  • The Hear Holoplot X1 Demo video showcases the Hollow Plot system, an innovative audio technology that uses a multitude of drivers to create various effects, such as wavefront synthesis, beam steering, and coverage control. The system features a variety of speakers that can be arranged vertically, horizontally, or in both directions. The video presents a demo of the Holoplot X1, an advanced audio technology capable of creating a surround sound experience through the use of reflection and virtual sources, as well as challenges associated with using this technology, including the time delay for sound travel and the need for high resolution and efficiency.

    Back in the 80's I read some Speakerlab documentation that showed an old experiment where there was a very large array of microphones - think 20 feet by 50ft - behind an orchestra in a symphony hall. They recorded the orchestra and then played the recording back through speakers that were colocated in the same position as the microphones. The audience could not tell the difference between the live orchestra and the recording. Everything old is new again.

      Interesting and kind of cool and this is something that was not really possible until processing and amplifier size and power outputs could be optimized.
      Just the amount of signals sent to each speaker cabinet is astronomical and the amount of data and processing is astronomical and keeping the heat generation down from the amplifiers are all substantial challenges

      This is the real way forward. All other systems are now as invalid as a Victrola (which I enjoy listening to as I have no choice but to listen to the music since there is no such thing as fidelity or holographic imaging) (-:

    • @DaveRat
      @DaveRat  Před 8 měsíci +1

      It could be interesting, Atmos is focused on recreating an environment inside of your listening environment, this system is focused on recreating the actual musicians in your listening environment, kind of different concepts.

      That’s Harvey fletcher’s curtain of microphones and curtain of speakers. Adamson fletcher machine follows these principals in its engine.

    • @DaveRat
      @DaveRat  Před 7 měsíci +4

      That microphone curtain concept won't work and it's flawed.
      The simplistic concept of grabbing sound from various spots and then re-radiating it loses all of the directional and vector information of the original signals hitting the mics and replaces it with the dispersion of each individual speaker which is completely unrelated to the arrival vector of the sound on the microphone.
      To make that work they would need to do something like have each microphone be three or four microphones they grab not only the sound arriving but also the direction from which arrives from.
      Then each re-radiating speaker would also be a cluster that recreates not only the sound picked up by the mic but radiates it in the correct direction that the original signal arrived at.
      Only then would this system begin to function without blurring things into a mess

  • @Alkatross
    @Alkatross Před 8 měsíci +7

    You know what i like about this video? Dave walks outside the defined listening areas so we can hear the effect breaking down. Such as the big null point right in front of the speaker during wavefront playing. Or the delay scattering when they bounce off the rear. I came away with a workable understanding of how they acheive the effects. That is a huge amout of channels and processing. I wonder if they send all audio and control data wirelessly to the units.

    A simple idea, have two concerts in the same venue at the same time. The experience of dancing and jamming out to one band while half the audience is enjoying a totally different style would be surreal. Of course you would need all electronic instruments and in ear monitors to keep the stage volume very low.

    This is same theory used for AESA Array Antennas 😃👍. The price tag make sense. Each individual component require a discrete amp, phase alignment and signal conditioning. Thankfully to advanced class D amps in a small form factor and high efficiency in dsp processing this is now possible. I think this will revolutionize the profesional audio market. Do you imagine this system in a live concert with the integration of SPAT Revolution: Flux Immersive a real time spatial environment?. This will be mind blowing. I look forward for more content related to this topic 😉👍.

    • @stingber
      @stingber Před 8 měsíci

      Spat Revolution from Flux Audio allows you to enable Wave Field Synthesis (WFS) using a long row of speakers. It kind sounds like a Home TV sound bar right? But in this case, the beam is not steered is only one wide beam covering (wide even distributed coverage) the audience.

