A stationary listener will only sense the curvature if the source is quite near, less than half a meter or so, depending on the spectral content. For larger distances a moving listener can detect the curvature, but only indirectlty as the apparent direction of the source changes. Also note that 2-D WFS systems are optimized for a particular speaker line to listener distance, it's not possible to get exact wave synthesis every- where (it is possible for 3-D systems). And anyway the things will not work correctly if you are too close, less than 5 times the distance between the speakers or so. -- 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.
