clear;

[data, srate, brate] = wavread('jpforward.wav');  %reads wav file and stores to array
wavplay(data,srate); %play the song normally

x = length(data); %length of song array

jpreverse = zeros(x,1);
counter = 1;

for i = x:-1:1  %for loop from end of song to beginning
    jpreverse(counter) = data(x);  %reverse song into jpreverse
    counter = counter + 1;
end

%play reversed version of song
wavplay(jpreverse, srate);

wavwrite(jpreverse, srate, brate, 'jpreversed.wav');

%create and play song reversed but slower
wavplay(jpreverse, srate/1.75);
wavwrite(jpreverse, srate/1.75, brate, 'jprevslow.wav');