      @DaveRat  Před 8 měsíci +4

      Great question. In my opinion they sound pretty good. Not as good for pure music as conventional point source and line array designs. But they do sound pretty good, clear and have relatively powerful output.
      And pretty much like how the whole universe works, The more processing and party tricks you try and do the more sonic hits it takes.
      I have not mixed a live artist on it, and only heard it with played back music and my experience is that many systems can sound good for music playback but are challenged by live music.
      Reports from the sphere trend to focus on the party trick aspect more than the actual fidelity.
      It will be super interesting to see where the systems end up and if they catch on

    Holoplot is very impressive stuff... But you know what's even more impressive?
    The Yamaha YSP-1 soundbar. Released in 2004, almost 20 years ago.

    • @FOHFILMS
      @FOHFILMS Před 8 měsíci

      The YSP-1 was a soundbar that featured 42 digital amplifiers, 42 DSP channels and 42 speaker drivers and was able to provide discrete 5.1 audio from a single array of drivers through multiple beams formed and reflected off of walls at the desired virtual speaker locations. Essentially the same as the "different audio sources for different areas of coverage" demo here.
      It also featured wavefield synthesis, mainly in the form of being able to adjust the center channel image's depth.
      The craziest feature? The remote control had a *built in microphone* that, when the "my beam" function was used, would send out a few pulses from the array and send the microphone's captured information OVER THE FREAKING IR BLASTER back to the main unit to compute a very precise, tight, singular mono sound beam aimed right at where the remote was being held... designed for personal/quiet listening.
      In 2004. Crazy.

    • @DaveRat
      @DaveRat  Před 8 měsíci +1

      If an amp is damaged by back EMF from the dual voice coil that would be almost the same as an amp being damaged by damping factor by sending a pulse to a speaker and having the rebound energy damage the amp.
      So in my opinion the answer is, if a double voice coil damages the amp you don't want that amp and it deserves to be damaged anyways.
      It does bring up an interesting aspect in that if something is panned hard to one side and one voice cause working The damping factor of the amp would put the brakes or slow down the other voice coil from moving so there will be some interaction not necessarily damaging to the amp but the signal could be affected

      Sound wise doubtful there is a diff that is audible. But, oxy free copper is more pretty and tends to be easier to solder.

    • @DaveRat
      @DaveRat  Před 8 měsíci +1

      Low frequencies are messy and even with extreme control over where sound goes, lows and subs which are the primary issue which sound complaints, are not focusable without arrays that are significant in size relative to their wavelength.
      Think arrays that are like 100 feet wide and high.
      And even then, focusing sound is part of the battle, the reflected sounds will still be a big concern

    This is might be cool for presentations and 3D, 4D, 5D… shows… But in live music it’s just doesn’t sound right especially in a very high frequencies 5K and above… these drivers are not close enough to each other to get good summation on that range, so if you will play same signal from all of these drivers at the same time it will give you lots of interference in a very high frequencies. Also how they can throw sound for long distance without any waveguide or any horn?…
    I went to U2 show and was able to walk around and listen, so it’s doesn’t sound as good as you expect from this new technology…. The all mid range sounds good and focused, but low end is muddy and not focused and there’s no high frequencies at all I mean there’s nothing from 4-5k and above and I think that they reduce that for a reason.

      I agree with all of that except for the need of a horn or waveguide to throw.
      Sound is an energy. Wave guides and horns don't create throw. They just reduce the dispersion so that more of the energy is focused in a certain direction and possibly make the speaker a bit louder by increasing the coupling efficiency
      Having a whole bunch of tiny little sources all recreating the same sound is almost the same or the same as one big source creating the sound.
      Very loud and focused long throw sounds can be created by multitudes of small drivers just the same as a singular large driver

      @DaveRat  Před 13 dny

      Yeah I guess they can definitely recreate a multi-source sound system and there are multiple sources in a surround sound configuration. There are other surround sound algorithms maybe look at L-Acoustics L-Isa which would probably be more appropriate for live sound

      @DaveRat so is beam steering the same as dolby atmos?

