MOORE2016_COCHLEA - performs outer and middle ear filtering

Program code:

function out = moore2016_cochlea( s, filenameFilter )
%MOORE2016_COCHLEA performs outer and middle ear filtering
%
%   Input parameters:
%     s : input signal
%     filenameFilter : name of the file containing the filter coefficients
%
%   Output parameters:
%     out : filtered signal
%
%   This code corresponds to the outer and middle ear filtering in the binaural loudness model moore2016
%   in the version for TVL 2016 based on ANSI S3.4-2007 and Moore & Glasberg (2007).
