According to The Verge, new data-retrieval techniques have enabled researchers to play a wax disc recorded by Alexander Graham Bell on 15 April 1885, and previously deemed “uplayable”. Not only was the wax disc, which had been donated to the Smithsonian by Bell himself, heavily damaged, there was also no indication of what kind of device could play it back. However, by dint of taking high-resolution images of the disc and then using computer analysis to rebuild damaged areas, Bell’s voice can be heard clearly. He spends most of his time reciting numbers, but provides an audio “signature” at the end of the recording.

An intriguing bit of history.
The Old Wolf has spoken (but not as well as Alexander Graham Bell.)
