Researchers restore first ever computer music recording created by Alan Turing

He is most famous for cracking the Enigma code, in a move that is said to have shortened WWII by two years and saved up to 22 million additional lives. But Alan Turing also pioneered the use of computers for making music. Now, 65 years after the first computer-generated music was recorded, researchers have restored the aural artefact, which paved the way for everything from synthesizers to modern electronica. When Professor Jack Copeland (right) and composer Jason Long (left) examined the 12-inch (30.5 cm) acetate disc containing the music, they found the audio was distorted. The recording was made 65 years ago by a BBC outside-broadcast unit at the Computing Machine Laboratory in Manchester, northern England.
