% Virgil Hsieh
% Homework 1.2: Judas Priest song backwards and slowed down.
% The following two lines clears the screen and all variables
clc
clear all
[arraysound, sample, bitsize] = wavread ('jpforward.wav');
% Reverses the array
for walker = 1 : length (arraysound)
backwards (length (arraysound) - (walker - 1)) = arraysound (walker);
end
% This plays it backwards
wavplay (backwards, 44100)
% Makes a wav file for the backwards version
wavwrite (backwards, 44100, 'Backwards44.wav');
% I slowed it down for you, so that you would know that I know how to do it
