摘要
从主观感知得分与客观音频特征两个角度出发,研究了37种常见的中国民族乐器音色的相似性.通过乐器的主观感知得分,提出1种可视化的主观音色描述方式,并计算音色感知向量之间的差异性得到主观音色的相似性矩阵,然后提取出表征音色的客观音频特征,并计算特征之间的差异性,得到客观音色特征的相似性矩阵.此外,本文还研究了音色的主观相似性与客观相似性之间的相关性.该研究有助于中国乐团的声学研究,也可为中国民族乐器的信息检索、音频检测等应用提供参考.
The timbre similarity of 37 Chinese musical instruments are studied from the perspective of subjective perception scores and objective audio features.Specifically,based on the subjective perception scores of instruments,a visually subjective timbre description method is proposed.Besides,timbre similarity matrices are calculated through the difference between the timbre perception vectors and subjective audio features respectively.In addition,this paper also discusses the correlation between subjective and objective timbre similarity matrices.The study is helpful for the acoustic research of the Chinese orchestra and could be served as a reference for tasks such as music information retrieval and audio detection.
