Computer Music Sound Synthesis from Timbre Symbol

为了表现、交流和保存计算机音乐艺术，必须对音色进行符号化。首先通过心理声学实验研究了一般环境声音的感知特性。IPA（国际音标）和“平假名”都被用作音色符号。从实验中澄清的事实包括，方差归一化的符号数从中间字符串为一个音色写在“平假名”很大程度上从0.27到4.54。我们也一直在开发“电子音色字典”，使音色搜索从音色符号作为计算机音乐家的支持系统。实现了MacOS、Windows和Linux的跨平台功能和多语言功能。此外，该系统向一般用户开放，并可通过网络使用。

In order to represent, communicate and preserve artistic computer music, it is necessary to symbolize timbre. Firstly perceptive characteristics are studied for general environmental sounds by psycho-acoustic experiments. Both IPA (International Phonetic Alphabet) and "hiragana" were used as timbre symbols. The clarified facts from the experiments includes that the variance normalized by the number of symbols from median strings for one timbre written in "hiragana" largely varies from 0.27 to 4.54. We have also been developing "Electronic Timbre Dictionary" which enables timbre search from timbre symbol as a supporting system for a computer musicians. In this term, functions of cross platform for MacOS, Windows and linux, and multilingualization were realized. Moreover, the system was open to general users and available via network.
