[@Le.One.Siverss]

What was that material you mentioned in one of your videos? It was the fact that minerale wool when applied thicker or more layers become more reflective. in one of your videos you showed another material that was less kg/m3 so it was better to create basstraps. hope you understand what i mean. thanks!

[@warpacademy]

Hey hey. It was probably this video you're referencing: kzbin.info/www/bejne/iYTRaXt7qKxrqNE I expect the other material is Owens Corning pink fluffy fiberglass. We use that in rooms for deeper treatment when lower density is required. You can also use it behind higher density rock wool products for a dual-density / graduated density absorber, which is what we did. All the best!

Hey JJ. No surprises so far. We went a little bit over my expectations in terms of materials cost, but very close to budget. Tom was great in terms of researching alternative sources, comparing prices, and getting suppliers to price match.

@@warpacademy That's awesome - any general ballpark? like 25,000? 50,000? more than that? No worries if you don't feel comfortable talking about specifics - even rough numbers would be helpful - thanks:)

[@warpacademy]

Hey JJ. It's hard to estimate because we did the original build in 2018 and we're using all of that work for this build, then adding onto it. During that time there has been crazy inflation in building materials, so it's impossible for me to estimate how much that past work is worth in todays dollars. I would say under $50,000 though. Not including the monitors.

[@PetraKann]

The reason low frequency sound becomes more omni-directional is due to the higher wavelength. A sound wave in Air having a frequency of 100 Hz has a wavelength of about 3.5m. Halve the frequency to 50 Hz and the wavelength doubles to about 7m. In an average sized room the human ear generally can’t distinguish stereo imaging for low frequencies which is why only one sub woofer is needed and its position and direction in the room is less important. Human hearing is well attenuated in the 2kHz to 4kHz range because the rustling of leaves and twigs snapping are important sounds to pick up when you’re a potential meal for a lurking predator. Interestingly, human speech hovers around these mid frequencies so there could be an evolutionary and causal relationship driving this connection. I gave up trying to acoustically treat my home studio a long time ago. I made and inserted corner bass traps, hanging acoustic panels from the ceiling and various floor and wall coverings. For live microphone recordings these acoustic treatments help. In the end I opted for detailed headphone based post production, mixing and mastering and used common sense and compensation depending on the type of music being recorded and dynamic range etc. I would rather ask a drummer to set up their kit underneath a bridge or in a warehouse and use a few mics strategically positioned. The one area of live recording that home studios usually have great success with is vocals and recording acoustic instruments like guitar. A small room can work well in these circumstances. Cheers (The way you calculate the wavelength of a specific sound frequency traveling through air, divide the speed of sound in air (346 m/s) by the frequency (eg 100 Hz))

[@warpacademy]

Hey Petra. The frequency at which sound becomes omni-directional has a lot to do with the size of the baffle and the driver design as well. It's possible to create speakers that are not omni-directional in the low end (cardioid designs). Have you seen Kiis and Dutch & Dutch designs?

[@Alyag]

Wait... y'mean that a pair of Mackie CR3s haphazardly strewn sideways asymmetrically atop a messy desk in the corner of a cluttered bachelor apartment in the middle of a noisy downtown core ISN'T an optimal monitoring environment?! What the hell, Drew! Okay, okay... to their credit, the CR3s are somewhat passable speakers within the parameters of their price point. They are what they are. But I digress. This 'ere vid is packed to the brim with all manners of incredibly deep, utterly fascinating, mind-tickling (and unabashedly melting) info. Acoustics are a helluva science unto themselves, and one that I've always been warily drawn toward, albeit very much intimidated by, not the least because of all the, ahem, maths involved... and "maths" is my arch-nemesis.

[@SergeA-g5x]

Hello, Great video and information ! Question, if you were to do this but add Drums to the Room. What Changes would you make, to make sure recording the drums and playback is IDEAL. Thanks!

