【摘要】： 随着20世纪音乐家们在观念上开始探索新音响、新形式、新的表达方式的可能性,希望对创作实践有借鉴作用,越来越多的音乐家注意到空间对音乐表现力的突出作用。在计算机中通过数字手段人工调制虚拟声音的空间,以及有了多声道录音技术和播放技术等手段,使声源被固定于听众的前方或是传统固定位置的单点声源演变到多点声源的场空间中,并用各种手段使声源在定位、变位过程中营造动态音响效果,使音响空间的立体感增强,并且丰富声音的动态运动空间。声音空间是声学研究很早就关注的课题,今日则已开始进入新的境界。本文通过对声音空间问题的历史追述,及对其客观属性和主观属性的分析,并通过了解作品中体现的各种空间感的应用,来探讨与研究用数字技术来虚拟声音空间的必然性和重要性,实现手段和实现途径。从理论到技术上力从探研对声音的空间概念的认识由感性升华到理性,以使我们在创作中增强空间概念和音乐表现力的认识,为电子音乐的空间声场的创作积累经验。
[Abstract]:In the 20th century, musicians began to explore the possibility of new sound, new form and new way of expression in concept, hoping to be a reference to creative practice. More and more musicians have noticed the prominent role of space to the expression of music. In the computer, the space of virtual sound is manually modulated by digital means, as well as the technology of multi-channel recording and playing, etc. The sound source is fixed in front of the audience or the single point sound source in the traditional fixed position evolves into the field space of the multi-point sound source, and makes the sound source create the dynamic sound effect in the process of positioning and displacement by various means, so that the stereo sense of the sound space is enhanced. And enrich the dynamic movement of sound space. Acoustic space is a subject that has been concerned for a long time in acoustics research, but it has begun to enter a new realm today. This paper analyzes the objective and subjective attributes of the sound space through the historical review of the sound space problem, and through the understanding of the application of the various spatial senses embodied in the works. To explore and study the necessity and importance of using digital technology to virtual sound space, the means of realization and the way of realization. From theory to technology, it is necessary to explore the understanding of the spatial concept of sound from perceptual sublimation to rationality, so that we can strengthen the understanding of spatial concept and musical expressiveness in creation, and accumulate experience for the creation of spatial sound field of electronic music.
