[OT] holophonic 3Dsound

my god! that could kill 5.0!!! ive never ever heard of anything that could
do that, and the trippy part is that its just a stereo pair!!!! have you
read evrything on that site? it doesnt seem to have any directions on
implimentation

wiki means:

Holophony (or holophonic sound) is an audio recording technique, designed by Argentine researcher Hugo Zuccarelli, which operates on a similar principle to Holography, except it applies these principles to sound and audio recording. It uses a multiple exposure technique where an original recording is combined with a reference recording, and the resulting interference patterns are recorded. The result has been reported to be realistic and life-like three dimensional sounding audio recordings which have been said to exceed the realism of stereo sound.

anyone ever used this baby:

why isnt it more widespread? i mean it's amazing. am i wrong? though i guess
this isn't somthing to keep going off about in max list

According to David Malham, there is a close relation between Holophony, Wave Field Synthesis and Ambisonics.

do you think it would be possible to make a dsp plugin that could possition
audio on the Y axis? it seems possible. i mean if you can record with this
technique ( holophonics) it stands to reason you can generate the same
effect. i mean you can make a stereo faker!!! there are thousands of em

I would imagine this is possible. If holophoncs uses some sort of mixing between the raw recording and a reference recording, then in theory I suppose they could be mixed / convolved somehow to give spatialization cues. The specifics would probably be pretty complex, but when it finally worked, it would probably boil down to a set of adjustable parameters for distance, strength, and maybe some frequency filtering that affects the perception of these.

Sounds like fun to try out! Surround sound in headphones.... heck yeah!

yeah but this is so much more then suround isnt it? am i mistaken? CAN
5.1do UP and DOWN? i mean thats the kicker isnt it?

For me, yes. Providing surround with stereo source is one issue, top down thingie is another. I guess this technique has nothing to do with HRTF and so right? This is a rather old technique as far as I've heard, and not much have been done to improve it. A google investigation pointed me to the same (silly)website over and over again.

Can someone give any ideas about the technique involved here? This is achieviable with a mono recording and post processing right? The reference sound mixed with the original recording; one should be able to synthesize them with some convultion techniques I think.

Tracking the listeners head motion and arranging sound source spatialisation according to that info realtime woudl be cool,does that have any chance of being applicable? I'm really curious.
