Sounds are always the same distance away. I've experianced that with binaural recordings as well. Is there a surround sound method that will reproduce actual depth enough so that you could track the movment of a fly in a room? I'd love a system where i could hear a fly moving towards my face, veering off a few inches away, moving at a diagonal to 5' away then zig-zaging back and around my head.
Would the lack of a visual component effect that strongly? I can still locate a fly without seeing it. Can ambisonics do that with a good mic for the W?
