Abstract

Spatial Matrix synthesis is presented in this paper. This modulation synthesis technique creates acoustic velocity fields from acoustic pressure signals by using spatial transformation matrices, thus generating complete sound fields for spatial audio. The analysis presented here focuses on orthogonal rotation matrices in both two and three dimensions and compares the results in each scenario with other sound modulation synthesis methods, including amplitude and frequency modulation. As an alternative method for spatial sound synthesis that exclusively modifies the acoustic velocity vector through effects comparable to those created by both amplitude and frequency modulations, Spatial Matrix synthesis is argued to generate inherently spatial sounds, giving this method the potential to become a new musical instrument for spatial music.

空间矩阵合成

本文介绍了空间矩阵合成技术。这种调制合成技术通过使用空间变换矩阵从声压信号中创建声速场，从而为空间音频生成完整的声场。本文的分析侧重于二维和三维的正交旋转矩阵，并将每种情况下的结果与其他声音调制合成方法（包括振幅和频率调制）进行了比较。作为空间声音合成的另一种方法，空间矩阵合成法专门通过修改声速矢量来产生与振幅和频率调制相媲美的效果，可以产生固有的空间声音，使这种方法有可能成为空间音乐的新乐器。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
