I agree it's not about speaker placement and just the object placement, but that engineer had a specific monitoring format and speaker placement in the studio that he used to place the objects. i think that's where the point comes in about mimicking the studio. You're just not going to place objects blind, you need to listen and verify on some kind of an Atmos setup as it's being mixed just as you've been doing and that could influence the object placement.
Agreed
Agreed
yes, they don't just visually place it in a 3D box and call it quits; they're using their ears to hear what it sounds like at that 3 dimensional xyz location that they've placed it in (using their speaker layout). at least that's how I understand it
@@enigmaticfool totally agree, if the object movement that the sound enginners "drew" with the panner does not sound according the intention in the studio (on that particular speaker layout), I'd assume they would rather listen to their ears and correct the object movement "trajectory" than to rely on what they see in the renderer. As in the end we will not watch but only listen to the soundtrack. :)
wrong because dolby atmos has 2 beds of informations. Object based sound for up to 16 object at any given time + channel based content that is mixed like the predessesor. So the channel data will be wrong if you dont place your speakers acordingly. Also in most scenarios you cant change the angles and relative positions to the listener of the speakers which would be needed to translate the position information of the object accordingly to your space. Also if the imaging gap is to wide for speakers the imaging will just break lose. So there are multiple factors to stick as close as posible to the standard layout even IF you have object based source material because you gonna strech your imaging into a mess.
This should be titled "MIXING for Atmos is all about the meta-data". Positioning speakers is a different topic. Speaker placement is more about the room and recommended angles, distances, etc. so that the playback system can accurately represent where the Atmos renderer is 'saying' those objects are in space. Putting atmos speakers in a corner of the room sounds like a terrible idea. Boundary interference alone tells us that's a bad idea. The object being in a 'corner' should sound like it's 'beyond' the speaker if you have the angles and phantom centers, etc. setup correctly. Neither the Home or Studio versions of Atmos' guides tell you to do that. I don't understand the point of this video, other than saying you can mix atmos by sight, without the need for any room or speakers...
This is the correct answer
Who is your Metadata Daddy and what does he do!?!?!? 🤣😭🤣😭❤🔥❤🔥
LOLOLOL!!!
@@TechnoDad I need it to be as it was supposed to be, 9.1.4 or 7.1.6, extra middle Atmos worth it? Or extra front wides?
If this were true, I’m pretty sure Dolby would’ve said this from the get go as front and back height speakers are way more convenient and plausible to the average consumer than cutting holes in your ceiling. Just a thought.
There could be a patent issue with that speaker layout which is why it's not suggested, but I'm not 100% sure...
@@TechnoDad Oh, that makes sense. Hmmm, I guess the mystery rolls on. Lol
This height concept is there since Dolby PLIIz and no patent infringement dispute happened yet.
THANKS 😊👍 FOR SHARING THIS!!!!! This video should be sent to sound engeniers so they can mix Dolby Atmos CORRECTLY. I switched my setup back to 5.1.4 from 7.1.2 today. I now hear the matrixing between the height speakers as it should be. We need more content like this
Cool shirt Channa! 😎
Thanks for all of the quality content. 🙏🏻
Thank you for the time you devote to helping us along, I’ve been enjoying your content! I’m new’ish to the more advanced side of home theater setups and in particular, to Atmos…but I’m in the process of buying new hardware and I have some questions which I hope are not too long or cumbersome!
1. *2 CHEAP (old) AVRs vs 1 EXPENSIVE ONE?*
For the budget-minded, rather than buying one of the newer AVRs that offer all the channel outputs needed to have tons of speakers, could someone use 2 (older and cheaper) machines to power the same number of speakers…and still get proper Atmos configurations?
2. *DO OLDER AVRs HAVE PROPER ATMOS OUTPUTS?*
There are used Denons selling online, like the AVR-3312Ci for around $100. While on the back it has 1 set of “Height” outputs, it doesn’t say Dolby Atmos on the machine. Are all “Height” outputs on older AVRs sending data properly to overhead speakers? The AVR-3312Ci does say Dolby TrueHD, DTS-HD amongst other things, but not Atmos. Does a receiver *have to be* Atmos specific in order to pass the data/sound properly to the speakers that would be setup as ceiling/upwards-facing speakers (not to mention the ground-level speakers that Atmos communicates with)?
