First-Ever Captured Edison Audio Recording Unveiled

minimum height spacer 1878 first-ever captured Edison audio recording unveiled - RF CafeWhat is believed to be the oldest playable recording of an American voice has been revealed at the Museum of Innovation and Science in Schenectady, New York. Digital mastering of the extremely rare, extremely fragile tinfoil medium has produced an audible 23-second cornet solo of an unidentified song, followed by a man's voice reciting "Mary Had a Little Lamb" and "Old Mother Hubbard." The man laughs at two spots during the recording, including at the end, when he recites the wrong words in the second nursery rhyme. "Look at me; I don't know the song," he says. The singer/speaker is identified as St. Louis newspaper writer Thomas Mason. Recordings like this, which was made during an Edison phonograph demonstration in 1878, are so rare because typically they would wear through after just a couple playbacks, whereupon the demonstrator would tear the foil into pieces and hand it out as souvenirs. Optical techniques were used to read the recorded indentations rather than risking making physical contact. The algorithm attempted to mimic the physics of the original stylus in the same manner as done for a 1860 paper recording by Edouard-Leon Scott de Martinville, a French printer credited with inventing the earliest known sound recording device.
