Letter to MR Jannard, 3D Sound Holophonics™, Opportunity for Red Digital Cinema.

[Martín Yernazian]

Hello Mr Jannard

I have been following the great success that your product has been producing for the past few months, is incredible what the camera can do.
First and for most thank you very much for opening the pallet of opportunities for us filmmakers
The Reason that I'm sending you this message is about the Argentine inventor Hugo Zuccarelli and his invention Holophonics™, a new native technique for 3d sound, working directly from the microphone you could create intense multidimensional sonic sequences right there on the spot ( on camera or external recorders), no mixing, no post production required, you can record mono( or what ever you desire) and you will have a sound that will make THX primitive.
I represent Mr Zucarelli here in the USA (California), and after commenting with him about the Red One, he suggested to show his inventions to you, since he is in the market right know to sell his patents (We have plans to offer it to Apple, Microsoft, Sony, Panasonic, etc), but we both feel that your product and your company stands in a more cutting edge position, a revolutionary progress that will open new ways for every creative mind, Exactly what we stand for.
Mr Zuccarelli not only has invented this new microphones, but also has the Loud Speakers™, a set of sound monitors with no distortion what so ever, that can emulate the 3D sound better than any monitor out there, and they are also directional.
As well a set of new headphones, that enhances the 3D experience.

I know that you are in the process of releasing the camera, and I didn't want to bother you until that was done, but again, I feel ( as well as Mr Zuccarelli), that your company will be the perfect home for Holophonics™, I mean, just imagine the power that you will be giving Filmmakers out there, a 4k camera with accessories that can make ( not emulate) 3D sound, that will be the cherry on top, and in my own personal opinion this is a huge opportunity for whoever acquires this Technology.
I hope my english wasn't a disaster, I will love to send you examples of Holophonics™, or have a meeting with you to demonstrate this technology. I know you will become obsessed with it, Pink Floyd, Paul McCartney, Steve Vai, and others were to.

Best Regards

ps: thanks for your time, and again, thanks for this great camera, I know that my technique Digital Cross Process™ will do wonders with it.

[Nathan Buxton]

Pink Floyd is not a person, and I highly doubt you could get their collective opinion on anything.

[chuck colburn]

But they did play with each other recently for the first time in 20 some years.
lol

[Martín Yernazian]

Dear Nathan, I think it is an obvious thing than Pink Floyd is not a person, but the worked as a group as chuck says, and if you need some credibility check for HUgo Zuccarelli's credit on the album "The Final Cut" were a lot of the recordings ( if not , all of them) were done in Holophonics
You should do a little bit of research before making any bold statements, that's one the things that forums like this one ( and Cinematography.com as Dvxuser.com) taught me

I will put some examples here, I know everybody will go crazy with this technique

My Very Best to all of You

[Graeme Nattress]

Martín, "The Final Cut" is 25 years old though....

As for the "no distortion what so ever" in the loudspeakers, I'd need to see the peer reviewed papaer in a science journal on that one. A statement like that is akin to perpetual motion.

Graeme

[Martín Yernazian]

Dear Graeme
Hugo Zuccarelli invented this technique in 1980, and he is been perfecting it all these years, working under his own name in the industry, it wasn't until recently that he decided to sell his patents and continue with his new inventions ( 3D motion images, 3D "IMAX like" googles, etc)

For the Speakers themselves, they were reviewed in science journals for the past years, I will put more information in the next couple of days, but the speakers were designed for 3D reproduction, and Zuccarelli was able to deliver an outstanding low level of distortion, from 2 to 250 feet with out any difference, ( my statement was a little bit off, you are right, but if this speakers made Michael Jackson and his producers cry because of the tremendous quality, then I feel I'm a little bit justify)

I will give more info in the next couple days as I say, I just got more to pass around, as well as tracks that you can hear.

Best Regards

PS: for all of you think of it this way: is like going from a B/W TV to a 4k projector, but in sound.

