That would be a 132 point moving average filter, which you can do with
b = 1/132*ones(132,1);
output = filter(b,1,input);

I agree, in fact that's why I suggested it in your earlier, duplicate posting (that I guess you forgot to check). http://www.mathworks.com/matlabcentral/answers/35683-smoothen-sound-signal
