audio - Stereo sound separation into three sources


Whenever we listen stereo songs, one part of the audio like voice hear at the center of the head, and other parts are nearby left ear and right ear. If I represent center part by C, and other parts by L' and R', We may model our original left and right channel as,


enter image description here



L' + C = L and,


R' + C = R.


As, common part of L and R channel comes in C vector, L' and R' are uncorrelated. Now we can say, (alpha + beta = pi/2)


Is this modelling correct as per the listening scenario for stereo sound?
