%Read a wav file:
[data, sample_rate, bits_per_sample] = wavread('JudasPriestforward');

%Play the data from a wav file:
wavplay(data, .75*sample_rate);

%Reverse the song
backward_song = flipud(data);
sound(backward_song, .5*sample_rate);

%Save the wav file:
wavwrite(backward_song,sample_rate,bits_per_sample,'JudasPriestbackward');



%When the song is played forward the lyrics are clearly jibberish, even
%when slowed down.  However, when played in reverse at half speed, it
%sounds like he's saying "I took my life".