More to come

[Martín Yernazian]

The Holophonic Speakers™ are a revolutionary speaker system with never-before-heard fidelity that delivers a unique psycho-acoustic experience
which parallels live audio quality. The Holophonic Speakers™ are ideal from homes,churches, concert halls, auditoriums, and apartments.
The Holophonic Speakers™ produce a cylindrical sound wave that is uniform and homogeneous with its floor-to-ceiling configuration due to its unique mathematical properties.
The Holophonics Speakers are capable of delivering stereo sound evenly throughout an entire room, regardless of its size or the listener’s positioning
within it, thereby enlarging considerably the stereo ‘sweet-spot’.
A listener may stand anywhere within a range of between two inches to 250 feet from the speaker and still enjoy the same crystal clear quality of near-live sound. The unique cylindrical sound wave of the speakers allows
the listener to enjoy the volume of a concert without the damaging effects, with the speakers producing a sound pressure level that is relatively low-energy so that sound can be loud but without any discomfort to the eardrums.

The Holophonics™ Speakers feature a technology currently unheard of from any speaker, professional or consumer, out in the market today. In its floor-to ceiling configuration there is zero feedback when a microphone is in use - even at a range of 4 inches.
This breakthrough is the only technology that addresses and effectively diminishes the reverberation of the room with the use of extremely
large sound waves that automatically and mathematically interact with the room in a different way than smaller ricocheting sound waves.

By producing a cylindrical sound wave, the Holophonic Speakers™ produce very little audio bleed within the confinement of any room. This breakthrough
technology is perfect for large audio-venues with multiple rooms including movie theaters, concert halls, auditoriums, disco techs, etc...
The audio-breakthrough is accomplished by the Holophonic Speaker’s™ full-range, single membrane. A typical speaker set-up with a woofer-midrange tweeter multi-way speaker utilizes cross-over networks that introduce distortion by the separation of frequencies that are assigned
to the different kinds of drivers.
This is similar to CRT video projectors which separate blue, green and red rendering, and can only reproduce the image clearly to the viewer in one position of the room. On the other hand, in Holophonics Speakers™,a one-way, broadband membrane eliminates distortion associated
with separating and recombining the frequencies.

In sum, in the last thirty years the greatest advances in sound were accomplished by the digital revolution which provided customers with recordings that sound as good as the original masters, that were at the time, available only to the professionals.
Now, however, this revolutionary breakthrough speaker brings to the foreground a consumer product which provides the listener exceptional
qualities not yet available even to the most sophisticated professionals in the industry.

I think that should answer your questions, but if you gentlemen have more, We will be really happy to answer you.


Best Regards

ps: Graeme, this info is just about the speakers, and even do is great technology, the main plate comes with the Holophonics itself, thanks for your questions.

[Graeme Nattress]

If they're not zero distortion then, please don't say so as that kind of statements sets all kinds of alarm bells ringing. If they're low distortion, state the figure, or if you've got technical papers, preferably peer reviewed, I'd be very interested to read them.

Graeme

[Martín Yernazian]

Thanks, I will, it wasn't my intention to over blown my statement, it was my crazy English trying to be better and it came out wrong, also it is absurd for me to over blow the product since it speak for itself.


I will post as much as I can so you, Mr Jannard and all the Users at the forum could check it out

Best Regards

[Kevin Halverson]

Dear Mr. Yernazian,

I would be equally interested to learn how this 'technology' differers from say something like Ambisonics' soundfeild process developed by the late Michael Gerzon? If you, as the representative of Mr. Zuccarelli are going to be making fairly substantial claims (such as those posted here) your collective best interests would be better served by a bit less hype and a bit more science. I would recommend being especially careful and avoid the use of absolutes such as "no distortions". No or zero is as equally improbable as infinite and certainly makes me more than a bit curious when I read this type of claim.

I have been in the audio industry for nearly 30 years now and have heard every claim imaginable over this period. If this is truly new and revolutionary and can stand up to objective and subjective review, you will do well, but it is a serious industry and is not easily swayed by superlatives alone.