3. *2 AVR’s? -or 1 AVR + 1 AMPLIFIER?*
If the answer to question 1 is that yes, (you can buy a cheaper AVR to receive all the HDMI (and other) inputs from your sources…and if said AVR doesn’t have enough channel outputs to power 5-7 ground-level speakers AND 2-6 ceiling/upwards-facing speakers) …would one be able to use the pre outs to power an additional amplifier? -or would it need to be another AVR, to get the proper Atmos configured output to the speakers?
4. *REGARDING THE SPEAKERS.*
If I put together the right AVR system (whether a single unit, or a combination of 2 or more) to power (up to) 7 ground-level speakers, plus 1 (2, or 3) sub-woofers, plus (up to) 6 ceiling (or upward-facing) speakers, can I mismatch different speakers and brands? For instance, I recently bought a set of Klipsch Reference Theater pack (before I knew about the Reference Cinema pack). If I keep the Theater pack and buy 2 more ground-level speakers…AS WELL as some overhead speakers (whether ceiling-mounted, or other) …could I shop around to add to this array, even if I end up getting cheap ceiling speakers? The ceiling speakers (round ones that install into the ceiling) seem pricey compared to the set 5.1 set I just bought. If I shop around and buy other brand speakers (whether the round ones made specifically for ceiling use or not), would that yield workable results?
5. *KLIPSCH UPWARD-FACING vs CEILING SPEAKERS.*
Which are better? Would the Reference Cinema pack be a better option for having Atmos “ceiling sound” rather than using the Reference Theater pack and adding cheaper ceiling speakers (mounted on the ceilings and pointing down)?
Thanks in advance!
The layuot is a compromise to what the metadata is trying to portray. Where does the metadata spend most of its time. It appears to me from your example that it lives somewhere in the "80%" space 99% of the time. SO shouldnt we chose the layout that is going to give us the best possible effect 99% of the time. I think that if all you have is a .4 then placing them in the corners would compromise the effects intended to be rendered more towards the center of the room. This is even more true when you factor in room size. How many of us have rooms with 10' ceilings to give enough space between bed layer and height speakers. My current layout is 5.4.4 with heights in the corners. I like it but I am only able to space my height channels 4' above the bed layer. More often than not, atmos is heard only in the front and rear of the room leaving a huge dead spot in the center. Have you tried an effect that moves slowly across the ceiling from top right front to top left rear to see which of your layouts portray this effect the best?
I tried signing up to your news letter and it didnt work.
I must ask - How does the processor know / configure ' where ' each speaker is placed exactly?
... I am thinking: Doing the Room Calibration Mic sweep helps the processor calulate the object location more accurately ...say .. opposed to now doing the mic sweep and telling the software that it's 7.2.4 and assuming each speaker is in the " standared " location...
Most procesors use the speaker positions you tell it you have in the Amp assign. Front Left, Front Right, Center etc. Those are embedded in the processor as pre-defined positions that your processor uses to generate the desired soundfield.
Some more advanced processors like the Trinnov, actually use their specialized microphones to actually map out the speaker positions in your room. Instead of the positions being generalized like in most receivers and processors, the 3D mappping feature tells the processor exactly where your speakers are during the calibration process. Supposedly, Yamaha receivers and YPAO maps your speaker positions as well (unsure how well it does this. Certainly not as effective as Trinnov)
It seems like the debate is whether Atmos is based on a rectangular/Cartesian system to place the metadata, or if it's a polar coordinate system. If it is a polar system, they should change that cube to a sphere and change the drop-down options and sliders from an xyz and angles and radius instead. From the visual it seems like a rectangular system and mixers will mix according to that system. It makes sense to have a rectangular layout if it's a rectangular system as depicted in the Atmos renderer.
Another point of discussion is whether Dolby Atmos is room-referenced or a mixer-referenced. It sure seems based on your demonstration that it is mixer-referenced.
I like that, room-referenced vs mixer-referenced.
I Ran Audyssey MultEQ-X calibration and it gave me some weird crossover results.
Equipment:
Denon X6700H
Emotiva XPA-3 GEN 3- for LRC
Emotiva BasX A 4 channel amp- for Surround and back surrounds.
Emotiva BasX A 6 channel amp - for Surround wide L & R, and 4 in ceiling Dolby Atmos.
