I'm going to try to calmly go through this by the numbers. If anyone ever reads this, I'll be surprised... but let's do this. 1. In-ceiling or ON-ceiling (or even on-wall) is irrelevant. The only issue with in-ceilings is with the ones that point straight down. At the Dolby spec'd 45 and 135 angles, most in-ceilings that aim straight down will have such poor off-axis response that it isn't ideal. BUT many in-ceilings now have either angled baffles so they point toward the MLP (making them functionally the same as a speaker mounted ON the ceiling) or at least aimable tweeters so you get the directional part of the sound aimed toward the seats. Those most directional frequencies are what matters most for cross-channel imaging. 2, The physical speaker boundary in the home is NOT supposed to line up with the orthogonal mixing interface, but with where speakers would be in a much taller space like a movie theater. What matters is THE ANGLES. We hear in terms of azimuth above us, so what is important is our ability to hear amplitude-based steering in certain regions of the room. The interface is an abstraction layer to make it easier to visualize general placement in a room. Now, in theatrical processors, the data gets adapted to the space by way of the initial setup making you input the room dimensions and the locations of every individual speaker in that room. If the home version relied on that, it would have been a bit outside of what your "average user" would understand (though us enthusiasts would love it - and Trinnovs implement some of this). 3. Research shows that we have a pretty good ability to hear between speakers on the vertical up until just over 45 degrees. Where imaging between two speakers falls off is as you hit about 60 degrees of separation (whereas 60 degrees of separation in front of us for stereo is great), at which point people surveyed were unable to accurately place sounds steered to the upper speaker consistently. The reason this is important is this: Yes, when you place speakers at your room boundaries closer to the 30 degrees of the front/rear height designation, you are making that interface match your speaker boundary in your smaller room. You're ALSO leaving a 120 degree angular gap. Contrary to what you say in the video, this actually makes it WAY harder for sounds to image above the listener. In a top front/rear configuration, you would only have about 90 degrees of separation above the listener... which inherently works better for placement above the listener. Static placements won't be precise, but they don't need to be... because research also shows that our perception of spatial resolution above us isn't that great. However, our ability to perceive pans across these speaker locations tends to work pretty well regardless. 4. The areas of the room that you show with a red X do not get "no coverage". Because we hear in terms of azimuth, those regions of the room get imaging between the two layers for sounds NOT at max Z in the interface. So for example, if an object in front of you directly between two adjacent speakers on the vertical was at say 0.75 on the Z axis, this means roughly that 75% of that sound will be in the corresponding height... but that 25% would be in the ear-level channel. So with two speakers with 45 degrees of angular separation, you would hear that sound at about 33 degrees... or basically where your front room boundary is (or where that green circle is at 5:50ish in the video). In the case of your Atmos file, as your voice moves upward, it cleanly pans from my left main to my top front left speaker. Now, does the sound appear to be closer to me once it stops at max Z? Yes, because... 5. Precedence. The fundamental truth is that a speaker closer to the listener will inherently sound closer to the listener. This is why in a perfect world, we would have a layout where the distance from us to every speaker is exactly identical. But none of us live in that perfect world, which is why our AVRs have distance/delay settings. This makes it so that sounds from speakers at varying distances will all arrive at the MLP at the same time. So as sounds move from speaker to speaker, these delays ensure that those pans move to the right degree for the intended placement. They also help lock imaging between speakers. BUT although this works great as sounds move between speakers, when a sound is firmly planted in a speaker that is physically closer to the listener, your brain still goes "That's coming from that speaker there." whereas sounds imaged between multiple speakers tend to kinda' image THROUGH their physical plane more generally. 6. The quality of your AVR/Pre-pro will not affect where you perceive a sound to be with top front/rear nor will the quality of its room correction. That speaker's imaging BETWEEN speakers will be affected by equalization (because you actually need those high directional frequencies to image well between speakers), but a sound from an individual speaker will sound like it is coming from the direction of that speaker. Now what CAN affect this is something like Trinnov's re-mapping, which can alter how all of this stuff gets steered... but that is a whole other conversation. 7. At 7 minutes, you ask how in-ceiling speakers will image a sound right above your head. Actually, they will image a sound there FAR BETTER than front/rear heights will. Why? Because they're phantom imaging between 4 speakers with 90 degrees of angular separation. Speakers at 45 degrees of elevation, too, which will already inherently sound more "above" the listener than those at 30. If they're pointed down, you still get the imaging there... IF you've equalized to account for their off-axis response. With angled in-ceilings, it would be no different than if you had speakers mounted on the ceiling (like my Prime Elevations), because the directional frequencies are aimed toward the seats. It can't "image it a little bit lower" or higher because at that point, it is just imaging IN TERMS OF AZIMUTH. You are hearing that direction, not a coherent point source. What COULD image it a little bit lower is if the object was brought down from max Z and the side surrounds started to get some bleed of the sound... but that kind of in-room placement doesn't resolve as well. 8. At 7:34, you say that if you have front/rear height, they will "for sure be able to image that sound without issue." This is exactly the opposite of how imaging works between speakers. You will never get better phantom imaging between two speakers with equal amplitude at 120 degrees of separation than you would at 90 (and the lower the angular separation gets, the more coherent the imaging between them, up to a point). This problem is exactly why Auro in the theater uses a VOG speaker - because that's where the inherent weakness is in imaging in their layout (though VOG in the home doesn't work quite as well, because... see Precedence). You are effectively trading imaging overhead for more compressed imaging from ear to height. Front/rear height objectively, absolutely makes it MORE difficult to image sounds precisely above the listener. How much does that matter? It depends... because remember, that region of hearing around us is where we lack spatial resolution anyway. 9. You're not missing anything with a top front/rear placement. Because of the separation angles and how our hearing works with elevation (which I had a long fun discussion with Joe about recently that I won't rehash here because it was nerd-level talk about AES papers), you're actually gaining precision - not just in the region directly above the listener, but in the areas about half-way between your ear-level and height speakers. To summarize what we discussed, front/rear height gets you about 15 degrees of precision for elevation above ear level, whereas top front/rear (whether in or on-ceiling) gets you about 23, with the regions below that being spatially imprecise with steering anyway. That part is, in my opinion, MORE important for good Atmos than just the "directly above the listener" content. And I say that having done every possible layout one can do for 7.1.4, upfirers included. 10. So what does all this mean? It means that the disconnect you speak of isn't that the orthogonal interface doesn't match up with the boundaries of a smaller home space, because it isn't supposed to. The disconnect is that the Atmos mixing interface is, at a foundational level, just a perceptual room-based interface for what is ultimately still vector-based amplitude panning with an additional aspect that attempts in-room placement. And once you wrap your head around it, you'll understand that what is most important is maintaining angular separation between speakers in each region of the room such that amplitude panning is still stable between each adjacent speaker. It's why Dolby's mix room guidelines are for 7.1.4 with top front/rear placement. That is literally the minimum layout being used for all home mixes. Everything above that is to add precision in larger spaces or coverage for more listeners. Thank you for attending my TED talk. If you made it this far, comment "Channa's shirt is dope." 😃

