基于ＭＡＴＬＡＢＧＵＩ的语音信号采集分析系统前一阵子用MA TLAB GUI做了一个语音信号采集与分析的界面。

功能包括录音、播放、时域、频域分析吧。

也导入本地文件进行分析。

效果如下：源码如下：function varargout = GUI_1(varargin)% GUI_1 MATLAB code for GUI_1.fig% GUI_1, by itself, creates a new GUI_1 or raises the existing% singleton*.%% H = GUI_1 returns the handle to a new GUI_1 or the handle to% the existing singleton*.%% GUI_1('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in GUI_1.M with the given input arguments. %% GUI_1('Property','Value',...) creates a new GUI_1 or raises the % existing singleton*. Starting from the left, property value pairs are% applied to the GUI before GUI_1_OpeningFcn gets called. An% unrecognized property name or invalid value makes property application% stop.