Speakers:
L&R Klipsch RP-8000F
Center- RP-504C
Surround Wide's- PRO-180RPW
Surround-PRO-160RPW
Surround Backs- RP-502S
In ceiling Atmos- PRO-18RC.
After running Audyssey, it set my crossovers as such.
Crossover:
L&R - 40hz
Center - 60hz
Surr. Wide 70hz and 80hz
Surr. - 120hz
Surr. Back- 90hz
Atmos top front - 80hz
Atmos top back - 40hz and 50hz.
Because I change the initial calibration, it no longer sets my fronts to large. I set everything to small and set the following crossover:
L & R - 80hz
Center - 80hz
Front wide - 100hz
Surr. 120hz
Surr. back - 90hz
Atmos - 110hz
Subwoofer is 40hz - 120hz.
Do you have any suggestion and why did Audyssey set my crossover so low for my Dolby Atmos speakers, and did I make the right changes? Should I've left the calibration the way Audyssey set it? Also, should I factory reset my Denon X6700H and rerun Audyssey? What are you're recommendations.
I might add, my room is very well acoustically treated. Any assistance would be appreciated.
I'm now running my fronts at 60HZ Surr. wide's at 80HZ, Surr. at 80HZ, Surr. backs 80 HZ and 4 in-ceiling Atmos 80HZ.
To me the 60HZ sound better when watching 4K Blu-ray movies. I have a few questions, 1. The AVR has the subs set to 120hz, is this good? 2nd, should I pull my curtain in from 20000hz to 500hz, or leave it as is? I have 4 subs in my home theater using RCA y-adapters to connect 2 subs back to AVR, 2 in the front and 2 in the back. They are all set to 0 phase. Should I have the ones in the back on 180? or leave them all on 0? Any advice would be appreciated. Thank you.
So in one part of the hi fi podcast you guys said this isn’t about starting drama, Then here you take a cheap shot at Steve (not selling you room plans)…..why do you feel that’s necessary? Seriously asking. I mean,,,,,you mention patreon on almost every video you publish…..that’s selling….you’re selling yourself as having content worth paying for right? What am I missing here?
I'm after getting the best Dolby Atmos experience. I do not have any incentive which one you choose, I could care less. But, there are some who have built a life around presenting 'A' as the best setup. I've been making Atmos for a while and since I have two Dolby Atmos setups in my home, one with setup that is like 'A' and another setup that we will call 'B'. After months of creating Atmos and testing on both systems A and B, I find that system B is a better bet for the most compatibility with all immersive audio formats. If people want to support me on Patreon, that is their choice, I am not selling anything. I am not designing a home theater...think about what you are trying to compare. If I do sell something, you will know it.
Gday Techo, I love your content mate, but this one I am going to respectfully disagree. It is however good to see different views on how this all works.
1. My room is not a cube, and nor should any decent room be a cube, so putting front atmos on the top front wall will just destroy the channel separation between the LCR and front atmos.
2. So my room is 8.5m (28ft) long, if my atmos are as you recommended I would have a 28ft gap in my front and rear atmos and only a 4-5ft gap between my LCR and front atmos, that’s ridiculous.
It’s going to sound like shit.
Anyway, loving this discussion and hoping some others chime in.
Glad you mentioned Steve's video. I was talking with him on his channel about your recent videos. So I know you mentioned 4 heights with 2 top middles is ideal. Are your 4 heights angled down toward you or they flush with the wall shooting straight? It looks like in your studio here your rear heights are angled down towards you. Also do you have the height channels as heights or tops in your AVR? I know each AVR processes stuff different depending on if the speaker is labeled as height or top.
Hi will a normal blu ray disc (Transformers Age of Extinction) that has Atmos sound the same as a 4K UHD version with Atmos
I wouldn’t see why there would be a difference. It would cost the studio more to make if a different Atmos track.
Mr atmos your the best keep make those videos because they are great we spend a lot of money for this machines
Right on, David! Thank you for watching!
how do you make a "speaker layout that coincides with this cube" as you suggest? isn't that what the whole speaker layout debate is about in the first place?
Yes! Check out the other videos - ua-cam.com/video/DWjZZwIe71w/v-deo.html - and then watch this one - ua-cam.com/video/5FSBMUNmMyE/v-deo.html - that should give you an idea of what I think is the best setup for Atmos.
