function [IRs] = llado2022_extractirs(sofaFileName,lat_angles,fs)
%LLADO2022_EXTRACTIRS extract impulse response signals for the given lateral angles from a sofa file
%
% Input parameters:
% sofaFileName : filename of the HRIR set in sofa format
% lat_angles : vector of lateral angles to extract
% fs : sample frequency
%
% Output parameters:
% IRs : Impulse response according to the following matrix
% dimensions: direction x time x channel/ear
%
% LLADO2022_EXTRACTIRS extracts the impulse responses as a SOFA file
