●Attachment to sound

 At the beginning of 2014, I decided to use mathematics to create a sound (timbre) that even acoustic instruments (physical instruments) with a long history could not play! The depressed heart was replaced by a lively heart, and it continues to this day. What kind of sound it is depends on the person, but for me (I have experienced it several times in the past), it is "a sound that shakes the internal organs", and it is a sound that I want to listen to all the time, and if I can never hear it again, I will be tormented by a sense of loss. Even with professional live instrument performances and singing voices, there are many opportunities to feel that the sound is unpleasant (even though it should have rich irregular fluctuation components and overtones), and that may have been the motivation for my ambition. There was a physics believer who said, "It's impossible to surpass real instruments." No, no, it won't be long before the world of sound (as typified by AI) will be in an era where mathematics will be the focus of attention. However, (from past experience) a reductionist approach is bound to be a thorny road. Therefore, it is a translation of unraveling a complex system.