You are right and it's a cool video but turn your head slightly and the sound will seem like it's coming from a different place again. I don't think you really need to be that accurate. Steve is right. Separation is far more important for the effect even if what you end up with isn't exactly what Dolby say or technically where the sound comes from.
Is this why the call out you sent me for my 7.1.4 is confusing?
Not sure what's going on with that...
Great explanation of the object based tracking 😎👍
You should send a link to the Disney+ team so they can make Atmos metadata work in their streaming device apps 😂
LOL! I'm not sure I can help the folks at Disney+!!!
Excellent explanation
Thank you, David!
Mr. Atmos it is 😁
Woot woot!!
All hail Mr. Atmos!!!!
Lol!
Great video and very clear with good points. It’s also “only” about a single unified mastering and delivery format. It’s also only about a universal delivery format from binaural through…. It’s also only about object-based stems mastering.
Next bogus theory is that Atmos is still in the computer even at studio. As per this theory studio also don't have the "atmos" so this techno says it doesn't make sense to replicate the studio. Then what is Director's intend which everyone is after. Director hears what the studio has. Seems people are looking for something beyond Director's intend...
I was so looking forward to doing an Atmos mix of my new record, then saw the distributor charging $25 per track just for Atmos meta data upload… no
Yeah, it's not cheap for sure!
To perfectly honest I think Dolby Atmos is not worth the wait. I just put my settings now on multi channel so I can get my moneys worth out of those ceiling speakers. Me personally I get a better listening experience with all speakers fired up. It’s awesome.
Yeah, I'm on the Auro-3D train for most content.
Great Content, thank you Techno Dad! I can highly recommend Auro 3D (Crossmixed), and Atmos (only some native English movies, unfortunately), it is still a hard and long way to go to have immerse Sound in Home Cinemas…
You are very welcome!
I appreciate your hard work making these videos for us the viewers/consumers can have the best Atmos experience. I completely understand this explanation which is the easier answer. Usually the easier answer is correct. Don’t let the negative comments get to you. Thanks bud.
Thank you, Cal!
You rock!!! Keep doing what you do.
Thank you!
Eh? You are technoblade's dad?
Hi! No, I am not…
I've been trying to get the link to your free Dolby Atmos Content and I do to the link and send my email and subscribe but I get no return notifications or email
Try these: technodad.biz/TDAtmosMP4 - technodad.biz/TDMatrixDA - technodad.biz/DAHeight
@@TechnoDad I got the file and here's how I did it, I downloaded on my laptop then downloaded on a USB stick and played the USB stick on my LG Tv mind you im running 7.2.4 but when I play it the front left and right heights play together when it goes to Heights for each side like I am playing 7.2.2 but when I test each speaker using pink noise through my Denon 3800 it all speakers play correctly, Also I have Dolby Atmos for Xbox and all its tests play correctly
New Update Files are working correctly if I play them from my computer downloads but once download them to USB or DVD they either don't play correctly or on DVD don't play on anything except what I made the disc on
i agree with what you're saying. But i gotta say after trying out what steve did at home theater gurus. it is a world of difference. With all do respect of youre saying about metadata carrying over from the studio, isn't that like saying that about stereo music too? Yeah they mix it optimally in the studio but at home if youve got your two front speakers jamed against a wall and not toed in you are not gonna get the optimal intention. Same goes with atmos i feel.
Hi! I totally get what you’re saying. With Atmos mixing, it’s more about where I’m placing the sounds in a 3D space and not what the sounds will sound like. Make sense? Atmos panning can be done visually. I don’t need to hear where I’m placing the sound because of how the 3D Object Panner is setup. I know that if I place a sound on the far left but half the distance from the front and middle of the cube, that sound will come out of the front wide left speaker. So the panning is all visual, which is different from a two channel setup.
I live for this. It's not drama, it's being passionate about getting it right. Rock on.
Woot woot!
@@TechnoDad I love how you take very complex problems and make them so duh! Obvious keep up the great videos.
