Despite recent consumer uptake of surround sound systems and the existence of a number of studies into spatial audio attributes, there is currently no system to train listeners in the detection and discrimination of the spatial attributes of reproduced sound. Timbral ear training has been shown to increase response consistency in listening tests, but a number of obstacles must be negotiated in order to successfully implement an ear training system for spatial aspects of sound reproduction. The first of these is the determination of which spatial audio attributes are appropriate. This paper describes the formulation of a new spatial audio paradigm, by testing previously documented attributes against specific selection criteria, and including, modifying or rejecting them accordingly.
