The listener is exposed to to a set of directional waves coming from the speakers (one directional wave per speaker) which combine into an approximation of the original soundfield - there is no conflict between the two views. If the approximation is good enough, the way it is constructed becomes irrelevant and you won't hear the speakers as separate sources. A phantom (between the speakers) source will result in superposition (i.e. interpolation) of HRIRs, even when listening to a speaker system. If the same happens when binaural signals are synthesized, that should not be a problem if it wasn't one for the speakers system. In other words, the fact that interpolating HRIRs will not result in the exact HRIR for the intented direction should be irrelevant IFF the signals that are combined would produce a convincing soundfield when reproduced over speakers. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