Finally tested your Atmos demo and i have some work to do! I downloaded the file to a usb stick and connected to the xbox series x through a denon 8500h receiver in a 7.1.4 with ceiling speakers. It is cool to be able to check my speaker positions like this. Don't know why we haven't been able to test a system this way until now. The sound in the front does go up for me (ceiling speakers pointed straight down) but the speakers aren't directly in a vertical straight line, so i will have to align them perfectly. The combined overhead centre doesn't sound as good as it should. The phantom centre position between the ceiling fronts is perfect. My seat is not centered between all speakers but it still sounds great. One big difference though is in the volume levels between mains and tops. My tops are way lower. Again, i can adjust using this demo. I also have speakers set up for Auro, which i can test using this demo, but i reverted back to Atmos some time ago because i felt the localisation and precision of sounds was better over using Auro. My room is small, 12ft by 9.5ft with 8ft ceiling. I want to have a system that sounds natural and matches what the content shows. This is a simple way of hopefully helping to check the layout and if all is working correctly. It would be great if you could produce a demo with common movie effects, ie. flyovers, rain, gunshots, etc using all ground level and overhead speakers individually and together/groups. Don't mind giving a donation towards this.
This is not what meant when I searched for techno dad
Did you ever consider that maybe the Dolby atmos renderer shows you the top corners just for ease of understanding? Do you know what I mean?
Hi Davidde, I get what you’re saying and the interesting part is the bed channels actually have a globe or hemisphere shape. The issue with that is the only way I can place a sound at the very top is if the sound is directly above the MLP. If I try to place that sound at its highest point and half the distance from the front stage, it will not be at the top, it will be at a 45 degree angle. Does that make sense? A globe or hemisphere will limit where we can place the sound.
@@TechnoDad if I'm understanding that correctly it seems to make sense. I'm still so torn on what to believe. Like I said before I have tested both methods back to back. I didn't notice much difference at all. If anything mounted top speakers didn't seem to sound as separated as they should have been. This all makes me wonder though perhaps my whole setup is off! Lol
Do you believe this this way of Atmos matters under all conditions of a room? By that I'm mostly refering to the height of the ceilings and distance away from front/back. Love to know your opinion!!
@@TechnoDad also correct me if I'm wrong but DTS X claims it's designed to work perfectly no matter the speaker placement up top. Love to know your thoughts on X speaker placement. Keeping in mind their object simulator demo physically shows the top speakers where you believe they should be! Which makes sense right?
I want to know about the angled 📐 30° Auro 3D speakers…. Which ones you running and how you angle them
Don’t be sorry - you actually have a great point, though I personally believe in ceiling is fine too for majority of people. A lot of these other channels they are just making assumptions without actually understanding how atmos is done from the creator’s perspective like you have done. A lot of them also try to sound super confident and intimidate their way to being correct.
Everyone who isnt a Dolby Engineer is making assumptions here.
However, at least Technodad is doing Atmos mixing and playing the mixes back and not hearing what he intended which of course, sparked all this off.
All the conclusions that Chana is coming to now, I came to a couple of years ago (6 height channels in Front Height, Top-Middle and Rear Height configurations being optimal. Covers the whole ceiling while the Top-Middle can put sounds directly overhead)
I think a lot of people are resistant to what Chana is saying because they already have their speakers mounted in the positions recommended by Dolby guidelines and all the people who put in-ceilings into place, moving them is not easy. So any suggestions that they chose a less than optimal setup is rejected through cognitive dissonance.
@@FURognar I have had a 5.x.4 setup with FH/RH mounted on wall, not aimed and above the L/R towers. I think my Atmos experience greatly suffered by not having the TM. Channa is probably right about everything, but regardless I followed HTG advice and moved to studio spec with on ceiling aimed at MLP. Atmos in my room now is much more natural. Panning objects are noticeable& ambient effects fill the space. I don’t think anyone running 4 heights should take this advice and do FH/RH.
@@jayc5695 if you are doing an Atmos focused system, the HTG advice is very good, but you'll still get better coverage with 6 height channels.
But if you intend to use more than just Atmos, you need to investigate alternative setup guides.
@@FURognar I disagree
@@devilsdust473 about which part?
Im subscried to your e-mail how do i get your dolby atmos demos? Iv only gotten 2 of your videos. Let me know
Hi Marshall! Shoot me an email so we can figure out which ones you need and I’ll send you them directly - TechnoDad55 at gmail dot com
Channa De Silva aka Techno Dad IS Mr.Atmos.😂
Woot woot!! LOL!
