基于MATLAB-GUI语音信号的采集分析系统.doc

基于的语音信号采集分析系统前一阵子用MATLABGUI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. All inputs are passed to GUI_1_OpeningFcn via varargin.% *See GUI Options on GUIDEs Tools menu.
