基于MATLAB-GUI语音信号的采集分析系统

精品文档 1欢迎下载 基于 的语音信号采集分析系统 前一阵子用 MATLAB 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 All inputs are passed to GUI 1 OpeningFcn via varargin See GUI Options on GUIDE s Tools menu
