Construction of Electronic Timbre Dictionary for Score Representation of Computer Music

在20世纪创立的计算机音乐中，不仅器乐的音色起着重要作用，环境音和电声的音色也起着重要的作用。然而，这些没有用符号表达的事实阻碍了音色理论在乐谱上的统一表达和音色理论的建立。因此，构建了一个原型系统“电子音色词典”，作为使用音色符号的音色操作工具。该系统在服务器端有声音数据库，客户端用户具有以声音注册和回放为基本功能，以拟声词为特定功能的搜索功能。此外，还开发了3D图形用户界面，将声音(流)表示为粒子，这种直观的表示提高了系统的运行效率。基于这个系统，我们现在准备研究新的基于IPA的音色符号。

In computer music which was founded in the twentieth century, not only the timbres of instrumental sounds but those of environmental sounds and electroacoustic sounds play an important role. However, the fact that these are not expressed in symbols have prevented from the unified expression onto a score and establishment of timbre theory. Therefore a prototype system "Electronic Timbre Dictionary" was constructed as an timbre operational tool using timbre symbols. The system has sound database in server side, and a user in the client side has a sound registration and play back as a basic function, and search function using onomatopoeia as a specific function. Moreover, 3D GUI (Graphical User Interface) was developed in which a sound (a stream) is expressed as a particle, and this intuitive representation improved operational efficiency of the system. Based on this system we are now ready to study new IPA-based timbre symbols.
