-As previously  described over e-mail, this is initial commit is part of the code that was designed for a specific experiment.
+Code that takes parameters of one geometry as input and gives one wav file of binaural signals.
 
-It is not quite yet what's needed in terms of specifying input parameters / obtaining outputs.
+The objective is to now use this as the basis for the development of the matlab -> web shell integration code.
 
-As the code currently stands, the user has to go into the 'user editable part' of the simulate_echo.m file,
-specify the geometry parameters (for a collection of geometries)
-and then run this edited function
-to obtain the collection of IRs as fields of a multidimensional structure array.
+Following that, the objective should be to add more user defined parameters that will work within the
+matlab -> web shell integration paradigm.
 
-Then the user can use the pick_ir.m function to get each IR corresponding to each individual geometry.
-
-I will soon push an extra .m file that takes parameters for one geometry and gives one binaural IR.
-
-We can then modify according to the requirements of the matlab -> web shell integration.

+Matlab help preample of simulateBinauralSignals.m:
+%Creates .wav file of 2sec long binaural signals for specific board dimensions and gaussian white noise stimulus
+%
+% The .wav is created in the current directory with filename is 'binsimecho.wav'
+%
+% INPUTS:
+% - dist (1st input argument) is the distance in meters
+% - azim (2nd input argument) is the azimuth in degrees (0 means straight ahead, positive angles are left and negative
+% are right)
+% - orient (3rd input argument) must be either 'horz' or 'angled' corresponding to flat and angled descriptions in
+% Papadopoulos et al. BSPC 2011.
+% - dirweight (4tht input argument) must be a nonnegative real scalar determining what is the relative weight of the
+% emission path to the echo path (i.e. due to directivity focus in the frontal direction of the source, the emission
+% which is directed upwards and backwards in our specific geometry is significantly attenuated, typically by factor in
+% the vicinity of 0.2)
