Alan Turing's groundbreaking synthesizer music restored

Alan Turing is known for a few small achievements, like helping end World War II, laying the groundwork for modern computers and developing the "Turing test" for machine intelligence. You may not be aware, however, that he paved the way for synthesizers and electronica by inventing the first computer-generated musical tones. A pair of researchers from the University of Cantebury have now restored the first-ever recording made from Turing's "synthesizer." Turing figured that if he rapidly played clicking sounds at set intervals, the listener would here them as distinct tones corresponding to musical notes. For instance, playing the click on every fourth cycle of a computers' CPU produces a "C" tone, exactly like a modern synthesizer.
