%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

fprintf "Playing the original file."
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

fprintf "Playing 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.

fprintf "Playing reversed song at half speed."
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_0.5Speed');
