%First use the wavread command to get the data, sample rate, and bits per
%sample of the judas priest file.
[data,sample_rate,bits]=wavread('jpforward.wav');
%Next, play the original file normally
wavplay(data,sample_rate)
%Then we have to reverse the song using the command fliplr
data_rev=flipud(data);
%Next we have to play the reversed song
wavplay(data_rev,sample_rate)
%Then, to play the song slower, simply multiply the sample rate by a
%fraction. Here, I will use 1/2 the rate.
wavplay(data_rev,sample_rate*0.5)
%Lastly, I will write the backwards song using the wavwrite command
wavwrite(data_rev,44100,'Backwards_at_RegularSpeed');
wavwrite(data_rev,22050,'Backwards_at_slowSpeed');
