随着科技的日益进步，传统的音视频行业与数字信号处理结合的越来越紧

密，数字信号处理领域的科技成果越来越普遍的应用于多媒体领域，并且极大地

推动了多媒体行业的发展。数字音频效果处理系统的应用就是音频信号处理领域

的一个很好的例子。

首先，本文介绍了数字音频处理技术的发展和音频系统的组成，叙述了数字

音频效果的分类、基本原理。本文介绍和设计的基于DSP的数字音频效果系统可

对输入信号进行高速处理，产生各种常用的效果，并且这些音频效果可选、参数

可调、使用方便直观。文章实现了八种以上的音频效果，包括延迟、回声、合唱、

镶边、振音、颤音、混响、相移、哇音和失真等音效，并详细的分析了这些音频

效果的产生原理及实现；介绍了音效处理在DSP平台上的算法实现方法和改进，

包括研究在硬件平台上将现有理论音频效果算法，并通过优化，提高效果的质量。

最后，论文介绍了音效性能评价方法与传统的音频质量评价方法的不同，详细介

绍了各类音频效果的性能测试方法，由测试结果显示改进后的音效性能有了很大

程度的提高。

最后，论文还对整个音频效果处理系统设计工作进行了总结，指出了一些音

效性能的不足。另外，论文讨论了系统的改进意见和系统今后研究的方向。With the advancement of technology, industry and the traditional audio and video digital signal processing combined with increasingly tight

Scientific and technological achievements dense, digital signal processing used in the increasingly popular field of multimedia, and greatly

Promote the development of the multimedia industry. Application is the field of digital audio signal processing audio effects processing system

A good example of this.
