| 摘 要： | 采用若干个不同延时系数的单回声FIR滤波器进行并联,构成一个早期反射滤波器,将该滤波器与Schroeder滤波器再并联,得到改进的Schroeder混响模型.利用MATLAB软件对该改进的模型进行仿真实验的结果显示,改进模型的早期反射得到了恢复,能够获得良好的具有完整的直达声、早期反射和后期混响成分的脉冲响应波形.利用...

| Abstract: | By paralleling Schroeder reverberation model with early reflection filter which contains several different Single-echo FIR filter in parallel,an improved model of the natural sound reverberation has been presented.The results by simulating with MATLAB show that the early reflection has been restored in the improved model,which completely contains direct sound,early reflection and reverberation.This improved model on the MATLAB can realize the design of Digital Reverber software. |