Maybe you and Home Theater Guru's can be on with Channa and me because you both seem to mostly agree. And I also think I understand the concept of the angular separation. Perhaps we can make this a long-form discussion. We could set something like that up. It would be interested, and I'm open to learning and sharing my findings. I think we can come to a better understanding that way. Somehow, I think we're saying very similar things, but in different ways. I also think that we prioritize different aspects of the sound with regard to precision and panning. In audio, we are always working with compromise. Do you want better panning of sounds overhead, or do you want more cohesion with the ear-level speakers? That's a compromise. We have to be specific about how different layouts improve the sound in one way, while degrading the experience in another way.

Channa's shirt is dope! I agree wholeheartedly with Atmos 7.1.4 speaker placement being based on azimuth angles between all of the 11 speakers to give a more precise placement of a sound object anywhere in the 3D room. Visualize a smooth pan from front height to rear height - if the angle between the front height and rear height speakers is too great, the pan between them will "jump" front to back as opposed to a gradiant transition as the pan was mixed. I think using a protractor and measuring tape is the best way to place your speakers as the Dolby Atmos spec was engineered for on a good mix, and the front/rear height settings on AVRs is only for those who won't or can't put holes in their ceilings and are willing to settle for a compromise, like using Atmos sound bars or up-firing Atmos enabled speakers. As always, your mileage may vary.

7.1.4 here and it’s all making sense with every video you put out , height speakers in my system. Keep Up the great work in making more enthusiasts aware .. cheers

Thanks for this project. After watching a bunch of your videos, and a bunch from your peers, I got the confidence to overcome the limitation my concrete ceiling produced and went for 2 heights on wall up front, above my FL and FR, about 3 inches below the ceiling and 2 in the rear, at the same height, about 4 feet behind my SL and SR. I played around with a lot of official Atmos demo content and found it cool but nothing placed the sound exactly as intended like your video did. Until your full video, I was concerned about not being able to image sound above my head but when you move it across the top and to the middle, I swear it sounded exactly like a speaker had moved across my ceiling right to the top of my head. I have a 5.2.4 setup now. An Anthem MRX 1120 running PSB Image T6 x2 , XC, XB x2 with a level matched Paradigm Cinema Sub and SVS PB1000 with 4 SVS Prime Elevations up top. I'm wondering if I would have even more benefit from throwing 2 more up top, 45 degrees ahead of me (contractor buddy pitched a tray ceiling attached to my concrete ceiling idea and I'm considering it). Considering how I could trace your sound almost perfectly with my eyes closed as it moves around and above me, in my space, 16x16', I wonder if it'll add anything worthwhile or not but then again, it shouldn't diminish what I already have, right? Thanks for your great content, friend.

Thanks so much for this video! Just last week I purchased a Denon 6700h, with intentions of Atmos. I have 7.1 bed layer of def techs and wanted the Atmos experience. Everyone said ceiling or upward firing. I had 4 extra pro monitor 1000's, so I decided to follow the Auro 3d set up. Two above my mains, and two above my back surrounds. All I can say is wow! My front stage sounds like I have towers.I have Demand d11's as my mains and 4 d9's as surrounds, the 1000's compliment them perfectly. When best buy installer came, he said that this was wrong, but he did it as I requested. After we calibrated, he was amazed, he said that he had no idea, but was impressed. He had no idea about Auro 3d. Thank you again for helping me make this right decision.