[@warpacademy]

Hey hey. Good question. This is a control room for engineering, not a recording studio. A recoding studio would have a completely different game plan. You'd have all the walls out of parallel for one, there would be no symmetry in the room, the room would be much less absorptive and would have much more diffusion. You'd still have an isolation shell, floating floors etc. But everything else would change for a live room.

[@SergeA-g5x]

@@warpacademy Thank You ! My only challenge is to have the drums in the same room as the mixer/production area. Meaning, when i am engineering I want the room to be ideal for that, and then when I am recording I want that to be ideal as well. So I want to have a room where I can do both. I do not want to cut the room in half and separate it . The drums would be towards the back of the room, and the mixer and production area would be more towards the front. Pretty much Control and Live in one room....

[@warpacademy]

Yeah, you can’t have both. I mean you can kind of get there if you look into “adjustable acoustics” but those are mainly for making a recording space (not a control room) more live or less live. My advice is split the room. Read Recording Studio Design by Rod Gervais. It shows you exactly how to do it.

[@dimigimusic4887]

And, please, could you explain in details tips and tricks regarding treatment of rear wall, which is, probably, the most important thing regarding low frequency absorbsion. Thanks in advance.

[@warpacademy]

Yes the rear wall is important for LF absorption but you can’t ignore all the other boundaries. The ceiling is just as important and an often neglected area for treatment. Also keep in mind that porous absorption gets less and less effective the lower the frequency. The lower the velocity of the air particles the less conversion you get into heat in a porous medium. This is why air gapping is often recommended as the particle velocity is lowest at the boundary where pressure is highest. At the boundary, you’ll likely want to consider another form of treatment like a membrane trap to handle low frequencies, depending on how well tuned you want your room to be in the low end and how much money and fuss you want to put into your room. Treatment on your side walls and ceiling - 6-12 inches or more is highly recommended. Make sure you pay careful attention to using the correct density of material too, as I mentioned in the video. As high density rock wool can reflect a significant amount of sound.

From the project it seems that the wall-mounted monitors are attached or very close to the wall, is that so? 6:32

[@warpacademy]

They are flush mounted in the wall, yes. Not touching the wall, but mounted behind the wall with the baffle just flush with the wall surface and a tiny gap from the cutout to the baffle edge so they don't couple. It's explained in much more detail later in the video. Cheers!

[@lk0707]

I ’ve been working with Philip Newel itself for last few months and just finished my new studio according to his design. Sound image in the room is on another level. Im surprised why didn't you decide to build wide band absorber at the back ? And only fill space with rockwool ? Are you going to fix woodwool boards on walls ? What fabric are going to use to finish walls ?

[@warpacademy]

Hey LK. That's neat you've been working with Philip. His book is excellent. We are not just filling the back end with Rockwool. In fact, we're not using much Rockwool in the treatment at all; it's too high-density for our depth. We're using layers of materials of different densities to create the desired effect, then covering them with acoustic fabric that has some stretch to it. It's the same fabric you see covering the modules in my 2018 room in the photos.

[@Royan1LtdCompany]

Very well explained and detailed description! There are way too many conflicting information out there and every room is different so your use of the facts and examples makes this video much more valuable. Would you use the sonarworks software for any "fine tuning" after your build is complete? Do you think it would be necessary?

[@warpacademy]

Hey mate. Thanks for watching and commenting. Glad you found it useful. The whole goal of such an involved room build is that no room correction should be necessary. We're avoiding all of the issues that normally cause problems by using a non-environment room design. The only issues I could possibly see using correction for are time-aligning the monitors, or doing very slight frequency response modifications to the monitors, but again that should be unnecessary due to the precision carpentry and selection of monitors that are extremely accurate and flat.

[@alexgarcialeal]

Awesome!

[@warpacademy]

Thank you! Cheers!

[@AndreiChivu47]

Hi! Great work and attention to details. I really want to build a room of this level as soon as possible. Could you share the measurement of the frequency response at the listening position after all this hard work? My current room deviates +-6db from the flat frequency target and has an almost even decay time throughout the frequency spectrum except the very low frequencies under 50hz. Do you think I can make mixes translate in these conditions ?

