I've been meaning to ask about this. Is one supposed to be able to tell whe=
ther a recorded sound is coming from above you, for example, with proper bi=
naural recordings? I've listened to a few I found on the web, and can't rea=
lly convince myself that I can. Yet with live sound, I can tell if it's com=
ing from above me.

Even if the recording is low quality, it should still sound binaural. Just =
like 3D photography still works with grainy photos. It's not a very expensi=
ve system, so people might not be expecting much.

I wondered about that too. It might be that they just disable the earphones=
while recording.
