Holophony (a.k.a. holo-sound) is a technique to capture the position of a sound source - including top-bottom and front-rear - and it can be listened to with normal stereo headphones.

To listen to some examples, go to this webpage, click on the "TEST holo-sound" text (left-top of the page). A small window will popup. In that popup window, I suggest to listen to (in sequence) "Cerini stereo" and "Cerini holophonia" (they are mp3 files), with your headphones on. It's impressive! blink.gif Other examples are reported below in the same popup window.

There are a number of processing methods used for things like this. The best ones tend to use well-established HRTF [head-related transform functions if I'm not mistaken].

My favourite system for multichannel sound, though I have never even had the opportunity to hear it on a real system, is Ambisonics [which has been around since the late 60s/early 70s].

For the most part, for headphone listening, I prefer simple binaural recordings, though.

Hmm, it's fairly convincing to me, at least with the V6s. But it's more of a stereo separation with a bit of "Z-axis action" (height) than anything else. There isn't all that smooth Left to Right transition and very little depth in the sample I tried. Neat trick nonetheless.

Unsurprisingly (or not), it sounds very flat if you're using any sort of spatialzation routine with your speakers or headphones vs. normal "flat" stereo when playing back said files.

In a strange and related note, using VPF (Studio) settings on one of my cans with very little soundstage imaging really helps the final result. So much so that I can literally imagine where the singer is, where each instruments are and such...
