Error using horzcat
Dimensions of arrays being concatenated are not consistent.
data = [x y];

% get a section of the sound file
[x, fsx] = audioread('Machine_Gun.wav');   % load an audio file
[y, fsy] = audioread('Dry_Synthesized_Machine_Gun.wav');   % load an audio file
x = x(:, 1);      % get the first channel
y = y(:, 1);      % get the first channel

nx = length(x);   % signal length
ny = length(y);   % signal length

yPad  = y;
yCrop = y;
xPad  = x;
xCrop = x;
if nx > ny
    yPad(nx) = 0;
    xCrop    = xCrop(1:ny);
elseif nx < ny
    xPad(ny) = 0;
    yCrop    = yCrop(1:nx);
end

c1 = corrcoef(xPad, yPad);
c2 = corrcoef(xCrop, yCrop);
