% Jun Hyeong Park 
% ECE 301 HW #1_ Hidden backward message

Fs=44100;
name='jpforward.wav';
conforward=wavread(name);   % generate a column vector           
conback=flipud(conforward); % reverse this column vector
wavplay(conback,Fs)         % play backward at 44100hz sampling rate. 
pause(1)
wavplay(conback,Fs/2)       % play backward at 22050hz sampling rate.

% (a) The forward says ,"Beyond the Realms Of Death"
% (b) Backward has a message and that was "I took my life.".