Has Mr. Zuccarelli published any papers on his technology in journals such as the AES? You mention patents that cover this technology, can you provide the patent filing number(s)?

I am heavily involved in high performance audio in my day job (in both manufacturing and on a number standards committees). If you would like to contact me off this board, I would be happy to review your information.

Kevin Halverson

[Martín Yernazian]

KhMuse, Thanks for your questions
As I said before, I apologize for that mistake, I undersantd that it wasn't right, point taken.
Now regarding the technology
as I said before I will provide more information to the forum in the next couple of days. And we would love for you to review our information, but I have to tell you that it has been reviewed and used a number of times in it's 27 years of history.

I will give more details in the next few days

My Best Regards

[Michael Hastings]

but I have to tell you that it has been reviewed and used a number of times in it's 27 years of history.

My Best Regards

It is statements like these that lead to skepticism. how is a 27 year old technology revolutionary? (vhs and betamax were fairly revolutionary 27 years ago.LOL) and if it is so great why isn't it everywhere by now? Surely many of the patents are expired?

[Kevin Halverson]

Can you site any of the reviews so that I might be able to do a bit of research? I have attended exhibitions and conferences related to audio in many different countries over the coarse of my career but so far, I don't recall running into this technology yet.

My curiosity has been peaked, please forward whatever additional information that you can offer.

Kevin Halverson

[Cail Young]

Sounds like exactly what the Bose Panaray and their newer funky PA stuff does. Yawn.

[Kevin Halverson]

Nothing wrong with a vertical line source (if long enough, it exhibits more uniform coverage over a given distance), though Bose has no claim to any innovation in this category. I certainly hope that this isn't the claim, as Shure and others have examples of similar technology that dates back decades.

Still waiting to receive some real information on "Holophonics".

[Kevin Halverson]

I did a quick google search and think that I now have located information on "Holophonics" technology. I located a few .mp3 sound samples that compare monophonic to stereophonic to "Holophnic(s)" sound. This is extremely similar to a number of processes that attempt to provide localization clues when listened to in a binaural configuration. The most recent similar approach that I am aware of is "QSound".

A quick listen to the samples from the "Holophonics" site and subsequent analysis of the signal characteristics reveal a very familiar L+1/(L-R) and R+1/(R-L) approach. I have seen this type of technique used in both binaural and conventional two channel loudspeaker playback. In the case of loudspeaker based playback what has been presented before is the addition of an additional high frequency transducer to each left and right speaker that is driven by the anti-phase high frequency energy from the opposite channel. This adds or exaggerates the left-right differential and is well suited to impulse types of signals (such as are exhibited in the samples from the "Holophonics" site).

For those interested in this, here are the relevant links to the sample files.

Mono: http://www.unoriginal.co.uk/Audio/Mono.mp3

Stereo: http://www.unoriginal.co.uk/Audio/Stereo.mp3

Holophonic: http://www.unoriginal.co.uk/Audio/Holophonic.mp3

There are dozens of different techniques, all presented by different entities that have attempted to gain market share based upon this or very similar processes.

QSound: http://www.qsound.com
VSS: http://www.surroundassociates.com

Frankly, in my opinion, these approaches all pale in compression to true surround process like Ambisionics and Soundfeild.

I invite Mr. Yernazian to provide any additional information that he can.

...no mixing, no post production required, you can record mono( or what ever you desire) and you will have a sound that will make THX primitive.

THX is a theater calibration standard that has more to do with architecture than electronics, and encompasses image projection as well as sound.

There are a lot of people in the film industry who find "mixing" and "post production" to be an important part of the artistic process.

