forward=wavread('jpforward.wav');              
wavwrite(forward, 44100, 'Forward.wav'); %forward 
backward=flipud(forward);
wavwrite(backward, 44100, 'backward.wav'); %backward
wavwrite(backward, 22050, 'backward22050.wav'); %backward@22050

Playing forward sounds like "Beyond the Realms of Death"

Playing backward sounds like "I took my life"
