⛄二、麦克风实时时域和频域图简介

麦克风实时时域图是麦克风接收到的声音信号的振幅随时间变化的图像。它可以显示声音信号的波形，帮助我们观察声音的强弱、持续时间和频率成分等。

麦克风实时频域图是麦克风接收到的声音信号在频域上的表示。频域图可以通过对时域信号进行傅里叶变换得到，它展示了声音信号在不同频率上的能量分布情况。通过观察频域图，我们可以了解声音信号中不同频率成分的强度和占比，进而对声音的特性进行分析和处理。

⛄三、部分源代码

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