Awesome video. Thank you. I having been looking for a test video like this for a while in order to test out my system. Was able to test on my system via Plex using Roku. Speaker setup is 5.1.4 with in ceiling speakers being front heights and centers. Rear channels are mounted on the back wall. Setup is the way it is, because I have grown the setup organically over time. AVR is Onkyo TX-NR 7100 with Dirac Live calibration. My testing with your video found that the sound in my room is being matrixed very well based on where it is being placed on the onscreen renderer. This is even with the front speakers being mounted in the ceiling and the rears on the wall. The front staging with the up and down testing was accurate. I think this is because I have the front ceiling mounted speaker mounted right above the fronts. I believe that the accuracy in matrixing of my high channels, which as mentioned in my case are quite different, is because of the Dirac Live calibration. Thank you again for making this video. I finally now understand what my system is cable of and its current performance.

It worked just like your demonstrationI . I sent it from my iMac to my Apple TV in next room and got great result.

Thanks for the demo! I’ve got a 5.2.4 system on a 3700h using Polk OWM3s configured as TF/R/L and TR/R/L. They’re mounted on the ceiling using gimbals and pointed at the MLP. Top fronts are just forward of and in-line with the front towers at 45° to MLP and top rear likewise behind the MLP in line with the surrounds. Positioning and panning matched the illustration and description in the video.

I thought that if the receiver doesn't support auro 3d, atmos speakers should be mounted in-ceiling.. I have the same receiver as you do, so I should actually mount 2 front height and 2 rear height instead of in-ceiling and get better dolby atmos experince? And in Denon configured as front and rear wall mounted speakers. Thanks!

Hi ChannAtmos aka Techno Dolby ;-) Running a Denon x4700h. 5.1.4 for now. Planning to go 7.1.4. Front height & Rear height. Your interactive Atmos mix plays and sound like intended. Well I use DynamicEQ and had to change some sound lvls. Because of the boosted surrounds & rears. Had to lower those a bit. When you had the ball in the middle height, the sound came just from above like it should. And when you go front left to front left height it did go up and down. Again you did it my friend. Great content. I know its time consuming and you put in a lot of effort. Can’t wait for your next release!! I ❤your stuff Dolby should hire you! 😂 A BIG Thank you!!

I'm using on wall for my Atmos and for the most part all the panning was correct using an AVM 90. I did notice an issue when the placement was in the middle of the front and rear heights. The sound was more prominent towards the front instead of being in the middle. I was able to correct the imaging by raising the trim of the rear speaker by about 4dB. My front and rear speakers are a different brands and I've always wondered if that would make much of a difference for Atmos content and this kind of proves that it does.

I have martin logan afx speakers for hight and sometimes its so hard to tell if they are doing what they are supposed to because there is so much going on in the movie.

Thank you for doing what you're doing 🤙 Side note, I uploaded you video to a thumb drive and plugged it into the front of my xbox one just in case anyone was curious how to watch on their HT with the dolby atmos.

Wow, it's so incredibly true!! Immediately I changed the 4 top speakers from ceiling to actual height speakers and the object placement is so much clearer.

hi. thanks for another great atmos demo vid. i have a 5.1.4 setup with height speakers (not ceiling mounted) but top on the back+front walls high up, poited toward listening position. It works very well. movement from earlevel to tops works great. and diagonal move also. My setup matrixes near perfectly to include matrixed sound from top middle. obviously, lack of ceiiling speakers means top-middle (overhead) is less pronounced than say, center (which is also at higher level) for me but top front and top rear are great and atmos also creates faux-top-middle of room effects quite a bit with my heigts. so i am happy with my setup. please keep on making these interesting videos. thanks for the hard work on these.. ps i have a pioneer vsx-lx303, 9 channel + sw avr in 5.1.4 layout. you video made me realise i had my level for rear-height left set too low so i set the db setting a bit higher in my avr channel setup. thanks for a great and instructive video.

In a next video, please do a left, right, both for each speaker pair. (front LR, surround LR, rear surround LR, top front LR, top rear LR) It's also very useful that your video is voice-based, so I could tonally optimise each individual speaker with the equaliser.

Totally agree, I think in ceiling speakers is not the best way to go. Also, if you have in ceiling speakers you can't upmix to Neural:X or Auro-3D. You have to assign height speakers in speaker set-up or the upmix option is not available in Marantz receivers. I now have a 7.1.2 set-up with height speakers and get a tremendous front soundstage. Neural:X upmix from a DTS 5.1 track sounds great (BluRay The Hitman) Still missing the height 2 back speakers, but in time they will come.

OMG, you are finally proving that I am not crazy! In the beginning, I did a 7.1.4 set up for my Auro 3D with the 4 height speakers. The home theater sounded really 3D like with airplane sound coming from the front top, all the way to the back of the room. Then I upgraded the system, made it to basically a overhead placement, and it sounded restricted. Just sudden height sounds but disappears. I have been telling people to set it up with height speakers, and they all think I am crazy.

