The ability of humans to perceive the spatial location of a sound is of great practical and research importance.

The recent advances in computational power and acoustic measurement techniques have make the study of head related transfer function (HRTF) a rapidly growing area with potential uses in virtual reality audio applications.

This research focuses on:

• parsimonious representation of HRTFs
• efficient and less cumbersome HRTF measurement techniques
• applying binaural techniques in communication systems, for situations where the listener must hear more than one communication channel at a time. 

​Implementations of this kind of system can be used for pilots, air control towers and spatial audio teleconferencing.
