    function [out, bufferout] = filter_overlap(in, bufferin, filter,L)
% Function filter_overlap
% By Maxime Maury
% 05-04-22
% Input:
%   in:         signal to process
%   bufferin:   last M-1 values of the signal
%   filter:     filter coeeficients of length M
%   L:          last sample take after filtering
% Output
%   out:        filtered signal
%   buffer_out: last values of the signal

M = length(filter);

% Overlap-save: add buffer of length M-1
out = [bufferin ,in];

% Save the new buffer
bufferout = in(L-M+2:L);

% Apply the filter
infiltered = conv(out, filter);

% Discard the first M-1 values
out = infiltered(M:end);