But are they making 🤔 movies in atmos ?? They released HEAT in 4k but it's still 5.1 ??
My system is probably going to end up being 7.1.4 but I could make the Atmos .6, I have plenty of speaker wires running up into the attic above the theater but I'm not sure it's worth it. I'm not even sure what I'm going to build for Atmos speakers yet but I'm thinking maybe keep it simple. There is already enough complexity in the system, something has to stay simple.
From what iv read 6 speakers is optimal for atmos but also mainly if you have multiple seating rows in your theater. I currently only have 1 row seats and use 4 ceiling speakers and sounds great . My immersion lvl is great and have no complaints.
@@devilsdust473 I have three rows so maybe I should consider having six Atmos.
@@mfkhometheater7742 oh wow, I wish I had that much room in my theater 😕 in my opinion given that you have 3 rows I would definitely at the extra 2 to make it 6. 👍🏽
Awesome thanks.🤜
Hey Channa D my man. Hope all is well with you buddy.
Thank you Mike!
I really like the demo. first time downloading and playing a video and soundtrack. Great sound effects
Glad you like it! Here is one of my Atmos Music Mixes - technodad.biz/EatSleepTDAtmos - And here's a new one where I add rain and thunder sounds to a movie that was supposed to have Atmos but does not - technodad.biz/RMoonTDAtmos
love this! you are da man! hey are you able to convert songs to Dolby Atmos if you only have the mp3 file of the song that has already been mastered? or do you need the master of each individual track separated? in other words if I send you the mp3 of one of my hot grooves lol would you be able to work your dolby atmos magic on it? hahahahahahah 🤣🤣🤣🤣
I love my own atmos 5.1.4 setup (Pioneer AVR vsx-lx303 ) . I am considering your atmos calibration software (cd or digital) purchase. We are getting a lot of atmos streaming content nowadays , new series on DISN+, NFLX etc, but... compared to (4k) Blurays with TrueHD-ATMOS (or DTS:X) , these DDP-streaming-Atmos tracks mostly seem slightly underwhelming. I've heard stunning atmos at my home in films off 4k-blurays, but i am often disappointed at the atmos effects in new series like National Treasure Edge of History (2022-2023) and Willow (2022-2023). How do you feel on these DDP-atmos tracks in general or specific. (You may not want to slag off on specific titles, i would respect that) ?
Thank you for this! I don't have an Atmos set up in my home yet, but a decent 5.1 system. This video helped me make system correctly configured. The above my head portion you spoke of in this video was working perfectly for my setup.
Channa,
I really appreciate all your work mate honestly!!!!
Many of us have spent big bucks on the system and theatre rooms and both you and Joe I applaud!
Maximising what we have against all the elements.... Wow!!!
Loving your Atmos tracks so far.... Can a movie be done in the Atmos renderer?
Looking forward to grabbing the Spatial cd when the Magic bean comes out! 😊
Hi Ned! Thank you so much for watching and if you are planning on picking up our products, we thank you for that as well. Don't forget to join the Discord groups when you pick up the SACT and MB
@@TechnoDad
Channa will there be another 15% off promotion anytime soon or with the release of Magic Bean?
Last question... You guys have dropped off Auro-3d format? If So....
Can I ask why?
Cheers
I would add that if you mimic that layout, it doesn't require the speakers be placed in the corners or room boundaries necessarily. It just seems that the layout should have that cube shape for the movement to accurately replicate the movement within the Atmos renderer. Is that correct?
Dude when are you gonna speak on that Arcam you got? It’s been awhile
Oh man…had some issues with it over the past couple of weeks. Trying to figure out what the issue is…
@@TechnoDad Ohh ok that sucks man well I hope you’re able to fix it and thanks for the response. Your last video about it kinda got me hyped for it I can’t lie.
You have a demo disk to back it up yet ??
I'm running a 5.1 with dual subs and bi-amping with RP Klipsch speakers RP6000f, RP504c, R51m and two R-100sw. I'm a little confused about one thing and hopefully you can clear this up for me. Should I run my speaker setting as A or A+B. I'm running it as A right now. Thanks
Hi! What is your AVR model?
