function stereo = lucy(data,fs,angle)
%help function
%data = input (sound source)
%fs=sampling frequency (44100)
%angle= the desired angle 
%this function bascially combined two results from the first function
%called headshadowingfilter. and throught this headshadowingfilter function we can get two
%results as we change the angle of the function.and this lucy function can
%combine those two results into one sound signal. 

stereo=[headshadowingfilter(angle,fs,data),headshadowingfilter(-angle,fs,data)];
%through this process two output results from the headshadowing function
%can be combined together as one signal
