摘要

電聲音樂(electroacoustic music)係基於電子聲學(electroacoustics)轉換科技之進步，作曲家可透過電腦整合各種電子與原始聲音素材透過各式數學變換(transformations)來創作電腦音樂。本文試圖以電腦軟體與程式做為音樂創作之媒介，透過電子聲音做為音樂創作之來源，運用各種可能的技法製造出聽者從未體會過的音樂聆賞經驗。本文亦將探討運用電腦軟體製造各種可能的電子聲響，產生新的音色，給予作曲者更寬廣的創作空間，希冀可超脫出舊有聲響之框架，蘊含著無限音色的可能性。文中將針對各種電聲音樂的創作技巧與其應用，包括微分音律之使用、未定性的美學、聲音合成法則、噪訊的應用、音團堆疊、濾波器設計等六項技術原理與美學上作一探究，希冀可為新一代的電腦音樂創作者打下良好的根基。

Electroacoustic music is based on the transduction technology development, to let composer compose music with various mathematic transformations for the integrated sound materials. This article makes attempt to operate the computer software and program as the media for the music composition, use the electrical sound as the source for the composition, and apply all of the possible techniques to provide the new experiences for the listeners. This paper also discusses how to use the computer software to produce all of the possible electrical sonority to generate the new timbre, to provide the composer a wider space without any traditional sound limitation. The six important composition techniques for electroacoustic music includes the application of microtonal tuning system, aesthetics of indeterminacy, sound synthesis methods, noise application, overlapped cluster, and filter design, which can be used by the new generation of composers as a good groundwork hopefully.