Hello, Techno Dad. Dolby Lab at the time, was too busy competing with DTSX, but failed on understanding thier atmos platform itself. When, creating atmos, it requires from users to calibrate thier listening room into a 3 dimensional 180° half sphere. Which means the thier height speakers are in thier correct placements, however our room isn't a half sphere, its either square or rectangular shape. So it completely throws out thier dolby concept. What users needs to do is to install front and rear heights speakers instead. We're got two layers of speakers working together, e.g. bed levels and F/R height levels. You'll have better imagining and steering sounds that way. For example, in the movie Back to the Future, in the scene, when the clock tower gets struck by lightning. The front height channels engages in that track, they gives the presence of elevation!! The sound resonates rearward towards rear heights, completing the heights channels sequence. Dolby Atmos, is a object based surround sound experience, but the way they're suggesting the in- ceiling speaker's placement is down right wrong.

Thanks so much for this video @Techno Dad. I wasn't sure if my Atmos setup was working properly (I just purchased all the equipment over the holidays), and this was a much easier test to use than trying to find good Atmos movie scenes and then trying to mute all but the Atmos speakers. So my equipment: I am using a Denon AVR-X3800h. I have Kef Q Series speakers in a 5.1.4 configuration. My Atmos speakers are the Q50a upfiring speakers. I know you mentioned you wanted to test specially heights and in-ceiling, but you might find my results interesting. I have the Atmos speakers setup in the Dolby upfiring mode (I might set them up with brackets as heights to see if my results and effects improve, or I might leave well enough alone, I haven't fully decided yet). Results: I heard all the sounds exactly where they should be, except for the top right corner of the room. There I had an issue where it sounded more like it was from almost the same position as the rear surround. I'll have to make sure I am setup according to the proper Dolby distances and re-calibrate the system to retest since it is odd all the other locations worked flawlessly. I guess upfiring speakers can work!😁

Great video, top stuff. I rent so I cannot put ceiling speakers in so I have been putting my speakers at 30 degrees on stands like Auro 3D layout and totally love the sound, now you come out with this video and confirm what I am hearing as being correct. Yeah I'm happy, thanks.

Love the technical aspect of your vids with Atmos. One thing o did wonder and I haven’t had time to play with and recalibrate etc is does changing between Top vs Height on the AVR have much effect on sound placement, have you played with that much? (Personally I have TF and TR speakers in-ceiling)

I just moved 2 days ago my dolby placed instructions to forward height like your telling in your video. And your right. Even my Sony dn 1080 sounds so much better. Even with fathom sound field. Now need to watch all my movies again. I have an angled roof and a standard 5.1 setup my aft speaker are bit above ear height. Just love the new sound setup. So much more object location in the living room.

Only just found this video and i love this demo. It works very well for my up-firing Dolby speakers. But top centre to top centre back is a problem because my Dolby speakers are surround heights, not surround back heights. So the pan from above me to behind me doesn't work as well as it should. I did a test rewire and speaker substitution and your demo now works perfectly. So now I have to properly move my surround heights to the back and buy some more speaker wire. When they say ignorance is bliss I'm not sure about that. But it sure is less hassle and expense :)

Ok well I am not the target you are looking for comments from (5.1.2 Upfiring, Denon) , but since I appreciate your hard work and this was a great test of my currently limited setup which I am actually investigating upgrading and seriously looking at front height vs ceiling speakers. With 2 Dolby upfiring any height info you sent front or back or middle it was all sent to the upfiring speaker. This really highlighted how bad upfiring speakers are as its so easy to locate the sound origin. What actually did an ok, slightly better job was when you were in height overhead, the matrix effect between the 2 dolby upfiring speakers took away most of the ability to locate the sound coming from the speaker and made it seem like it was somewhere overhead.

Currently have Atmos 5.2.4 Configuration with wall mounted Height rather than in ceiling. Front Heights mounted on wall near ceiling, not quite (but almost) directly above L/R Mains. Rear Heights are side wall mounted (near ceiling), close to where top corners where side and back walls meet. Height locations are limitations imposed by the Living Room layout (and wife acceptance factor). My Denon Receiver with Audyssey xt32 appears have done a pretty decent job with the room calibration. When running your Atmos demo: The location movement from L/R Front to Front L/R Heights and to the "Above" Central Height location was all handled fairly well. Even my wife (who is not into these things, and just "puts up with it") was able to notice it. My Atmos Height setup is currently a Frankenstein's Monster of mixed speaker brands. Front and Rear Height Speakers are from different manufactures, so heights are not timber matched. I normally dont notice the timber differences with regular ATMOS effects/content. However, this demo consists of your "voice" moving. The timber differences were OBVIOUS when a voice was moving from Front Height to Rear Height locations.

Great video. I think a lot of people don’t understand that they only reason the Dolby speaker layout is the way it is was they didn’t want to get sued by Auro3D and they didn’t want to pay Auro a licensing fee. It was a comprise. Hindsight being what it is I think Auro should have just let them use it because it might have Studios more willing to do Auro3D mixes as well.