[@warpacademy]

Here's the completed room reveal: kzbin.info/www/bejne/jpeykJWqecqLoMU. We haven't yet finished final acoustic testing, but I'll be happy to share a video on that once it's done, and walk people through the results. That's pretty good if you're getting a +/-6 dB frequency response with even decay down to that low. What are your decay times looking like? You'd want to watch out for under mixing your sub-bass in that room, seeing as the LF ring time will be longer than everything else.

[@AndreiChivu47]

I can also upload the Spectogram for both speakers if it is of interest

[@warpacademy]

Sure. The waterfall is best with versions that are full range and then with limits set to 500 Hz and below. And ETC / impulse response.

[@jonathanbobo722]

Can you share the measurement of your frequency response you achieved?

[@warpacademy]

Hey hey. The frequency response is only a small part of the acoustic testing of the room. What matters just as much (if not more) is the ETC, the frequency-specific decay times / waterfall / spectrogram, and the T30. I'll definitely do a video sometime about all of those, so stay tuned!

[@HalcyonGuitars]

I wish there was a bit more info on the design of your front wall. I know from my own work that the physics of acoustics is mightily complex, but have found that the application of that knowledge is actually very simple. So I’m looking at your front wall seeing some pretty basic carpentry and wondering what is happening behind it. I don’t have the budget you did as that is the budget that went into my new workshop which is how I make my money, but I don’t mind spending a bit on my hobbies slash passions. Does the book you showed contain the necessary info to design and build something similar to your last studio with the DynAudio’s you showed some pics of? I’m putting my brain around getting the best out of my 27’ x 14’ mixed use room (with the unescapable 8’ ceiling) but my budget is 10% that yours was. For me there is enough space to lose a few feet on the front and back walls for treatment and a foot or maybe a bit more on the sidewalls…

[@warpacademy]

Hey hey. Those are good dimensions for a room other than the ceiling height of course. You could do a pretty good room with fairly low budget acoustic modules. Did you see my whole series on my channel (more recent videos than this) about how to build 4’ x 8’ wideband absorbers? Regarding the front wall, yes you can do it if you have decent carpentry skills and the right know how to the tolerances are tight so you need to be able to do precision work with a track saw or a table saw. Regarding the design, I could advise on that and a basic room design if you want to hire me. The books I talk about don’t show the details about designing a flush mount. Feel free to reach out if you want at vespers.ca

[@jeffpapis9474]

I may have missed it, but further detail on the speakers’ wall could be provided. For instance how the speakers will be secured to the wall; if the gap behind the walls will be treated; how thick and what materials will be used to construct the wall. Regardless, very good and clear intro to the topic. 👌🏽

[@warpacademy]

Hey Jeff. Thanks for the comment. I can provide some detail here. The speakers are not secured to the wall. They're decoupled on custom built stands. The cabinet sits on high density, specially loaded polyurethane bushings on top of the stand. The stand holds the monitor at the perfect height to fit just into the speaker holes. You don't actually want the monitor baffle in contact with the wall. A very narrow gap ensures no contact. The wall itself needs to be very rigid and very massive so it doesn't resonate. You'll want to use something nice looking for the facing (we used clear coated plywood). Then you'll want something very heavy and rigid as the backing, like MDF. You'll want to glue and screw the two layers together with a ton of screws. When you knock on the wall with your fist, it should be very solid. At the bottom of the wall, you'll want some absorption at the floor to front wall seam. We embedded ours behind the CNC logo panels, but you could also make triangular floor traps for this area with rock wool. Otherwise you'll have unaddressed bass buildup there. The ceiling is soft, so that's not an issue. Behind the wall you definitely don't want an open cavity; it would resonate. We damped the cavity with rock wool, while leaving sufficient space for speaker amplifier cooling, speaker control access, and access to the Panasonic ERV ventilation and air-tempering unit.

[@jeffpapis9474]

Cheers mate! Will do.

