摘　　要：本课题基于信号处理技术和MATLAB,综合运用GUI界面及相关函数设计与实现一个音频处理系统。系统图形用户界面由窗口、光标、按键、菜单及文字说明等对象构成,用户通过选择对应的按键,激活后台编写的基于MATLAB的对应的信号处理功能,实现对音频信号的采集提取、调整、变换及加噪滤波等处理,并通过图形显示出来。经测试,系统界面清晰,操作简单,使用户可以更直观、更方便地分析音频信号,获得所需实验数据。Based on signal processing technology and MATLAB,this paper designs and implements an audio processing system by comprehensively using GUI interface and related functions.The graphical user interface of the system is composed of window,cursor,key,menu,text description and other objects.By selecting the corresponding key,the user activates the corresponding signal processing function based on MATLAB written in the background to realize the processing of audio signal acquisition and extraction,signal adjustment,signal transformation and noise filtering,and display it vividly through graphics.After testing,the system interface is clean and simple to operate,so that users can analyze audio signals more intuitively and conveniently and obtain the required experimental data.