Yeah, I do

[Martín Yernazian]

Gentelmen sorry about my absence, I will response your questions tonight

Pro Lost and Jeremy, no one is saying that we want to take those really important elements out of the process, that would be crazy and stupid from our part, instead what I was saying was that this will add a multidimensional element to teh whole process, it will benefit, not kill it, imagine instead of thinking up, down,left and right , it will been in a bubble surrounding you
with sound coming out of the back of your head, from feeling things crawling from the bottom of your feet traveling to the tip of your head, and that's just wearing normal headphones, imagine what a Sound Designer could do with that!!!

I will Putt examples tonight, I'm on a deadline with another project,
keep the benefit of the doubt, the same benefit some of you gave Red in the beginning, be patient you will be amazed, trust me I won't leave you hanging like that, and I won't make unsure claims, I will ask Hugo some of the questions that I don't have an answer

HI Kevin,

What do you think of Holophone?
I'm looking for a simple and easy way to record surround without having spend hours mixing it. Im looking into their Mini G4. It looked great at NAB this year.

[Richard Andrewski]

Yes, sounds like binaural miking. What I fail to see is what this has to do with the RED camera. Why would I want a binaural miking setup on my RED camera? The room noise you would pickup would be crazy. I did binaural miking experiments back in College in my dorm room. Yes it's cool but I wouldn't use it for movie making...

Also, anyone who's doing serious filmmaking is re-doing most of the sound in post. It's there that 3D audio and surround techniques would seem to make the most sense. But if I use a proprietary technique that requires special speaker setups then no one will be able to use my DVD products to their full extent.

What am I missing here?

[chuck colburn]

not much

[Martín Yernazian]

You are missing something,
You don't need any special speakers or sound output devices to perceive Holophonics, I use some normal Grado Sr 80, and the effect gives me chills.
I think people misunderstood me or I wrote something wrong, but If I as a filmmaker had the power of Holophonics on set, including my other sound gear, my production level will rise, and as filmmakers we are flexible, we could use it or stop using it.
I will go back to work, Tonight hopefully I could answer your questions and clear things up.

I still feel that this could be a huge asset in anyone's productions

Best Regards

[Ramesh Jai]

It's ironical that we have sceptics on this forum. I like your spirit and resolve Martin. Keep on it and I am sure you will prove your point.

[Kevin Halverson]

HI Kevin,

I don't know their prices so perhaps they are a good value, but compared to tetrahedron array (XYZ & W) this won't achieve anywhere near the same level of performance. The real advantage to a true soundfield process is that you can post process to any number of channels and with the true W (pressure) origin, you never have off axis playback errors.

One really interesting thing about a playback array based upon a soundfield recording is that the localization and relative orientation of all sounds work at any point within and even outside of the playback loudspeaker array. I have demonstrated a 6.0 playback system that has a LF, RF, LR & RR but has an added LSH and RSH (where the H component is height). This is an amazing listening experience (and there were a handful of commercial recordings made by Chesky Records based upon this concept).

An added advantage is that with only 4 channels (like the RED) you can record a true, infinitely decodable number of playback channels. Anywhere from 1 (monophonic) to any number of channels can accurately and repeatable be decoded. With a 4 channel delivery system, you can even let the playback end dictate the number and location of each playback loudspeaker with perfect reproduction of the original soundsphere.

With the four signals (XYZ & W) you can use a simple set of plugins to remix (in post) to your target footprint. No effort at all and you never have to worry about phase errors due to different arrival paths as the origin is a single point in three dimensional space.

If you want to learn more, I suggest reading up on the soundfield process or check with Calrec's distributor in your area.

[Mark Thorpe]

It's ironical that we have sceptics on this forum. I like your spirit and resolve Martin. Keep on it and I am sure you will prove your point. Most of the early RED Skeptics are now RED owners so go figure! Develop your dream Martin, if it bears fruit you'll be a winner.

When you hear it, your hair will go like this.

Seriously, Graeme is seriously into sound as he is into color, and I get the feeling that he likes stereo sound. I posted the link to a product that I thought was cool.
http://www.holophone.com/home.html
Graeme responded with a post that gave me the impression that he wasn't into the whole surround sound thing.

