This article introduces the concept of Sound Signature audio visualization, a new form of amplitude waveform that also visualizes perceptually salient spectral features and their evolution over time. A brief review of existing research into timbre description and visualization is given. This is followed by an in-depth description of the algorithm. Rationale is given for the various visual mappings with reference to existing literature. The results of an online subjective evaluation survey are reported and discussed. The survey examined user preferences for the visual mappings used in Sound Signature visualizations. Results show a preference for inverse mapping of spectral centroid to the first component of the hue, saturation, value (HSV) color space.

一种新的基于语义描述符的音色可视化技术

本文介绍了 Sound Signature 音频可视化的概念，这是一种振幅波形的新形式，它还可视化了感知上显着的频谱特征及其随时间的演变。简要回顾了现有的音色描述和可视化研究。接下来是对算法的深入描述。参考现有文献给出了各种视觉映射的基本原理。报告和讨论了在线主观评价调查的结果。该调查检查了用户对 Sound Signature 可视化中使用的视觉映射的偏好。结果显示优先将光谱质心逆映射到色调、饱和度、值 (HSV) 颜色空间的第一个分量。
