It's a two channel surround sound in a level of it's own.

Sorry, I don't understand. The match-box demo on the wikipedia 'holophony' page sounds like binaural-recording to me.

It's a shame there's no documentation on how exactly it's done. Having read on the subject it seems like some form of surround matrix recording (multiple mics, clever summing), but oddly enough it's never explained in detail, and doesn't seem like it has been utilised much anywhere.

good caturday to you too.

the definitive difference (to simple binaural) seems to be the usage of some sort of reference mic, or reference mic matrix to catch important spatial reflections/information, mixed with something akin to binaural mics. The technique seems simple enough with no need for any proprietary surround processors. Maybe somebody should drop a mail to Italy about this.

bad ears and brain but decent headphones. Nothing in the matchbox demo says "reference-mic-matrix" to me.

A hologram's appearance varies with the position of the viewer's eyes. Am I supposed to be moving my ears relative to my headphones to perceive the audio effect

could you link some of the binaural recordings that sound the same to you Andrew, i never heard any that sound like holophonic, but would like to.

if you are able to speak German: the German version od the wikipedia article is much more in depth

theres still only left and right really in that, where as holophonics have front, back, left, right. maybe i am deaf...

My understanding is that binaural and holophonic are almost interchangeable terms, HOWEVER I think holophonic denotes some sort of post-processing, where binaural is usually a straight stereo recording similar to how we actually hear.

I worked with a friend in LA back in the 90's that had a Sony binaural microphone that looked like a manachin head. He recorded everything to stereo DAT. Simple stereo files used for processing with no need for added reverb or processing.

It was challenging because when you mixed bands, choirs, etc. you had to actually move the players (sort of like using a mixer) in order to adjust volume, etc.

VERY cool stuff. I still have a lot of the recordings backed up somewhere.

yep, and holophonic sound also has up and down, and the sound isn't very subjectible to changes between different people (earshapes etc) listening to it. The match box through decent headphones should go around the head and down the back (quite low), and it's not a subtle effect at all.

binaural recording is not interchangeable term with this more advanced method. binaural recordings generally refer to stereo audio recorded using dummy mics/heads. A few mic manufacturers actually sell these dummy mic sets.

it does in the scarce documentation if you follow the wikipedia links.

Is there an effect plugin capable of imitating holophony?
