Is there an effect plugin capable of imitating holophony?

[Dana1]

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

It seems nobody does it well then.

The difference between holo and binaural is rather huge.

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

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

That won't give you any sense of up and down. You just described a glorified XY-pair.

holophonic sound is a class of it's own.

The Odeon project uses a combination of HRTF and Ray-tracing to produce it's realistic environments - 8K in pounds sterling to you, sir.
Closest plugin to this is QuikQuaks Rayspace, though a combination of HRTF and true stereo convolution reverb (for the room) might get you near the room/sound you want.

old thread, yes, but i've been looking around for stuff like this... it seems there's no VST/AU plug-in that provides both HRTF & acoustic room modeling together. Wave Arts' Panorama 5 has basic simulation of a room, but it lacks frequency attenuation features and the room is a simple cube shape.it doesn't suck, but it's really not what i want.

RaySpace, on the other hand, has the ability to trace a very complex environment, attenuate frequencies, and define other spacial modeling functions, but does NOT have HRTF in the "listener" portion. it's a damn shame. a year ago i had emailed QuikQuak about whether they'd be supporting binaural features but never got a response. maybe i should ask again and specify "will you add HRTF to the listener" or something...

anyone found anything new since this thread's original date?

• -Odeon is impossibly expensive and isn't a plugin.
  -RaySpace lacks HRTF (if it had it, i would probably have what i want).
  -Panorama lacks realistic acoustic modeling of the space (if it ray-traced, like RaySpace, it would be right).
  -Convolution Reverbs are static reproductions (can't change positions/materials/room).
  -Logic's Binaural Panner doesn't model acoustic environments. it positions around the head only.

Is there anything else??

It seems there's no tool to combine HRTF location AND realistic acoustic space. It's either HRTF OR reverb, not both. adding one plugin to the other, no matter which order, wont accomplish the task of getting HRTF & environment with accurate binaural qualities. if you put an HRTF panner after a reverb, for example, the reverberation will be localized. if you put reverb after HRTF panning, you eliminate the localization/panning.

oops, my bad. Panorama DOES allow you to define the materials of the walls in the space simulation. the controls are kinda hidden, but reading the manual helps. still... it's not ray-traced and the environment is still a simple cube. RaySpace allows you to move a sound source down an adjacent hall on the left of the listener, for example, which Panorama can't.

The IRCAM Spat plugin might also prove useful in these situations

oh, yes, i forgot to mention that one. it does offer some nice filtering on distance changes that are lacking in Panorama. it also has a much better (zooming!) panning control area (compared to Panorama).

i tried the demo but didn't care for a few things: dongle, reverb is just tacked on, instead of being modeling or even simulation of a real environment... and it's very expensive for what it does (glorified panner with glorified reverb... it's just not that unique, though it IS well made).

it's a nice, smooth panner and reverb but it still isn't a unified HRTF+acoustic space. tacking reverb on after HRTF kind of defeats the point of HRTF spacialization. the acoustic reflections in a space are a vital ingredient on localizing sounds in an environment.

[Jace-BeOS]

Panorama is so far the best one i've tried, but, as i said, the room simulation is poor. and, no matter which HRTF models i choose in its available collection, the sound still feels inside my head. i've played with all kinds of different settings and it just sound like a "better, more flexible panner" than normal ones... not BINAURAL.

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.

My invention is to wear headphones while riding on this:



Though you'll end up with very twisted headphone wires...

I have not read the whole thread so sorry if it has been mentioned already or is inappropriate but I just stumbled over this recently and wanted to mention:

(currently only for Nebula but a VST plugin is coming).

I'm in no way associated with it.

The psychic tv album dreams less sweet was recorded using holophonic techniques (according to the back of the record)

[manvanmars]

I have used this plugin for positioning with some succes a while ago:

More information about this technology here:

Also can recommend running a phaser into a reverb(mostly using plate for this but probably anything will do here...).

it was amazing. Those guys voices are so funny and the effect of the guitar (left far side) sounded so real I thought someone is in my room.


This would be awesome to apply in music. (VST)

yeah it's super expensive. the free lite version lacks 3D spacialization which makes it kinda pointless....
