Date posted: 19/06/2012 Bioinformaticist Robert MacCallum of Imperial College London and colleagues have adapted DarwinTunes — a program that produces 8-second sequences of randomly generated sounds, or loops, from a database of digital “genes” — to be accessed online. Almost 7000 participants rated each sound loop, played in a random order, on a 5-point scale from “can’t stand it” to “love it.” In a musical take on survival of the fittest, the highest-scored loops went on to pair up with others and replicate. Each resulting generation was rated again for its appeal. After about 2500 generations of sound loops, what started out as a cacophony of noise had evolved into pleasant strains of music. MacCallum and colleagues hope future incarnations will enable up to a million users to log on and participate. “Having so many users will help the music evolve a lot faster, and then, who knows?” says MacCallum.
