% Homework 1.2 - This file is supposed to reverse and slow down a Judas Priest song
% Begin by clearing the console and all saved memory.
clear;
clc;
%Open the wave file and get its length, sample size, and sampling rate
%Make sure the file is in your present working directory for matlab
[data,sample,rate]=wavread('jpforward.wav');
%Play the file once at normal speed
wavplay(data,sample);
%Creates an array for reversing the data and then reverses it
Length_Array=size(data);
Length=Length_Array(1);
data_reverse=zeros(Length,1);
for j=Length:-1:1
data_reverse(Length-j+1,1)=data(j);
end
%Plays the song and saves it to a file
wavplay(data_reverse,sample);
wavwrite(data_reverse,sample,rate,'jpreverse.wav');
%Now to slow the song down
%To do this all you do is lower the sample rate
%Perhaps twice as slow?
slowsample = sample/2;
wavplay(reversedata,slowsample);
wavwrite(reversedata,slowsample,rate,'jpreverseslowed.wav');
