% HW 1_2 Hidden Backward Message

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

Result

Playing forward sounds like "Beyond the Realms of Death"

Playing backward sounds like "I took my life"

Alumni Liaison

Basic linear algebra uncovers and clarifies very important geometry and algebra.
