> have you ever walked by a bunch of musical sound coming out of a room and thought to yourself, "wow, those live musicians sound great" only to discover it was just a stereo playing?

Yes, I have. With the right combination of speaker setups and hi fi recordings, it is possible to fool yourself into believing there are musicians there.

Note that sitting in front of a speaker setup playing a carefully selected recording is not the same as the scenario above. We do not yet have the technology to fool someone walking by a room, especially for orchestral works or even an acoustic drum kit.

But I have experienced exactly this. Not an orchestra, but a recording of a band. I guess you can split hairs about the definition of "fool", but I have been fooled as you describe.

Well that's exciting then! What was the setup??
