Holophonic Sound

quote:

Holophonic sound recordings should be played when the listener is wearing headphones, and played at a reasonable volume. This improves the listening experience because you can hear the true effect of the recording. Sounds are typically heard in a three dimensional fashion and by wearing headphones the noises seem almost realistic.

A famous example is the Pink Floyd album, "The Final Cut"

Hooked on Holophonics
But there’s a clever, patented variation on binaural recording that claims to go far beyond the simple microphones-in-the-dummy-head approach. It’s called holophonic recording, and the realism it produces, especially in the up/down dimension, is uncanny, eerie…even—as a friend of mine likes to say—freakadelic.

Ordinary holograms are produced by mixing reflected laser light with a second beam hitting an object from another angle; the resulting interference pattern of the two waves is what’s actually recorded on film. Expose the film to the same wavelength of light again, and a 3D image emerges from the interference pattern. Italian inventor Hugo Zuccarelli wondered whether a similar process could be used to record sounds, since after all, sound waves can form interference patterns with each other just as light waves can. His holophonic process starts with a type of binaural dummy head, but it reportedly records the interference pattern formed by mixing the sound with an inaudible, digitally superimposed reference signal. Zuccarelli believes that the human auditory apparatus, when listening to sounds, adds the same signal to the input, effectively decoding the interference patterns previously recorded. All that may sound like a bunch of mumbo-jumbo—and Zuccarelli certainly has detractors who claim “holophonic” sound is nothing more than binaural with maybe a few bells and whistles. All I can say is: hearing is believing. The holophonic recordings I’ve heard are simply remarkable—much more impressive than conventional binaural recordings—but I encourage you to listen for yourself and form your own opinion.

There is, of course, a little snag. As with all binaural recordings, holophonic sounds lose most of their spatial characteristics when played through ordinary speakers (though Zuccarelli has designed a special speaker system that enables holophonic sounds to be appreciated even outdoors by a large audience). As things stand now, you won’t be able to enjoy a holophonic soundtrack on your home theater system—no matter how many speakers it has—unless you and everyone else watching the film wear headphones. Nevertheless, a number of recording artists, including Michael Jackson, Stevie Wonder, and Pink Floyd, have employed holophonic technology in recordings or concerts, and it has also been featured in both films and commercials. Holophonic sound may be slow to catch on as a mainstream technology, but it’ll make your iPod sit up and go “Wow.”—JK

IS dat niet een techniek die jaren geleden al werd toegepast in diversen games maar door de opkomst van 5.1 een beetje in de vergetelheid geraakt is?

Geen idee meer hoe het heette, maar destijds ging men er ook vanuit dat je het beste geluid uit een koptelefoon kon krijgen.

Echt super, hij gaat echt van boven naar beneden en van links naar rechts. Nog veel realistischer dan 7.1 sound...

En die kapster haha

Godverdomme, hoe heette dat nou ook alweer wat ik bedoel?
Daar waren ze geloof ik in de tijd van de 3DFx kaarten enzo mee bezig.

Ook 3D geluid ipv dolby geluid in een plat vlak. En dit is daar volgens mij dan een betere versie van.

Iemand?
