Holophonic Sound is produced by recording the interference pattern generated when the original recorded signal is combined with an inaudible digital reference signal." (source) That's interesting. And leaves me with more questions than answers. What's unfortunate is that they speak of the quality, but this sounds kinda cruddy to me: Sound Ideas Dimension Sound Effects Library I've heard better from other methods. But let's keep researching anyway, shall we. "Zuccarelli believes the ear/ brain generates its own reference beam. Using a technique analogous to the laser beam in holograms external sounds are recorded with synthesized reference sounds. The brain provides its own second reference beam and "decodes" the holophonic record reproducing the original ambient conditions." (source) Yay, ITOTD did a piece on it: Holophonic Sound: Interesting Thing of the Day "His holophonic process starts with a type of binaural dummy head, but it reportedly records the interference pattern formed by mixing the sound with an inaudible, digitally superimposed reference signal." That sounds heartening. Gives the impression that we might someday be able to get bespoke pinnae reflection recordings, and apply them in real-time with plugins for Winamp/Foobar/iTunes. Surely it's not that easy, but it should give an extra push towards realism. How similar is this to the HRTF plugins that already exist, though? Do they just not get enough love because most people don't have worthy headphones? Hah, gotta love what's tucked in the corners of places we've already been to: What is Holophonic Sound, Where is Hugo Zuccarelli? - The Binaural Source Unfortunately, he links to theaudio.com, saying that they have the holophonic heads -- but when looking through their site, they only offer a spherical binaural mic and don't mention a damned thing about holophonics. Missing the point, gents. [size=medium]Oh hey[/size], a spooky experimental album from 1983, recorded with Zuccarelli's methods. The Thing On The Doorstep: Psychic TV - Dreams Less Sweet I'm gonna go listen to that. Maybe I'll peek under some more internet rocks later. |

Even if they say their head-related transfer functions are "more than that" - it's just more advanced HRTF. Honestly think about it. The only possible way you can locate a sound is by comparing the time at which the same sound arrives at each ear. You don't think about it, it's automatic. Any possible cue for position has something to do with the way the sound bounces off or flows through your head. It's hard to simulate because there are so many factors. The shape of your outer ear even makes a big impact. |

The holophonic recordings work great on them and I can pinpoint the location of the sound. I'm looking to create recordings like this that anyone can listen to, so it's important that it doesn't require any special headphones. That does seem to be the case. It also seems that Hugo Zuccarelli's holophonic sound might be different from Stakey's Cetera algorithm, as Hugo invented his technique in the 80's and Cetera didn't come out until '99. Eitherway, the effect seems to be the same. Hard to know which one you're listening too though, as even the Cetera recording is found on the web as Holophonic. So with the confusion of the differences between Holophonic, Cetera, and Binaural who knows which method the recording they're listening to is made from. Cetera would definitely work though, since I know the Virtual Barbershop uses Cetera. Buying mics for my ears is what I planned on doing, but I wanted more info first to see if it could create recordings like the ones I posted. I'm making a few contacts to find more. Yep, those are some of the pages I've found. I was hoping someone here knew exactly how to do it, or if there was software or hardware to create the emitted sound or make the recording, etc. I didn't find any actual products though, just the Holophone, Binaural mics, dummy head forms, and other 3d sound recorders. Perhaps there's a recording forum I could ask on. I also found a page with Hugo's email. So hopefully it is up to date and I can shoot some questions to him. |
