一种古琴音色重构仿真方法及其实现

Reconstruction and Simulation Method and Its Implementation for GuQin Tamber

为促进古琴艺术的传播,通过对古琴音色的分析,在建立古琴音色库的基础上,从古琴琴弦振动理论和音律学理论入手,利用傅立叶变换分析了古琴音色的频谱特征,并基于加权柯西函数,给出了重构古琴音色的策略。然后,通过采用基于音色数据库和音色重构两种方法,对古琴音色进行计算机仿真,建立了一个初步的古琴音色仿真系统。实验证明,通过重构音色进行仿真的计算方法,是古琴音色仿真的一种有效方法。

A Guqin timbre base was introduced through timber analysis and its spectrum specification was analyzed using Fourier transformation based on theory of Guqin srting vibration and temperament. Then a reconstruction method for Guqin timbre was proposed based on weighted Cauchyfunction. Finally a timbre simulation system for Guqin was worked out using timbre database and reconstruction. It has been proved by experiment that the computing method of timbre reconstruction is effective for Guqin timbre simulation.
