民族器乐自相关分析中时窗的选择

Selection of Integration Window for the Autocorrelation Analysis of Chinese Instrument Music

对民族器乐作品时域信号进行相关分析时,选择不同的分析时窗对结果会有较大影响。以10首古乐的相关分析为例,试验讨论了获得最佳时窗的方法。在最佳时窗下分析出了每首乐曲的最佳听闻混响时间。

For calculating autocorrelation function of Chinese music,different integration window will lead to different result. The method of selecting optimum integration window is discussed based on analyzing autocorrelation function of ten pieces of Chinese classical music. Optimum listening reverberation time has been calculated in the optimum integration window.
