It will be the nearest speaker only if the direction of the source is orthogonal to the line array. What goes on is that the waves produced by the secondary sources (speakers) combine into a wave as would be produced by a real source in a particular direction and at a large distance. At least within the bandwidth which does not produce spatial aliasing, your ears/brain have no information at all to identify the speakers as separate sources, so there is no precedence effect involved. 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.
