【语音处理】基于matlab GUI录音与音频处理【含Matlab源码 181期】

一、简介

基于matlab GUI界面处理录音与音频

二、源代码

function varargout = sigany(varargin)
% SIGANY M-file for sigany.fig
%      SIGANY, by itself, creates a new SIGANY or raises the existing
%      singleton*.
%
%      H = SIGANY returns the handle to a new SIGANY or the handle to
%      the existing singleton*.
%
%      SIGANY('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SIGANY.M with the given input arguments.
%
%      SIGANY('Property','Value',...) creates a new SIGANY or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before sigany_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to sigany_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
