Please don't burn your brains out. Your idea that it doesn't is spot on.

3 tips to think about to avoid any brain damage:

- speaker directivity
- (quasi) minimum phase
- wall density vs frequency

The reflective front wall is there mainly (but not only) for psychoacoustic reasons.

In short, The perception of the room for the engineer is very different than for the speakers. For the engineer it's quite a 'natural' space, for the speakers, it's very controlled. In many ways it's like they're in a different room.

Best thing is to actually ask Darius or the other Mastering Engineers working in these types of rooms how they feel. They're the ones using them 24/7. On GS you can find a few of them (Darius, Steffen Müller, Brad Blackwood for sure)

your description of what it does is exactly what Darius told me when I visited him a year ago.

I sat in the sweetspot for a brief moment as well so I could hear it myself and it really is amazing how natural it sounds.

Darius, geweldige studio, master je ook techno muziek?

And another question; how the heck do you finance this studio, it must have cost you a fortune..

Didn't know mastering audio was that booming business..

Great studio none the less, very close to my old school(Inholland) and work(Seabridges).

Hi,Darius
this is a great tread.i found everything i need.
Darius must be a Persian name,are U Persian?
if u are ,i am Iman Hojjat from Iran,can i speak with U in Persian language?
i am song writer and i have a studio for record mix and master in Iran.i work with many professional vocalist like Ehsan Khaje Amiri,Reza Sadeghi,Mohsen Yeganeh........,i have the best quality in Iran and i'l be happy if i could send some of my work to U and hear a feedback from U.

Regards

Ayous probably? I'm also building a Northward Acoustics designed studio and that is what is specced.

excellent !!!!!!!

Hi

I have already posted but it seems it has not showed in thread :-(

I reiterate, this is a fantastic quality and thoughtful build- a one off....

The attention to detail is exemplary and a wish you all the success fellas.

Its always a financial risk and worry but like myself its the attention to details that make a place, and your place has it !!!!!!!

All the best

Abachi is great, very light too. Only disadvantage is the grain on the cross cuts which is quite coarse (As you can see on the pictures)

Nice to see how you had the edges worked Thomas.

Just wondering, what's the design ratio of this room? Tried to figure it out but don't have enough measurements...

They need fine grain sanding, yes.

Weight is one of the main reasons we use that type of wood - it allows to avoid having to suspend 90kg to 120kg, but rather around 60kg-ish per unit.

Big difference.

The edges were done by DEMATEC. They're about a OCD as I am

It's likely a bad idea to measure from the simple plans posted in the thread as the dimensions H/W/L have been altered as well as geometry and half the treatment removed. Sorry... Can't post plans just like that. They are Darius's and Northward property.

FTB don't need follow the "golden ratios" or "louden ratios". Because they are cousins of the NE rooms and have shaped shells (how could one work the ratio of a shaped room using Louden for ex? Would not make any sense).

Hence very controlled rooms. Usually larger Mastering suites like this lose 60dB in under 150ms, often closer to 100ms for smaller rooms, almost linearly from 20Hz to 200Hz, although this can vary with speaker cut-off frequency & design etc.

We work the geometry until, looking at various frequency bands in particular the LF <150Hz, we get the behaviour we are looking for in terms of how the energy is spread in the room. This also helps optimize the treatment.

We do pay attention to the ratios of the outer shell, but it's not high on the list.

Sub-layer question for Thomas

First of all, I'm knocked out by the gorgeous design and execution of this mastering room! Here's wishing Darius every success in his amazing new space.

As I read through a build thread like this, any questions I may have are usually asked by other people and I remain a fly on the wall. However, in this case, a point was raised of interest to me, as I'll be to the fabric stage in a month or so. I'll be using Guilford of Maine FR701 (an open weave polyester). I've checked the fabric with strong light and there's no show-through potential from the fabric framing, so my question to Thomas is, why should you "use a proper sub-layer"? Thanks!

... maybe to stop potential airborne micro fibres from insulation... and surface irregularities can hide when upholstery is done.

Yes, hides small surface irregularities + dust and:

- Give a nice slightly padded looks (looks much better)

- Makes sure when you take pictures (especially with a flash) you don't see the structure behind through the fabric.
