%   Input parameters:
%     ir       : Impulse response according to the following matrix

%
%   Output parameters:
%     y_est    : Estimated values for perceived direction and position uncertainty.
%
%   LLADO2022(...) is a model for estimating the effect of head-worn
%   devices on frontal horizontal localisation. A neural network (NN) was
%   trained using binaural features of a dummy head wearing different
%   head-worn devices to predict the data from a perceptual test using the
%   same devices. If you want to use your own data, please find in the
%   script 'demo_llado2022' the whole procedure.
%
%   Optional input parameters:
%
%     'stim'             stimulus. If empty, 250 ms of pink noise
%
%     'fs'               (DEFAULT = 48000)
%
%     'NN_pretrained'    if empty, a pretrained NN is used. 
%
