【信号处理】基于matlab GUI语音降噪混频【含Matlab源码 297期】

一、简介

基于matlab GUI语音傅立叶变换降噪混频

二、源代码

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