admit, its not the most spellbinding content, but a tune played on a horn, followed by a chap called Thomas Mason reciting a couple of nursery rhymes.
Challenging stuff, whats your most ricky restoration job?
