摘　　要：给出几种数字混响器模型,从简单的梳状滤波器混响模型到较复杂的Moorer混响模型,对各种模型的原理、结构和参数进行了分析和研究,运用Matlab软件进行了仿真实现,根据系统的脉冲响应和频率特性,讨论和比较了各种模型的优缺点.研究和仿真结果表明:全通滤波器混响模型能够实现一定质量的人工混响效果,同时结构相对简单;Moorer模型则具有最好的声音自然度,但结构和参数设计较为复杂.Several models of digital reverberators from a simple comb-filter reverberation model to a more complex Moorer reverberation model are presented.The principles,structures and parameters of these models are analyzed and investigated respectively and their implementations and simulations are conducted with Matlab.The merits and demerits of the different models are compared according to impulse responses and frequency characteristics of the system.The research results show that the all-pass filter reverberation model can achieve a certain quality of artificial reverberation effect and has a relatively simple structure,while the Moorer model has the best effect in terms of the naturalness of sound,but its structure and parameter design are more complicated.
