% 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.".
Message
This is one of the famous songs for Backward masking. (a) The forward says, "Beyond the Realms of Death". (b) The backward says, "I took my life".
