Is there an effect plugin capable of imitating holophony?

[championrabbit]

I don't understand why binaural recording wouldn't provide (potentially) all the acoustic information necessary for the brain to be fooled, so long as the recoding was made using real/fake ears/body to provide tonal filtering.

The brain uses a combination of stereo and tonal decoding to asses direction; so long as these variations are accurately recorded, why would anything more complex be necessary?

[AndrewAD]

I'm wondering the same. If binaural recording is done well, it should in theory reproduce all directionality, including up and behind.

I see what the wikipedia article says, but an open-encyclopedia is only as credible as its info can be verified, and I can't verify anything in that article. No references or any mention even of binaural recording. If there's is such a thing as holophony, it seems for practical purposes useless, unless it's somewhere documented. I'll be delighted if it's something practical, with any advantage over binaural recording.

because binaural dummy head recordings sound like glorified stereo mics, maybe? None of them provide as accurate spatial information as the holophonic sound technique.

yes you can.

Ever heard of google?

US Patent #4680856, http://patft.uspto.gov/netacgi/nph-Pars ... Zuccarelli, describes "holophonics" in general. The patent involves an exceptionally detailed mold of the human head.

I seem to recall that the literature from the 80's included a claim that the ear actually emitted a "reference tone," analogous to the laser used in visual holography. But I don't see any such claim in either the web site or the patent. As far as I can tell, "holophonics" looks a lot like binaural with extra attention to the details. The holophonics cassette used a lot of near-field effects (woman whispering near your head, box of matches being shaken near your head, electric shaver, etc.) which are impressive with regular binaural as well.

There are a number of HRTF plug-ins that do an excellent job of binaural spatialization, including the WaveArts Panorama 5 and one we'll be releasing later this year.

But there is another kind of sound recording that is even more realistic - Holophonic Sound. 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! It appears that Holophonic Sound waves stimulate our brains to reproduce very realistic and truly three dimensional sound within us, thereby stimulating other corresponding responses that our brains expect to accompany the sound, (like scents or other sensations). Even more interesting is the fact that researchers report that some hearing impaired people can "hear" Holophonic Sound - again because it stimulates their brains even though their audio receiver mechanisms are not working properly.

Use Google people. it's not that hard.

I have Googled; I do find people copying each other's words without knowing what they're talking about, but I don't find why anything more than binaural recording would be needed to provide all the acoustic info necessary to fool the brain. I find this:

Zuccarelli certainly has detractors who claim "holophonic" sound is nothing more than binaural with maybe a few bells and whistles.

The referenced patent claims only a process for manufacturing head-models suitable for binarual recording.

I seem to recall that the literature from the 80's included a claim that the ear actually emitted a "reference tone," analogous to the laser used in visual holography.

If that's true, I suppose the same ear should emit the same reference tone when listening to binaural recordings, giving you holophony.

Well.. Googling is hardly "verifying". You'll more likely run into "circular web quotation" which is no more useful than circular argumentation. (Not saying that's the case here... )

BTW, I just thought of this new binaural invention. You can probably make a lot of money from it, so if you do, send me some:

Simply use real, living person, and have two small laser distance measuring devices measure the vibrations of each eardrum. Translate the vibrations into perfect audio recordings using the patented processing algorithm of your choice. (Something that involves physical modelling of the small bones of the ear seems a good and impressive way to go.)

Only persons suitably free from wax build-ups need apply for the job as human pickup.

even better, just attach an xlr out to each of the "hearing tubes" in your "human hearing system" (im no doctor; these are my own medical words). then just figure out how to model your humans brain in computer software codes and decode the ear waves coming from your xlr head on your personal pc computer. you can also make a little line in to hook up your ipod to listen to and bypass your ears completely so the sound rays go straight to your humans brain. then you won't disturb anyone while you listen to music during the quiet times!

actually i should mention that my brother and i tried all this with our dads tools (he works at wal-mart) and my behringer mixer on each other and now our head hurt bads and we have trouble doing the humans thinking and the whatnot sometimes. i think i have a xlr plug in my humans brain still and it feels hurt so get a doctor and his "special" tools to help you if you try it youself. the humans brain is too important to trust to your half-retarded brother and dads wal-mart tools so keep it in save haven. goodby

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.

My guess is 4 identical cardioid mics positioned in a circle... Panning: left - extreme left, forward - center, right - extreme right, back - center. To the front mic you add hipass filter or low shelf cut, to the back microphone you possibly add low pass filter or high shelf cut and phase inversion if nessecary.

or possibly just two omni mics positioned position side by side to represent ears and then panned to extreme left and extreme right = normal stereo microphone

http://en.wikipedia.org/wiki/Condenser_ ... r_patterns

if you have 2-4 mics and a way to record with them, you can always test this.

I really recommend this link, it clarifies a lot:

regarding binarual recordings.

The effect can be diminished or enhanced depending on your own head and your own set of ears. All of us can tell the distance and place something is according to what we know. That is our very own body.

To get a killer binaural plug is my holy grail, I've tried so many, including Panorama and none are as good as what I want.