"It's in the computer...it's so simple!" 🤣 Yeah, baby! I don't know how many times I've suggested to commenters that they need to create a 3D cube speaker layout that the objects can move freely around in! Woot! And you're right...you might need to change your channel to AtmosDad from here on out! 😄🤘
Lol! Who would have guessed at 44 I’d be quoting Zoolander! 😆 thanks man! I know it’s a tough thing to hear that one may have cut holes in their ceiling for no reason…tough pill to swallow. At any rate, I hope shedding some light on this subject will get people to understand. We need to get you on the show again, soon!!
Hello and congratulations Can I download the files and share them on a facebook group citing the source? It is allowed? Thank you
Which files are you talking about?
@@TechnoDad atmos interactive 1080 and panic room
@@keyross7526 Yes, those files are perfectly fine to share!
@@TechnoDad Thank you very much!

Any idea as to what's the reason why many Atmos mixes only use the Top Middle speakers of your x.1.6 setup?
could be 7.1.2 static mixes?
🤘
You’re correct sir!
Thank you!
cool man the demo. Also, is it possible is create a 7.1.4 test tone for each speaker to check the level. because the internal avr test tone usually not accurate.
Yeah, that's pretty easy. How long should the pink noise be per speaker 30 seconds? 1 minute?
@@TechnoDad I think 30 second per channel should be enough time for level adjustment. thank you very much. By the way, I am wondering if you receive my email, asking your opinion about M&K S150 vs Martin Logan ESL for HT setup.
Thanks
Anytime!
Hey Techno-dad, great content!.
Unfortunately I am now getting confused in which decision to make before go through the task of rewiring/ positioning my four top front & rear speakers which are currently setup to the misleading dolby home spec.
I am currently considering the set-up in Steves video from theater gurus, where he talks about mirroring the dolby studio setup & bringing the overhead speakers in to 35 degrees.
My question is this, have you experienced listening to a peice of the exact atoms content, in your recommend set-up versus Steve's recommend set-up?
If so, your opinion on the comparison results would be a valuable one right now. Thanks
You are much better off following what Steve has to say as much as is possible, speaker placement is very important to get the best experiance
@@LceOnline yes, it makes perfect sense to me what he is saying.
Unfortunately I have had my set to usual Dolby set up for the past three years, & although it sounded ok, I just wasn’t content it the performance.
I am now in the process of re-running cable & patching up...just wish I knew earlier 😞
@@tonyoneill7031 likewise, I used to have the same problem a few years ago - spent some time sorting out better speaker placement and have never looked back it makes a huge difference - this video is misinformed, nothing within the metadata can correct bad placement.
I like what Steve has to say about matching your speaker layout to what they use in the studio...unfortunately, they don't use the same setup for every studio. The real thing to mimic is the cube of the Dolby Atmos Renderer to get the best Atmos experience.
@@TechnoDad that is what Steve said, in fact he points out what is wrong with the Dolby layout and the importance of correct angles and position so to get the best result. Your video in contrast harps on about metadata which is just the information on which a system reacts be it a good or bad one setup wise.
Technodad: If I were to use a Denon 6800H / 140 watt power receiver (coming 2023) with 15 year-old - 7.1 / 100 watt in-wall Proficient speakers - what could possibly go wrong? 😂
Hi! I would be worried about the wiring in the walls. Have you checked out the cables recently? I think that might be something to look at...
@@TechnoDad Many thanks for the quick response! Installation done professionally in 2008 and hidden behind drywall. Watching all your videos now and during the pandemic, the upgrade bug has struck hard! Want to upgrade from 7.1 to 7.2.4/6, so I guess I stick with a Denon 3800H or 4800H? (Run wiring externally from amplifiers to the 4 height channels).
Just don't turn it too loud I reckon. I find minus 20db is fine in most instances. Maybe minus 15 for streaming depending on platform..
@@stevenlawrence2232 Thanks for the comment. Marantz 5012 at 100 watt suits my space just fine. But now looking for an upgrade with height effects, in an imperfect room because of basement mechanical, without the need for yet another amplifier. Seems amplifiers are not inexpensive upgrades. One and done, at first blush, seems the way to go, but it seems that 125 watt speakers are now the new standard. SVS has a consultation service. I might just give them a call.