[@dougleydorite]

Serious question: have you considered the Kii three BXT option, which “advertised” to solve these issues for considerably less money, they are moveable, and won’t require a construction overhaul (transmission and treatment will still be needed of course) The idea being that the Kii three BXT provides cardioid response VERY low and the line source sound emission will solve the floor bounce issue. Curious what your thoughts are on this

[@warpacademy]

I would certainly be keen to try some out. Except a pair of them costs more than my entire studio. Prohibitive price point. But interesting technology. I’ll be keeping my eye out for them.

[@dougleydorite]

@@warpacademy I see. I was thinking your studio would 4x the price of them

[@warpacademy]

Definitely not. This studio build is actually quite economical compared to a pair of Kiis. And, although they are said to be very directional, I'm not really sure if I'd actually like the sound of them. They look great, but I wonder how they actually sound. I know a few folks using them for mastering, but not mixing.

[@dougleydorite]

@@warpacademy I’m curious on how you are pricing your studio… if I get a place/facility/land here in Washington, it’ll cost $750k for something decent before even starting the studio build portion of it. Maybe I could find a place that has a big shop for $500k… but it would be dumpy

[@warpacademy]

Hey Dougley. Take a peek at part 1 of the series: kzbin.info/www/bejne/rYjYgoyiqtOGrJI. This build is in the double garage of a house that I bought. So there wasn't an incremental cost of a dedicated studio property. That was key in my decision. We just repurposed the garage, which worked out great as were able to build the isolation shell on heavy concrete slab. There are renovation costs, associated with building the shell and interior treatments, but much less than building a ground up structure. Also, our isolation needs are far less than a studio in a typical city and industrial space so we didn't need the massive structure that would normally be needed for isolation.

[@farid6491]

what is the relation between density and depth? how to calculate?

[@warpacademy]

Hey hey. Great question. This is a pretty substantial deep dive so I made an entire video on density and depth and porous absorption here: kzbin.info/www/bejne/iYTRaXt7qKxrqNE There is an included calculator where you can estimate the gas flow resistivity of rockwool if you have the density (for products of the same fiber structure). Cheers!

[@11219tt]

Any insight on why mastering studios generally use free-standing full range speakers and not flush mounted ones?

[@warpacademy]

Hey hey. In general they don’t. Check out the rooms designed by Northward Acoustics, Newell Acoustical Design and Wes Lachot Design Group. Those are the guys who really know what they’re doing and they all universally build rooms with flush mounted monitors. The only time I see free standing monitors in a professional studio is when they put near fields on the console which allows you to work in the close field. But they will have flush mounted mains. I do occasionally see speakers on stands in professional rooms but they’re usually for Atmos or surround formats. Also, there are a lot of people out there, including mixing and mastering engineers, who don’t fully understand the acoustics involved or who don’t want to go to the investment and build complexity of doing a flush mount.

[@11219tt]

@ I'm wondering because Abby Roads, airshow mastering David glasser, piper Payne, Bernie grundman and Bob Ludwig all has speakers standing and not flush mounted.

[@warpacademy]

@@11219tt Yeah, I do see this. To that, I would say that mastering engineers aren't acousticians. There's sometimes overlap in knowledge, but I've been really shocked by the amount of audio engineers who don't actually understand the physics involved. It's also possible there is really deep trapping in the boundaries surrounding the speakers, which you may or may not see in photos due to it being fabric covered and looking like a wall. LEDE room design, for example.

[@11219tt]

@ another thought I had is that maybe certain speakers are built to be freestanding and there might be more data available to place them away from walls. So without the proper acoustician who understands the build of the speaker it may be easier to go off of the manufacturer's recommendations. For example Airshow uses Dunlavy SC-5 and iv's. Dublavy built the speakers with stepped fabric baffling on the front to avoid some of these issues (from my limited understanding). So maybe flush mounting these would affect the sound. Interesting topic considering it's a discussion between the acoustician and the speaker manufacturer, which may or may not be happening.