    • @DaveRat
      @DaveRat  Před 13 dny

      No it is not. To the best of my understanding, Atmos is a multi-point object-based system we're multiple sound sources can be sent to multiple speakers at varying levels to create an immersive experience.
      Beam steering is where you have an array of speakers all working together has a single complex speaker and by altering time and phase of the signal sent to those various speakers in the array you are able to point the sound in various directions.
      Kobe Atmos is like a field full of sprinklers where you can turn on and off various sprinklers at different levels
      Beam steering is like holding a hose and shooting it in various directions and having control over the width and distance of the spray

    I would like to see modern point source rigs that can cover arenas with modern tech applied to remove the issues we had when we couldn’t get the HF drivers close enough to avoid combing in the horizontal and vertical, the way modern line array systems do this in the vertical. There is something to be said for physical size when you want to control the largest wavelengths. How about a co-entrant rat trap that puts the HF drivers virtually several feet behind the boxes where all the HF drivers in the system virtually originate from the same point in space, and the entire front of the cabinet is the horn opening, with Dave’s “Focusing” applied to get rid of the internal reflections? Of course the grills have to have tiny LEDs on them so the people in charge of what is seen will allow it. If each box covers its own area, then the only steering needed is to match the shading, but I bet you can get close with tighter patterns for the longer distances. How fast can we load it in and out? Hey, I’m just an idea man. I’ll leave it up to you to figure out how to do it Dave.

    • @DaveRat
      @DaveRat  Před 8 měsíci

      I would like to see that as well but it doesn't seem to exist at this point. Using increasingly directional horns to cover far away places and try and maintain volume consistency can work but gets large or more specifically makes the cabinets very deep and different in size. This makes traveling with them and versatile array configurations quite challenging.
      Additionally even when the volume over distance issue and coverage issues are resolved and minimize overlap interference issues using multiple point sources, The problem still remains of keeping sound off the roof and tight vertical coverage control.
      Lionaires do this fairly easily and with great accuracy and point source arrays have very little or no control over it unless line array type configurations are used.
      So you can see the quandary here, point sources tender work better when configured his line arrays.
      I think this is why there are no major tours traveling with point source systems at this point in time to the best of my knowledge.
      If you can find a band or artist traveling with a point source array doing arenas or larger please let me know because that would be very interesting
      Point choices are great they just don't scale well to large format audio coverage and transportation

      @@DaveRat I want line arrays in both directions. I prefer the low frequency control you get with size more than the low frequency control you get with steering. I’ve played with most of it. Steering and smearing has its place. The manufacturers fought against the line array as the end all be all solution for a long time, rightly so, until they realized they could sell 10x as many boxes and ultimately that is what they care about most. Ultimately the challenge I think is in packaging it, then after that selling it. Turbosound seemed like they were getting there with the aspect but that wasn’t a large scalable solution. If we could have a line array that did a solid 180 degree pattern lows to highs, and we could just use the vertical angles to get more, further, that could reduce the number of hangs needed for horizontal coverage and reduce that horizontal combing. I haven’t seen anything that can do that yet. (have you?) There would need to be stearing drivers in the box to get the low mids and lows to behave.

    • @DaveRat
      @DaveRat  Před 8 měsíci

      @tigeraudio interesting. My take is it the sound vendors and sound engineers are what pushed line arrays to the level they are now. Has a sound vendor having a point source system would be a nightmare. Having a line array that allows us to easily alter the coverage and use a single box size is absolutely genius. Add in the fact that we have control over volume versus distance and the fidelity is maintained and it's a huge win. Rock concert sound in order a magnitude better than they ever have and were able to cover longer distances with less gear and better coverage than ever. Much of this is due to the development and deployment of line arrays.
      Looking at it the other way, if point sources were so good how come nobody tours with them?
      I heard the aspect and the big issue is whenever you have side by side sources, The precision of our hearing in the horizontal domain divulges all of the problems. Also horizontal arrays have no control over the vertical and any indoor venue with a ceiling is compromised by not keeping the sound off of the ceiling.
      Yes there can be other solutions using point sources but they're all cumbersome and a huge bummer to deploy
      Hold on let me bring the whole PA down and switch out box number four with it 12° instead of 14° dispersion horn so we can get this point source system covering properly.
      Or let's change the angle between box number three and four and five oh and we're all good