Speakers are the weak link in audio systems, so there is lots of room for new inventions.

[Mark Thorpe]

ROTFLMAO ........ I reckon there should be a 'Smiley' that seems to be pissing itself laughing.....man that would get used here!

[Graeme Nattress]

I'm not into listening to surround. Off axis sounds trigger the human fight or flight response and are therefore not relaxing.... (an efect used / abused by action / horror movies).

KHMuse, however, is correct about the soundfield recording techniques that use 4 mics in a tetrahedron. This encodes the entire soundfield and can be later decoded to whatever you want. To me, recording direct to 5.1 is not the way to go as you only need to record 4 channels to get the entire soundfield, so why would I record 6 and get less of the soundfield (missing height with 5.1)? Also, why would I lock myself direct into 5.1, again, rather than recording a complete picture of the soundfield that can be decoded to whatever you want?

And finally, recording the soundfield is a little like recording a movie with a 360 degree fish-eye taking in the entire scene around the camera. We don't shoot narrative drama like that as the whole point of a movie direction is to focus the viewers attention into seeing what the director intended - not to see everything.

Graeme

[Bruce Allen]

Martin, everyone's being polite to you, but you really need to stop posting using TM symbols and vapid PR and start producing solid results and documentation of your process instead.

I thought I wasn't going to comment on your post but after I gave the Red people such a hard time about their specs page, I thought I should chime in here just to be fair and say that your post sets of my BS alarm bells to an infinitely greater degree.

There are a lot of websites that repost shallow press releases. That's not really the vibe of this site, though. What's cool about Reduser is that the people who write here are really open about what they know and there is a wonderful sharing of knowledge.

I mean, Ty Ford posts here. Go to his site and you'll see a treasure trove of free audio info, sound samples, etc. I respect what he writes because I have learned a lot from him. You should do something similar if you want people to respect your pronouncements on your technology. Break down the current state of 3D sound recording techniques and technologies in an open and un-biased fashion, and explain how your process is superior in a specific use case.

Of course, I hope your product is super-cool and look forward to solid info, facts and samples! Good luck!

Yeah, the TM symbols have to go. Also, saying something made Michael Jackson cry doesn't prove much, I'm sure plenty of ten year old boys have done the same.

[Nathan Buxton]

'The Final Cut' is a Roger Waters album, not pink floyd ;)

[Graeme Nattress]

Well, indeed it is Roger Waters, but it still has "Pink Floyd" on the label.....

I see this thread has dried up - where's the info we were promised?

I offered to review anything that could be shared but never received any direct response.

I am afraid we might have scared him off. Too bad, it might have been interesting.

[Steve Sherrick]

I'm all for hearing about new technology both audio and video related. But I did get skeptical that his approach was to show up on this forum and present his case to Jim. Perhaps he just doesn't have Jim's contact info and this was the only way he knew how to present it, but if that is the case he needed to at least have all his info in place, ready to post links to papers and audio samples. He seemed a bit unprepared to me. He got my interest, just didn't follow it up with anything substantial.

[Jeremy Teman]

No.. Just saying.

[Graeme Nattress]

It wasn't just this forum he posted the message to, either!

i was too busy buying swampland in florida to see this one through.

[Mark Thorpe]

i was too busy buying swampland in florida to see this one through.Uhhhh, something you wanna tell us here? New secret HQ or.......?

[Martín Yernazian]

OK fellas, I apologize for the delay I been really busy working in my own projects, to contact MR Zuccarelli and their group.
At the same time I have been preparing a blog with sound clips and articles describing the technology, that's , honestly the best I could do.

I have to also make a point here, this was a letter to MR Jannard and his team, to try to set up a meeting between them and Zuccarelli to demonstrate the technology, showing everything in there, up and close and in person so any doubts will be full field, probably and more likely this wasn't the best place to send such letter.

