How can be a buffered signal reconstructed?

I have a signal which i buffered with 2/3 overlap. Now i want to rebuild the buffered signal, but i don't know how to do it. To buffer it i used

length(signal)=112935;
wsize=256;
overlap(170);
buffer(signal, wsize, overlap);

This is now a 6y/o question, but I've been searching for an answer and didn't find one. So I have written the code myself and now I am posting it hoping someone-someday might find it useful.

General inverse buffer function:

function res = ibuffer(buffered, overlap)
    A = buffered(overlap+1:end,1);
    for i = 2:(size(buffered,2)) 
        B = buffered(overlap+1:end,i);
        A = cat(1,A,B);
    end
    res = A;
end

Tried on an actual signal to check if it works:

And it seems like it does... :)