I don't know where this rumor started, but it's simply not true. Auro-3D was originally developed as a music format, derived from experiments in surround music recording and playback that found that adding front and surround heights were greatly beneficial for that purpose. The format was later extended to cinemas. Atmos was developed for cinemas from the start, and as such never envisioned using surround heights, it only ever had top channels plus additional speakers in the surround arrays for object rendering. The home theatre implementation of Atmos simply followed this same paradigm, it had nothing to do with Auro licensing fees.

Great & informative video. I got into ATMOS a few years ago with a Yamaha 5.2.2 RX860. I used 2 klipsch atmos wall mount speakers behind my 2 front towers. for atmos/ effects. I considered ceiling mount speakers, but, intuitively, I didnt think the imaging would work as well as wall mount, keeping in mind that I'd be upgrading to at least a 5.2.4 as the technology matured and prices became more affordable for me. I just had the DENON 3800 delivered the other day, along with 2 more wall mount Atmos speakers. Its going to get hooked up this weekend. Your videos have been incredibly helpful in how I will be laying it all out. Its a family living room, not a dedicated theater room, so it wont be optimal, compromises will be necessary, but between your tips, and the onboard DSP ( or is it sorcery?) I am confident its going to be amazing. Im really stoked about the 4 discreet subwoofer outputs and bass management. I use 3 subs and have issues with dead spots, in room resonance and bass bleeding into other parts of the house. The Denon 3800 should make a dramatic improvement over the Yammy 860.

I’ve been into home theater since the 80’s and have dutifully upgraded each time there was a new format. I’ve tried to follow the Dolby specs as close as possible and have never really been very impressed with most movies (with a few exceptions, e.g., The Harry Potter series). Until you and your associates created some much needed clarity on speaker positioning and your interviews with Wilfred, I believed the reason there was so little envelopment with surround were poor mixes.

Woot woot!!

Running a 5.2.6 setup with an Anthem 1140. - Top middle is designated “middle in-ceiling” and an actual in ceiling speaker - Top Front is designated “Front on wall” and is a ceiling mounted speaker angled towards the row of seats (but not toed-in to MLP). These speakers are located 45 degrees - halfway between seating and front wall. - Top back are designated “Back on wall”. These speakers are angle mounted towards seating and are at the ceiling/wall junction - Theatre Area is small - 12’ from front to back and 7.5’ ceiling - Seating is 2’ from wall. I loved your test video(s) and are great system tests. Results: 1. When you played the middle content, only my middle were is use. So if both backs/fronts are supposed to be in use in a .4 system, and middle only in a .6 … its working. 2. Panning around the room, bed layer, and height layer was as per expected. 3. Room size perception and separation of bed/height layers. Even though my front heights are halfway, they don’t make the height layer seem small. They actually do the opposite and open up the top. At their location they provide very good separation between bed/height due to my lower ceiling height. If they were further to the front that separation would be eroded. So while not ideal for going straight up from bed to height (your left speaker example) as mine does move in. The setup is much better for overhead effects and panning - helicopters, rain …etc., which is a higher priority for me. Hope that helps

Great video and even greater demos! I can say admirations to you Channa! I will say it for everyone who had doubts as myself. What sound format is better...what speakers placement is better...etc. Well out there is full of "specialists" and "pros" who claims that they know better. What is "better"? My post is not to praise one format or speaker configuration and to disregard another. It is for pure simple field test. I have Denon X6400H (5.1.4 currently) With Atmos, DTS-X and Auro-3D As I have hard ceiling and I am renting, I was forced to place permanently my speakers with classic Auro-3D placement (front and rear hights) When I play native Atmos or DTS-X demos and movies on my system, everything sounds AMAZING and Immersive. But I always had the question, if my upper speakers were in the ceiling. I couldn't find native Atmos channels call out demo until now. So I didn't know how my system should sound. Well here you go now fully confirmed! My speakers setup is 5.1.4 (with hights) My friend's setup same 5.1.4 (in ceiling strictly the same as Dolby recommendation) Same receiver model X6400H With my system the sound was precisely where the diagram was showing! With his setup the sound was in very weired placement...not acurate at all. Recalibrated sysstem several times and same result. We placed temporary at his place a small hight speakers above the main bed-layer to replace the in ceiling. Again calibration and guess what happened... Now everything was in his correct place. It was so much physical efforts to do this test, but the result was solid. So I have a message to all haters of Auro-3D. Forget about the format and all business sh...t between the companies and their marketing. Stop being cocky and defend furiously "in ceiling" as is the Holy Grail. It is NOT! Be on the normall people side. Native Atmos (well mixed on Atmos render) sound acurate on Auro-3D speaker setup!

Very good presentation, I wonder if the ceiling is low at 8.7 feet the 30 angle placement will be in-ceiling

Well done! I have been wondering about this myself for a while. I am running a Marantz SR7012 7.2.4 setuP. 4 height channel wide dispersion speakers firing straight down from 9ft ceiling between 45 and 50 degrees from MLP. Everything seemed to matrix well. At the extreme front to height transition, sound does move at a diagonal. However, when the transition is a third to half of the way between front and front height channel, it sounds like I believe it should. Maybe, it just depends on how aggressive the transitions are in the mix. It seems that each immersive sound mix file should contain qualifying data that could work with room correction software and apply appropriate transitional delays in real time too correct for different speaker layouts and rooms. Denon x3800h arriving today will give me a few more speaker layout options to try as well as more sub control. Also, allow me to try Dirac eventually. Cheers!