I understand the skepticism, I one of them myself, but you have to understand that asking for the mathematical equation of this technology is ludacris to be post in a forum as open as this one. (or any off them) something like that is given to those that buy the technology and I don't even think it goes that far, if not how easily will be to steal it.

KHMUSE, we appreciate your interest in reviewing the material, but as HUgo have told me, the Technology has been reviewed plenty of times, and I will put some of the articles up as soon as I can so you can read them, the best I could do if you sent me your email I could send you a PDF file describing everything that I have propose here.
Some of you are right, I should have something ready to go before I posted here, on that matter I apologize for the delay or the wait.

Thanks Very much

ps: Graeme, I don't know what you tried to implied, but the honest truth was that when we sent this letter to MR Jannard and his team, we got an automated response, so we posted in 2 forums that we respect
Cinematography.com and REDuser.net.... thinking that Jim will read the letter and contact us so we can take 15 minutes of his time to demonstrate, that's all we need it.

Again guys in the next couple of days I will put a web address with a new blog made just to fulfill your doubts , Thanks again

[Graeme Nattress]

I am his team though (or part of it). Jim does not have time for everything that could come his way. Think of us as gatekeepers in that if we think it's interesting we'll tell Jim about it.

It's not ludicrous to ask for the math because if it's patented, then that math must be in the patent (as patents need full disclosure) and hence all you need to give us is the patent number. If it's not patented, then you should not be mentioning anything about it at all.

KHMuse is an audio professional. I have significant knowledge and understanding of audio issues, as do many other posters on this forum.

We're very interested to learn about your technology, you've just got to get us the information about what it is and we can take it from there.

Graeme

[Martín Yernazian]

Then that's clear, I will pass the information to the forum and more specially to you,
About the patent and the math, I think that's between Hugo and your team, I don't even know that info, as I said I will pass all the info I have in the next couple of days

[Graeme Nattress]

Thanks. That's appreciated.

[Eugene]

Graeme is right. Stereo is good enough.
http://www.thepowerplant.org/exhibitions/Summer_04_Janet/images/img_1.jpg
I saw an art exibit in Brasil. It was a surround sound art installation. They had a lot of speakers, and you know what? My ears/brain really couldn't tell which speaker the sound was coming from (more than right or left) unless I turned my head. And truning your head is something you don't want to do while watching a movie. And I really couldn't hear sounds coming from behind me. So, Graeme is right. Stereo sound is good enough. It took a lot of speakers and a trip to Brasil to prove to myself that I was wrong.

[Harmoniser]

Then that's clear, I will pass the information to the forum and more specially to you,
About the patent and the math, I think that's between Hugo and your team, I don't even know that info, as I said I will pass all the info I have in the next couple of days

To me it seems that "Holophonics" is basically binaural sound in a colorful package. I read that Zuccarelli claims it to be an audio equivalent to holography, recording the interference patterns between the incoming sound and an inaudible reference tone that the ear itself is supposed to emit.

However, after 27 years there still seems to be no theory or evidence for this. And Zuccarellis patents apparently only involves the construction of a recording head, not any of the so-called holographic recording technique.

The only sound samples I was able to get hold of were things like the matchbox, which sound, well binaural. As I understood it, the claim is that holophonics produce a quadrophonic kind of sound, but I could not hear any of that from the samples I heard.

Maybe you can present something that can convince us?

[Graeme Nattress]

And, of course, elsewhere on this forum we have the Tetramic, which uses four channels to accurately record an entire 3D soundfield, which can be decoded as any type of mic or micing arrangement in post. Ambisonics is real technology that's been around for ages and has fully proven itself.

Graeme

[Lexicon]

That Zuccarelli person has been trying to sell his stuff for almost 30 years. Looks like he's been sliced to pieces by the scientific community in various publications for his claims after he got some fame from having it used once or twice in the 80's. I guess he's achieved Legendary Quack status or something cause I can't find anyone who is using his "technology" apart from some secret stuff he is reputed to be developing and a claim that he's installed "special" systems at some South American venues.
