Spatial audio synthesis quality is measurable against a real-source reference.

Evidence

A considerably simpler case is the evaluation of spatial sound synthesis methods without aiming for reproduction of the recorded acoustic conditions. In synthesis methods, a specific spatial attribute is to be controlled, and the reference case can also often be created. For example, in virtual source positioning methods, the synthesized position of the virtual source can be measured relatively simply by using appropriate psychoacoustic test methods. The possible degradation of overall quality should also be measured, which is relatively simple to do, since the reference case can be generated by positioning a real source in the panning direction, thus enabling the comparison of the virtual and real sources in listening tests. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2377
