碩士 === 國立交通大學 === 工學院聲音與音樂創意科技碩士學位學程 === 104 === The research of this thesis is attempted to take web browsers as the core of implementation, and to integrate with Web Audio API and HTML5 Canvas techniques to realize the possibilities of Granular Synthesizing on web programming. The server development framework, Node.js, is also used to make Granular Synthesis integrate with WebSocket technology, and finally develops a web application for sound interaction, which are the cross regional sound interactive design. The users in this system can also make the soundscape recording cross-regionally with Google Chrome browser. The recorded sounds will then be sent to the server, and finally be synthesized and listened by users with their web browsers throughout the places which be connected by the web. This research also takes literature reviews, which are related to granular synthesis, to explore the existence of the grain of sound and the coexistence between continuity and discontinuity. On the other side, the idea of integrating the web granular synthesizing with synchronous collaborative computing is inspired by both of the concepts inside Dennis Gabor’s Granulation Machine and Iannis Xenakis’s “Cloud of Sound”. In the practices studying, the works in Software Application, Sound Installation, Net Art and Video Art, which applied the concepts of granular synthesis, comes down to the two particular features on “the linkage from micro-scale to macro-scale sound listening”, and “the interaction between auditory familiarity and synthesized defamiliarization”. These features can be found inside the sounds of granular synthesis, and are also connected to the characteristics of Net Art. The sound interactive design in this system is constructed on the basis of the characteristics which appears inside the concept of Net Art. The entire features of sound and the interface design finally inherit the concepts of granular synthesis. The breakthrough of real-time recording and real-time sound interaction makes this sound interactive web application reaches the concepts of internet sharing and collaborative interaction on social network, which makes cross-regional soundscapes be connected with sharing concept in a group of people. The soundscapes can also be promoted to the higher interactive level and listening level by the medias of web technologies.
