%Read the wav file in matlab
fs=44100;%sample frequency
[jp,fs,bits]=wavread('jpforward.wav');
wavplay(jp,fs);%forward version
pause(1)
jpbak=flipud(jp); %reverse the signal
wavplay(jpbak,fs);%play the reversed version
pause(2)
%Slow version with half frequency
slowfs=fs/2;
wavplay(y,slowfs);
pause(3)
%fast version with doubled frequency
fastfs=fs*2;
wavplay(y,fastfs);
%The forward message is "Beyond the realm of death".
%The backward message is "I took my life".
