The direction of sound is defined to be the opposite of the direction of the intensity vector at each frequency band. The diffuseness of sound field is computed as ψ(k,n) = 1 − √ 2||$Re{W(k,n)∗U(k,n)}%|| $|W(k,n)|2+|U(k,n)|2/2% , (2) where || · || denotes thel2-norm of the vector and $·% denotes temporal averaging.

http://lib.tkk.fi/Dipl/2008/urn012233.pdf
Directional Audio Coding (DirAC) extends the scope of universal audio reproduction to real sound environments by utilizing existing microphones for analysis and arbitrary loudspeaker setups for synthesis of the perceptually relevant properties of the sound field. The human spatial hearing functions on the basis of multitude of cues.
Binaural Reproduction for Directional Audio Coding
http://lib.tkk.fi/Dipl/2008/urn012250.pdf
A recently proposed method for storing and reproducing spatial sound is Directional Audio Coding (DirAC) [1]. It is currently implemented for loudspeakers. In this thesis it is investigated if DirAC could be implemented for headphone listening. The ultimate goal is that one can record and store sound in some space and later, using head-
