Howdy y’all,

I’m doing some investigations preliminary to implementing a room acoustics auralization system and want to get some input from the community.

Is there any good literature on the perceptual difference between a phantom source (e.g. between a stereo pair) and a real source (e.g. center channel)? I am interested in more than just simple localization: width, resolution of multiple phantoms, etc.? Is perception of a phantom source the same when panned between a triad or a pair of loudspeakers? My basic understanding is that phantom sources are wider or blurrier than real ones, has this been specifically tested?

Any opinions or references are welcome.

Have a great summer,
