Sound Creation Based on Different Chaos Attractors Naruno Fujii1,

This paper describes sound creation without signal process-ing but with nonlinear differential equations. Usually sound creation is realized by using signal processing. However to understand the signal processing completely is difficult for amature users. And the quality of sounds is artificial than the sounds of real instruments like grand pianos and violins. So the purpose of this research is to create more natural and artistic sounds. So as to consider about natural and artistic sounds, 1/f fluctuation is also important element. Sound that gives good feelings for human’s ears includes kind of shak-ing. To realize that, using chaoses is so effective method. Then considering about to create various kinds of sound by using chaoses, it comes to necessary to think about frequency characteristics and other elements each chaos has. 1
