function varargout = soundanalyze2(varargin)
% SOUNDANALYZE2 MATLAB code for soundanalyze2.fig
%      SOUNDANALYZE2, by itself, creates a new SOUNDANALYZE2 or raises the existing
%      singleton*.
%
%      H = SOUNDANALYZE2 returns the handle to a new SOUNDANALYZE2 or the handle to
%      the existing singleton*.
%
%      SOUNDANALYZE2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SOUNDANALYZE2.M with the given input arguments.
%
%      SOUNDANALYZE2('Property'.'Value',...). creates anew SOUNDANALYZE2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before soundanalyze2_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to soundanalyze2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one % instance to run (singleton)".