With 4 in ceiling speakers it sounded perfect. Tried with temp height channels. Didn't notice much difference between

Channa, My system is 7.2.4 consisting of the following: Denon X-6700H, Oppo UDP-205, Klipsch speakers exclusively, consisting of the following: A pair of RP-8060FAs For fronts (not using the built-in ATMOS speakers), RP-450C center channel, A pair of RP-150Ms for side surround, 1 SPL-15 Sub, 1 R-115SW, Sub, A pair of R-5800-W IIs for rear surround, and 4 CDT-5800-C II in-ceiling speakers. I calibrated the Denon with the Denon app. My wife and I ran the interactive video more than once and both of us agree that the sound appears where it is supposed to. The ceiling speakers point down and the tweeters are aimed at the center of the room. Our seating portion if very close to the center of the room. My room acoustics are far from perfect.

I just set my 5.1.2 with top middle atmos, and I only hear some specific sound, like airplanes on top, but for example, in Matrix, when neo are using the glattling gun to save Morpheus, the sound comes from the front tower speakers and not the top atmos

Thank you for the info.

Ok just tested this on my system. I'm running 5.2.4 with 4 in ceilings as per Dolby. Yes when the sound goes from front left to top front left it does go right up but slightly towards you - however it is still distinctly above and far forward. At the end of that transition from FL to FTL, the sound came entirely out of the top front left speaker. So it doesn't feel odd or that the sound is coming from somewhere it isn't supposed to. After running the whole video, my conclusion was that the point you are making is a valid one, BUT it doesn't really matter in terms of practical reality as the sound does come mostly from where you expect it to. I really enjoyed this demo and overall made me happy that my system works as intended - thank you for making one of the best Atmos demo files too btw.

I have a 7.1.4 with lx505 playing on an nvidia shield. I have 4 cheap in-ceiling speakers down firing. The sound was played correctly in terms of speakers in respects to object placement. My in-ceiling speakers are closer physically then other speakers. So when it the sound was played in the height it was closer so the depth may not be accurately represented in respects to the object viewer. But I do think you have a point in terms of room vs speaker boundary. I wonder if the "Box" was represented as a "Sphere" could that make it better.

My setup is a bit strange. it was a 5.2.4, but i recently changed it to a 7.2.2; keeping the rear height speakers (not in ceiling). Using a Denon X3700, all the channels i could hear worked perfectly until you did the upper center section. then the sound came from the rear heights, even though the sound was in front of me. it sounded like the sound was over me and it wasn't bad. just weird. All my speakers are Mirage Nano-sat Prestige. pieced it together on a budget.

Enjoyed this demo video. So I have a Marantz SR5015 in a 5.2.2+ setup where I have powered Klipsch R-15PM (connected via the pre-outs) placed up high (about 14 feet) in the front height position along with Klipsch R-14SA (up-firing) sitting on my rear dipole surrounds. Also, my room has a really high vaulted pitched ceiling that in the front is about 20 feet high but slopes to about 10 feet in the rear. So in my Marantz, I have atmos set up as Top Middle. So as expected I got great L-to-R separation for the atmos effect but not any real true front-to-back. While it would be cool to upgrade I'm perfectly happy with my setup at this time as I still get a great immersive experience and dome of sound. The use of the pre-outs and a pair of powered speakers allows me to cheat a bit to get a pseudo 5.2.4 setup experience albeit again without front-to-back height separation.

Question for you (or anyone who wants to chime in). In my setup I'm forced to have my couch against the back wall. Should I do 5.1.2 or 5.1.4? I was going to do in wall for the surround and in ceiling speakers for the Atmos (after watching the video I'm considering height speakers instead. Small room 12' wide, 15' deep with 8' ceiling. Does the 5.1.2 setup make more sense since my back is to the wall? Thanks!

So we should put Atmos speakers in the front and back corner heights of the room?

Just finished listening to the demo. Here’s my setup. When i built the house, I had the builders install a 5.1 in ceiling setup (back when I didn’t know anything about proper speaker placement). 2yrs later i now have a 5.1.4 setup. I’m utilizing the 4 in ceiling speakers as atmos. Here’s the problem though. When watching movies with atmos mixes, the majority of the time, I can’t tell if the sound is coming from the L&R floor speakers or the L&R ceiling speakers. The same happened with the demo. I tried to create as much separation as I could get away with but it’s still not enough to make a big difference. Based on the demo, I could def hear the difference in where the sound was coming from all the locations which was really cool. The only time it was a little hard to distinguish the sound was when your voice was shifting from up and down between the L&R floor and L&R ceiling speakers. When moving from floor to ceiling, it basically sounds as if the volume was raised on the floor speaker. If I focus my hearing though, it does sound like it’s coming from the corner ceiling, but it’s very subtle. I have taken into account that some movies/shows just have bad mixes &/or just don’t utilize the height channels as much as we would like. Especially since the majority of the content that I watch is through streaming, which is not as good as physical media. I’m debating whether I need to raise the DB on my ceiling speakers or if I should invest in new ones like kef in ceiling speakers that have a 160 degree off axis dispersion. I would like to send a picture of my setup to further discuss what I’m dealing with if that’s possible?