      @@DaveRat Yes, the end user definitely pushed for it. I recall Scovi really adopting VDOSC early on. Before that I only remember Yanni having it. What I mean is not to have horizontal instead of vertical but to have both at once. Logistically the horse is out of the barn, but the low end was well controlled in those huge point source rigs. The issues you refer to in the horrizontal and our ears are very substantial with line arrays 15-20feet apart. The coherance (inteligibility) suffers. Of course in that tiny line where they are equal time, there is no combing, but our heads aren’t quite small enough. Everywhere else where they overlap, its messy. What they are doing in the vertical, I also want in the horizontal, not one or the other, both. I don’t think we need to worry as much about the interbox angles in the horizontal if we can get the vertical the way we want. The trick will be physically being able to do it and rig it. We went to the moon though. I have not heard the aspect. Not all that eh?
      Why don’t people tour with big point source rigs? None exist that can do what we want, and money. At least initially line arrays were cost effective. Now, I’m not so sure.
      One of the manufacturer’s that pushed back heavily was Meyer, and I heard from one of the staff sales reps, John Meyer wasn’t interested at all in going down that road but once they talked him into it, they sold enough Milo to buy the company that made the Galileo etc, and he could afford to hire more scientist, etc. Again, it comes back to money, like everything else. Its always money. I have heard a lot of point source rigs in arenas that sounded fantastic though. The Nexo Alpha I was flying was extremely fast up and down. The 6 wide 4 deep rig (in the air) was only covering lower bowls. WOuld have had to double it for the entire hieght of most of the arenas. We had the audio truck loaded with backline, monitors, PA, etc in 48 minutes on the worst day. The day we had a ramp load but used house PA, it was 28 minutes. Not too bad. That is from downbeat of walk out music. We also didn’t carry video anything on those tours, so nothing in the way of getting in and out. I liked your side by side rig. You solved the problem of not enough line to get enough power. I am not anti line array though. I just don’t think that’s the end. We were there before, came back to it, but its time to move forward and revisit PS systems and bring back to it everything we have learned in the last 25 years. Personally, I would be happy to mix in clubs and theaters the rest of my. I find the bigger shows to lack intamacy. If you NEED imag, its too big, but a lot of visuals go to shows. We have to drive 3 hours here for most. I wish they did more, smaller stops rather than fewer large stops. I am happy with a good band, enough light to see them, and a great sounding PA. Don’t need any other “show” if the music is great. I drove through 4 states to see a band in a small cap club on tour break over the Summer. It was a line array. XSL. LOL. No joke, I was thinking it would be great if it was the same massive stacked PA I saw them on 25-30 years ago. It definitely wasn’t the same experience, but then I wasn’t up front headbanging either.

      @tigeraudio we had a nexo rig and briefly an aspect as well. Coverage bummer. Nexo, do you line or checkerboard the nexo? They both had significant issues.
      The EAW 960 rig, Meyer msl10, and that cluge of open back fiberglass and aluminum framed boxes from JBL we're all failed attempts at doing large format point source.
      Vertical line arrays are challenged in the vertical while pure and pristine in the horizontal.
      True single box point source is pure and pristine in both vert and horizontal.
      Combining vertical and horizontal into a grid or T or + or any other non 2 dimensional shape creates challenges in coverage and sound in both the vertical and horizontal
      That said, developments in that direction are being addressed by systems like Holoplot
      Going from point to line, is complex, as we see with computer modeling, precise angles and such. From line to grid is an order of magnitude more complex or just a huge diminish in sound quality and coverage, take your pick