[@warpacademy]

@@11219tt Hey hey. Good thinking on that. You're right that some speakers are not designed to be flush mounted. Rear ported speakers cannot be flush mounted as it blocks the port, unless you use a sub to highpass them. And then you have designs like the Barefoots or Focal SM-9s with side cabinet mounted bass radiators. Those also cannot be flush mounted. Let me get one thing perfectly clear though: you cannot get around the physics. There is no amount of "manufacturer data" or special design (aside from cardioid models like Dutch and Dutch 8C or Kiis) that can contravene the physics. The physics are basic. When the wavelength of a frequency exceeds the diameter of the driver producing it (like with bass where the wavelengths may be 30 feet and the driver is 10 inches) then that frequency will radiate more omnispherically. When that happens, you get rearward radiation that will bounce off your front wall boundary and incur destructive interference with the direct signal that will severely compromise (IE ruin) the low frequency response of the system. This happens 100% of the time, and there are no exceptions just like there are no exceptions to the law of gravity. However, there is a lot of lack of true appreciation of the physics, as well as people who seem not to care about the low frequency response of their system.

[@KeyfloMusic]

Can I build a box to put my speakers in and push the as close to the wall as possible? Can that help with SBIR? I cannot flush mount unfortunately.

[@warpacademy]

Hey hey. That’s not going to help. Just push them close to the wall to get that rear reflection as close to in phase as possible. And place acoustic treatment around the speakers.

[@KeyfloMusic]

Sounds good.

[@rcook2608]

Rockwool rep told me anything thicker than 6.5” becomes redundant with safeNsound unless there is a minimum air gap of 1”. Cool insights

[@warpacademy]

Hey hey. Thanks for adding in that comment. I would be hesitant to place much stock in what Rockwool folks say about anything related to acoustics. They are far from experts in this field as their focus is on insulation aspects of their products and perhaps some architectural acoustics (noise reduction for interior walls, NRC etc.); not control room acoustics. From a physics perspective, the more porous absorption you add the more effective it will be but you need to mind the depth vs. density consideration, and reflectivity. Air gapping deep rockwool or fiberglass is not necessary. The only reason you'd do it is if you're concerned with budget. A better move is to fill the cavity with lighter density fiberglass rather than leave an air gap. That's what we did with the rear wall modules in my control room (3.5 feet thick) and we have a ruler flar low end down to 26 Hz. Check out this deep dive into porous absorption: kzbin.info/www/bejne/iYTRaXt7qKxrqNE.

@@warpacademy Hi thanks for the reply. I’ll check the book out, luckily for me I have studio designers/engineers on the project that are specialized in the field. Bass trap details have been especially interesting, as our atmos mixing room varies from our main control room. I’m sure you have experience with foil faced fsk acoustic insulation, do you know if there’s any difference (generally speaking) between faced and non/faced products? I’m using leftover Owen’s Corning 706 and 703 fsk for reference on a few areas in some build outs and am curious if the foil makes any acoustical difference. Thanks 🇨🇦

[@warpacademy]

Hey hey. The foil will definitely make an acoustical difference. It will reflect HF where an unfaced material will not. It will also act somewhat like a range limiter / membrane, because you can't blow through foil. FSK is generally used for a front wall where the back of the room is mostly absorptive, so you get some acoustic queuing from the HF reflectivity. Take a look at this room: kzbin.info/www/bejne/gmOWfHudgp6ah80. You can also use the FSK as the front layer in a bass-oriented treatment, but I wouldn't do that. I'd use unfaced 703 as the front layer, and wrap it with GOM / Duvalex Anchorage fabric.

[@roderickmims4802]

Can you please explain the shape of the room? I notice some engineers don't have rectangular room but more like an octagonal room. What's the actual name of a room shaped like this one and why some room are design like this?