@@marvinabugov4579 when audioholics tested a recent flagship avr from Yamaha at 8ohms 9 channels driven it produced 50 watts. I think marantz have issued a recent guarantee of 75watts. If you like your 2ch stereo as well, sure use some nice high wattage mains for that, but manufacturer claims re wattage for multi channel are just that, claims. Most of us value our hearing as well 😉
The mixing sound engineer does not do his Atmos mixes in the blind and hope for the best. That would only take a couple of hours and he would be done, instead of the several weeks that it usually takes to produce an Atmos mix. (But judging from the Atmos quality from some movies it actually could be done in the blind to save time and money) He is using his Atmos speaker system to listen to the result and will adjust levels and 3D image positions to get the perfect sound image using his speakers. You will need to setup your own speakers in the same way to get the same sound image as the sound engineer had when he did the mix. The studio could be using speakers that have a wider spread angle or a higher grade of clarity or a higher ceiling position or other room measurements that doesn't match what you use at home and then you do not get the same sound experiance.
Trust me, they do not have the time to do what you say. They do what they can with the time they have. I've made Atmos mixes for a 3 - 4 minute song and it's taken 3 - 4 weeks. I'm thinking a movie would take 5 - 6 months if you wanted it to do it right.
Man I just watched your first downloadable video talking about how Atmos isn’t mixed at heights for 100% so the sound is so totally wrong for something like an aeroplane. You are so right. I’ve been saying FOR YEARS how underwhelming Atmos is. This is why. I bet it’s being mixed by lazy mixers that are not putting as much effort into it as you have and have not really thought about the real world implications have an impact to consumers.
Everything wrong with Atmos right there. It’s being done by someone who probably doesn’t care as much as you and is getting pushed to complete the mix in a set amount of time.
Hi Richard! Thank you for the kind words. Diving deep into creating Atmos is nothing I thought I would be doing when I started this channel. It is purely to find out what the most optimal setup is. And from a mixing standpoint, I would say that I would be pissed if I spent 3 months on an Atmos mix for a feature film knowing that 50% of the viewers at home will not be experiencing my mix at 100%. That makes me feel like my time and effort are wasted. Make sense? Anyway, thank you for watching and I’ll have more Atmos coming out soon. Consider being a Patron to get the sneak peeks and help me test out new files.
so why in the movies many people claim don't have much activity in the front wides bed channels or the extra 2 in the 6 heigh channels? so whats the point to increment channels when many sources are limited to 7.1.4 i agree with you for me need to be the metadata more than the any channels you have
This is a very complicated subject, but I will try to answer briefly here.
Many Atmos mixes are actually 7.1.2 "bed channel" mixes. Ready Player One being the most famous example.
A bed channel mix is effectively the same as an old school Channel-based sound mix. Bed Channels are permanent, unmoving Sound Objects which mimic the old 7.1 channel paradigm. In addition to the traditional 7.1 ground channels, it includes 2 unmoving Height Objects, usually placed into the "Top-Middle" position.
Those Top-Middle objects will activate 4 top/height channels because they image between them. A lot of people mistake those top-middle objects for 4 unmoving height objects, but its actually only 2.
When you play Ready Player One back on a system with 6 height channels (Top/Height Front, Top-Middle and Top/Height Rear) you will find that only the 2 Top-Middle speakers are playing height content. The front and rear height channels are silent. This is indicative of a 7.1.2 bed channel mix.
The same problem happens with the ground speakers. Since there are no active sound objects moving through the ear-level speakers, only the 7 bed objects play anything. Wide channels will be silent as will any additional channels like Center Surround speaker (Center Rear)
Shane Lee (formerly Spare Change) has a couple of videos talking about this behavior with static sound objects, which he can show you visually using the Trinnov Object Reader.
Search for "Shane Lee Wide Channels" to find the videos
Best explanation I’ve heard!
@@FURognar appreciate your answer and very informative! so this make me think that many dolby atmos are indeed old fashion discrete mixes! like the pseudo HDR transfers in many movies, a shame since i'm making a home theater with 7.4.6 with an emotiva bas mc1, i was thinking indeed to up to the 16 channel RMC1L for the front wides but as someone said, maybe too much money hoping to listen a couple of sounds in two more channels, again appreciate the time of answer i will look for the shane lee videos
@@FURognar Now i understand why in some mixes i really feel the objects aroud as the dolby atmos demos and others where the mixes only sounds like statics objects! could be good to have a database of movies even audio mixes with real audio objects
