Holophony: "

image: Jason Sims

Plug in some headphones and listen to the following recording. You’ll hear a match being lit, then a matchbox shaken and moved around you — behind and in front, then above and below. I’ve heard clever effects like this before, but nothing so realistic, and nothing that captured vertical space with just left and right channels. You can almost see the sound moving about — but only with headphones — speakers will simulate planar movement but not the full 360 degrees.

Developed in the 1980s by Hugo Zuccarelli, Holophonic Sound uses the same ‘multiple exposure’ premise as that used to create holographic images (‘holograms’). Holophonic Sound is produced by recording the interference pattern generated when the original recorded signal is combined with an inaudible digital reference signal. The recorded sound produced is so realistic, some people claim they can smell sulphur when they listen to a holophonic recording of someone striking a match!