Timely, was just about to build a truss overhead for four heights. I hadn’t heard about the lawsuit and always wondered how height channels can create a point source with that is discernible with such a wide gap between ear level and ceiling. Will have to try the heights on wall like the auto standard. I reckon that will produce a sound with a position that disperses the sound quite differently to the ears in terms of localization.

Incredible videos. I’ve downloaded all 3. Thank you. I already had 4 heights but it helped me get a sense for speaker placement and what my room is doing to the sound. One thing I’ve noticed is all my hearts make you voice sound a lot deeper (boomier). I assume this will be due to the speakers being in the corner of my rooms the base is getting caught and bouncing around a lot more than my surround speakers? Excellent work. Thanks for your efforts. Long time watcher, now subscriber! (Sorry)

Hello Techno! So if I understand correctly I should use 2 front height and 2 back height wall mounted, instead of 4 in-ceiling speakers? With my Denon X3700h and 7.1.4 setup, eventhough auro 3d isn't supported. Then configure speakers in Denon as 2 front height and 2 back height. (=no in-ceiling speakers). I still can't understand how these height speakers can make better sound experience when for example airplane is flying above your head. Thanks for your reply! 🙂

Interesting test, here is my less than ideal findings using a Trinnov 16 which is supposed to use Dolbys Golden code I'm using 9.1.6 my inital Atmos layout was to get near to Dolbys layout using FL Top and FR Top along with RHL RHR The FHL and FHR test came direct from the Tops with no matrixing to the front, the centre phantom came from the FL Top and FR Top I enabled FHL and FHR then the FH tests seemed to come from both the FH and Top speakers although the Trinnov display only showed F Heights as being active so I muted the Tops then the test clearly came from the FH speakers, FH centre phantom was as expected With 4 Heights there was no clear above your head voice, it was coming from the phantom centre of the Rear Heights there was no FH and RH speakers phantom sidewall centre, the voice was clearly coming from the RHL and RHR speakers only As side and top phantom imaging didnt work that goes some way to explain my disappointment with Atmos content Sidenote: having thought about it I think there is a step missing and that is "Check your mains and heights are level mached" it seemed clear that my FH are not level matched with my L/R or RH so will do that later and retest

I have been arguing this point for about 2 years now, and always fail to get thru to anybody. Not only does it work for Atmos, but makes the setup more universal for DTS:X and Auro 3D. Now at some point a year or two ago I did see documentation that the heights are now approved for Atmos, but I am having trouble finding that documentation and only finding the old setup guides. I think the KEY here is not just slapping height speakers up, but ensure they are angled properly. I used a laser level for this and I clearly here separation for height speakers. The analogy I used to use was a helicopter. If a helicopter is in the distance, going straight up and then flying overhead that sound source needs to be able to go straight up in the air not be moving towards you as it rises like it would do with in ceiling speakers, the same way an object pans left to right is by fading it from left to right, that is exactly how an object moves from to back. So that object should not move forward towards you just by going "up" and the only way to do that sonically and correctly is having your height speakers in line with your front mains. then as it starts moving towards you it would start to fade to the rear heights. Full control of positioning both vertical and horizontal. If you pan left to right in line, it just makes sense to pan down to up in line as well. Problem is, while this is the RIGHT way to do it, its all about the Atmos mix, most mixes are just random sounds and effects and not true 3D audio. They may very well only mix in a sound effect that is an "overhead" effect, that works well with in-ceiling speakers rather than take advantage of what could be a really immersive 3D audio experience. The Atmos in ceiling setup is fundamentally broken and flawed, but nobody understands or agrees. But I am an Audio guy and I.T. Engineer I think differently, as I don't just listen to what is said, I think and learn. I have a Ambisonic 3D microphone setup and have done my own testing so that users without an Atmos setup can look around in VR to hear my setup and see how it works.

I’m looking to do a 5.2.4 system right now. Had a home theater installer come out today actually . Initially I wanted to do my rear speakers mounted on the wall above where our couch is against and 4 in ceiling speakers for atmos . Should I do the rear surround speakers still on the wall and then place 2 height speakers in the middle of the room LR and 2 more LR closer to the front instead of the 4 in ceiling? So basically I would have LCR normal 4 height speakers in a cube format and 2 rear surround mounted above sitting position in the back of the room. Thanks

Hey I have a question. My entire set up is Sony. I have a 5.1 Sony receiver for my surroundsound. I just purchased two Dolby speakers that can be mounted on the top of the front shelf speakers or high up on the wall close to the ceiling. My question is can I connect the Dolby speakers to the subwoofer terminals since the receiver speaker connections are all occupied?

So if using a 7.1.6 would you get the sound you want put of the middle hight speakers?

I played the demo on my 5.1.2 system Denon X4500H .2 are front height speakers. Front height were quiet spot on in their presentation, Up Down was perfect only when it went to back height it sounded like sound was matrixed from rear and front height or may be just rear speakers. Even the Top center sounded like it came from front height.. other wise the demo was superb and truly was able to experience Atmos mix. One more observation i want to point out here. Denon is capable of Auro3D when i switched the sound process from Atmos to Auro3D all the height channel output was actually played through the front channels and none from the height speakers. which was quiet a surrprise. Ideally Auro3D should be able to utilise the height channel and play it well.. but well it just didnt!.

