Music By Natural Selection

maccallr writes "The DarwinTunes experiment needs you! Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet and we'd really appreciate some Slashdotter idle time. We recently upped the maximum 'genome size' and we think that the music is already benefiting from the change."

    I'm the site admin. Sorry for the inability to withstand slashdotting. This was supposed to only go in "Idle"...

    You can get to the actual evolving music bit
    via this ugly EC2 URL

    That link will not work in a few days from now (when I let go of the machine). Too stingy to pay for an elastic IP ;-)

    cheers,
    Bob.

    Lots of music makes use of square waves. Distortion guitar is essentially a square wave. It starts as similar to a sine wave, the guitar amplifier or processor clips it into a square wave.

    A square wave is a sine wave with added sine waves of odd harmonics to the fundamental.
