That sounds like critical bands; in the recording, you'd actually captured something that would appeal to pinnae effects, giving elevation cues you would not have expected to capture without binaural recording techniques. Some speakers also generate similar cues (if the frequency content is there in the source material), so that the soundstage has an upward 'bulge' in the middle, where HF signals seem to climb above the left-right soundstage. Waveguide technologies can sometimes be responsible. Cheers ppl

I personally think that these things can sometimes happen due to weird room reflections , resonances modes, the position of the television etc interacting weirdly with certain frequencies. I will never forget one of these events when I recorded bird sound. Played back on my crappy laptiop speakers the birds literally seemed to be localised over a metre and a half above the laptop. Whats more everyone could hear the same effect ! As it only worked on that laptop and I only had it in one position in the room I reached the conclusion it was some weiird reflection thing off the screen/room. I wish I could remmeber which recording it was ....