[@warpacademy]

Hey mate. Happy to answer that for ya and it's a really good question. Some rooms use an RFZ design (reflection-free zone) which use shaped shells. These angled boundaries are designed to reflect sound away from the listening position. However, they're much more complex and costly to design and build. In our case we went with a rectangular isolation shell and used extensive interior acoustic treatment and an angled front wall to handle reflections. There are absolutely no strong reflections at the mix position in this case either. So it's very much like an RFZ. This room design is called a "non-environment room", originating from Tom Hidley and later used by Philip Newell in his book Recording Studio Design. The concept of this type of room is to use a hard front wall with flush mounted monitors, heavy acoustic treatment on all other surfaces except the floor, and some reflective treatment on the back wall for scattering a bit of live sound back into the room. Cheers!

@@warpacademy How costly can they get? Can you possible get someone to build it?

[@warpacademy]

I would certainly get someone to build it. Designing music studios is one thing, but building them also requires a very specialized skillset. You need to understand more advanced constructions concepts associated with acoustic materials, decoupling, hermetic sealing, floating floors, and next-level finishing carpentry. I would not attempt this unless you're going to hire someone who does that type of work. I would say those types of rooms range from $100,000 to $500,000 USD depending on how crazy you go, whether you're renovating an existing space or purpose building, and the room dimensions. That's a rough estimate.

You’re most welcome.

Dare I ask what the budget was?

[@warpacademy]

Of course. We're currently in the final stages of the build, so I don't have an "all in" number yet. My closest estimate is $55,000-60,000 CAD, not including monitors or other equipment in the room.

What’s with the noise on your vocal?!

[@warpacademy]

Weird recording chain issue. This was a new configuration for me and took some work to get the bugs out with the interface. I tried some de-noising on it, but it was too watery sounding and heavy handed, so I left it mostly intact in the video. Sorted it out in future ones.

[@Studio22mix]

I don’t know but all those acoustic treatment videos makes it look like it’s hocuspocus or almost impossible to get your room sound decent. However with some absorption panels, the right speaker placement and tuning your speakers with some room correction software can give you great results. All it has to do is make my mixes translate to different speakers. The few flaws in the frequency range are easily adjusted when you know your room. Unless you’re mixing daily for the big billboard charts and every minute waisted counts then you’ll have plenty of money to outsource the design. For most of us the only thing that matters is good translation and knowing the flaws of our room. Building an acoustically perfect room will get your 10.000 dollars budget drained pretty fast.

[@warpacademy]

For sure. It all depends on your goals and budget. You can do a lot with much less treatment and less of a budget. You can DIY fabricate yourself some great modules, inexpensively, like these ones I show how to build: kzbin.info/www/bejne/e3TEq3qwqtmejJo. A few of those in your room at the right places and you're already on the right track. What this room is though, is a professional control room. It's not a hobbyist room. We built it for around $60,000, which is quite good for the results we got. It's a high caliber professional room that's used day in and day out for mixing and mastering for projects where time and results really matter. This type of room is not for everyone, but it certainly is achievable and can be done in a garage at home if you have the expertise and skills. Cheers!

To express this, you don't need to put on headphones as big as those of the Lady of Elche, you are not a radio announcer receiving instructions through them.

[@warpacademy]

Like you'll see with virtually any podcast show, I live-monitor my mic audio through headphones as I'm recording. The headphones I use are the same ones I use to reference when mixing and mastering. They just happen to be large because they're exceptional full range headphones.

must be nice being fucking rich

[@warpacademy]

I spent less on this room than most people do on their car actually. It’s not inexpensive but it’s also not an unmanageable amount if you consider it a business investment. It’s an income source for me so it makes sense.

[@ZVUCHI]

How it work this room ) kzbin.info/www/bejne/a4ivc4qnqpyXkMU

[@warpacademy]

That room has a nice shaped shell design in both cases with non parallel side and back walls. But the example on the left shows a highly reflective back wall. The example on the right shows heavy use of diffusion to scatter sound back into the room. My room design has a highly absorptive back wall with 3 feet or more of porous absorption and slats on the final layer of modules for scattering some sound. There will not be a large direct reflection like they show in the video because that energy will be highly attenuated.

[@ZVUCHI]

@@warpacademy And what about all the other walls, are they also filled by 3 feet?

[@warpacademy]

No. That’s not necessary. 1-2 feet depending on the boundary.