Auro cant access the height information encoded in Atmos. For me also everything was playing on the floor. But in the corners there was a strong reverb with Auro. I tested with some Movies like Blade-runner or edge of tomorrow how good Auro can reproduce height information by up-mixing. And with movies the algorithm is astonishingly good. Perhaps it just did not got the information needed to place TD in the heights. I always use Auro3D on Atmos tracks. Not because Atmos is bad by itself but because the production of Atmos tracks in Hollywood is FUBAR. But this is another topic. End of line for me is, even if, and this is a big if, Auro has sometimes less quality in the heights than Atmos, it still makes the whole movie sound better. And I take a whole movie anytime over 5 seconds or less in two hours.

I have a Denon 4800h with a 5.2.4 setup and my first 5 are standard and 4 overhead but I've been curious if my rear heights would be better as back surround , dolby sp ,or keep it as I have it setup as rear heights? Keep in Mind my seating position is against the wall like yours. Let me know what you think. Mind my new denon 4800h can do auro 3d , auro 2d ..etc . I do like how my Neural X sound , I think it sounds better than Atmos . I'm open for thoughts and opinion Techno Dad.

Unless of course if front channel is also used along with ceiling speakers, imaging gets better, because now the object can be placed between those two speakers. But I am not sure if atmos does that.

Excellent video and explanation!

Thanks, man!

I have vaulted ceilings. What are my options? Just directional in-wall speaker? How high can I place them?

I have hight channels. They are in ceiling speakers I put up high in the wall. I have a 4500 h denon 7.3.4 but my rear surrounds are not far enough behind me because of normal house problems. Ur demo was awesome though it voice was located perfectly. I definitely think ur voice would have been out of position with in ceiling speakers. Thanks for the content

Hi Chris! Thank you!

when it comes to surround side and back, what would be preferable between inwall speakers and having bookshelf or bipole as surround?

My playback was fine on a Shield, via Plex. My system in a Denon 3600H and I’m running 5.3.4. Seating is 30” from rear wall and 7’6” ceiling height. I recently moved my height channels from a FH/RH setup to a TF/TR setup. The FH/RH were just wall mounted shooting straight out and followed Dolby spec showing aligned with FL/FR. I saw some recently published videos from hometheatregurus channel suggesting different positions based on angles from Dolbys studio spec and aimed at the MLP. I feel like it’s a completely different and much better experience. My TF is 50 degrees and TR is 110 for a 60 degree separation between them viewed from the side. Viewed from the front they are 50 degrees overhead (45 degrees separation from surrounds) from the MLP plane. Technically the TM is the position for 110 degrees BUT your video with the plane flying overhead is 100% more convincing when that speaker is assigned to TR. It actually sounded like the plane came at, over and away. The TM did not provide that effect at all. When your voice moved from FL to TF it felt like it came closer to me. Makes sense, the speaker is much closer to me. The full TF/TR did matrix was centered but it felt closer to me then the center channel. The rear only effects sounded behind and above. Overall, at no point did the sound appear to come from the location in the rendering box. Just a thought though; the program displays the audio space as a square, but isn’t the point of Atmos to be a sphere of sound? I feel like the program should give you a sphere to design within and not a cube.

The interface is meant as an abstraction to represent a large room. We hear in terms of direction, so fundamentally, the point of all the immersive formats is to create a sphere of sound.

@@TheReverendSlim my room is not perfect by any means but when Channa had the sound in the top left/right corners of that cube it played only from the TL/TR and the sound location did not match the screen IMO.

So I actually didn’t understand the assignment. I didn’t watch the rest of this video lol

When one is sound from above, the sound is usually off in the distance first, hence the reason why I chose to go with height speakers.

My listening position (single recliner in my bedroom) is off-canter with room dimensions. If I were to get a couple height speakers to achieve a 7.1.2, would I need to place them right above my mail L/R speakers or all the way in the corners of the room? PS should my side surrounds be at ear level or slightly above - my rears are higher because of the chair back.

What is very noticeable is that when I turn on the 4 upper speakers from Height to Top in the settings menu of my Yamaha RX A 2070, the voice sounds like a kind of reverb when it is centered above my head, i.e. when all 4 upper speakers are controlled simultaneously. This makes it sound diffuse from higher up. If I set this back to Height, the diffuse reverberation is gone. Somehow the Atmos algorithm in the top setting works in a way that alienates the signal, perhaps to close the gap in the distance between the floor and ceiling speakers via the diffuse reproduction

What I can appreciate about my 3 yr old setup, is that my ceiling is low and evenly flat. My room is a perfect square that my system calibrated the height up-firing channels at an angle. It sounds like the object based sound is placed correctly...depending on the content that has been up mixed correctly.

Nice!

I have 6 in-ceiling speakers, 1 rear high 7.5 feet tall wall speakers and 3 ear level speakers and adding 4 ear level speakers across the listeners postion. Soon to be 7.7.2. I need a 20 channel receiver. I want to add a back level speaker
