Studio Rebuild!

[jbassino]

Done! A few details like the finish of the window and door....for the next weekend but im ready to start working! One month of non stop working!!
Hope you like it i have to take more and better pictures
Peace

Looking pretty cool, Javier! Very nice. I love the concealed lighting above the cloud. Great effect!

So how about doing a REW test, to see how it turned out, acoustically?

Thanks Stuart
Yeah the vibe is pretty cool, the pics doesn't do justice at ALL ( iPhone cam)

Rew test, will do! I will use my flattest omni mic fot now but we'll get an idea.

Peace

Fantastic Javier ! It really looks amazing…and you built it in no time at all. Congratulations !

looking good Javier.

[jbassino]

Thanks John and Simo!

Soon I'll take pro pictures with all the detales finished.


Here are the REW results. I have to adnit its pretty flat! what do you think?
And it sounds fantastic in here, i really like the new sound of the studio... it has improved a lot!

Can you post a link to the actual MDAT file?

Will do tomorrow

That pic had 1/48 smoothing by the way

There you go stuart!
I bet you can translate better than me all of these data.

Thanks Javier!

OK, overall it looks good, with a few issues that could be improved.

First, there's something happening at about 58 Hz that is probably modal:

It's not huge!: about 11 dB above the average, and it's at the very low end, but you could probably still damp it a bit more. My guess is that it is your first axial length mode, so probably some nice thick Volcan "Sonoglass Cine" on the rear or front wall would help. What are the final inner-leaf dimensions of your room?

Next, there seems to be a bit too much high-end absorption in your room:

jbassino-freq-responose-high-end-1.png

Once again, it's at the very high end of the spectrum, which isn't extremely important, but it is a rather big roll-off, hitting about -19 dB below the average level at 20 kHz. Can you still cover some of your insulation with plastic? Or maybe put more slats (randomly placed) on the side walls? That would help. Especially since the room is a bit too dead, overall:

jbassino-rt60-1.png

Your slats are clearly not tuned as slot resonators, so you could easily put plastic behind them, over the insulation (except at first reflection points) to help keep the highs in the room.


Then there's a strange dip in the mid range, which I haven't figured out yet:

jbassino-freq-responose-mid-range-1.png

jbassino-waterfall-mid-range-1.png

It isn't big (about 9 dB) but it would be good to know what is causing it. Maybe it is your speakers? Did you use your NS-10s for this test, or something else?

And finally, there's an early reflection at about 17ms that might be a problem. Not sure where that is coming from, but you could use the "string trick" to figure it out, if you want to. It's probably not a big deal, though. There are also some very early reflections at less than 1 ms: maybe vibrations in your desk? It looks like you have your speakers resting directly on the desk, not on stands....

Apart from those, it looks pretty good!

Thanks for your time Stu, let me do another test now that I have installed completely the sonoglass cine above the speakers.
My monitors are on my stands so that reflections are probably coming from the desk
I used a 414 for the test tho
I'll do another one soon with everything (furniture, decorations etc) installed
I really doubt installing more plastic behind the cloth since everything is put together and even tho my ears don't tell me it sounds dull, I actually had to roll off my tweeter after the measurement

Great! I guess it's just the angle of the photo that makes it look like they are on the desk.

Doing that roll-off is normal in most studios, and the extra absorption is right at the very top of the spectrum, so I don't think that's a big issue. I wouldn't worry about it, if the room sounds fine.

The overall RT60 is a bit low, but it is very nicely balanced: pretty flat across most of the spectrum, even in the low end. And to be honest, that's the way most people here seem to like their rooms: a bit dryer than the USA.

Yeah but it really doesn't sound as dry as you see it, the sound coming from the speakers are really focused on you and the stereo image is great
The big thing is that the sound is pretty even across the whole room, an issue that I had before, no low end on the couch for example, now that's been fixed
I really like how it sounds!

[Soundman2020]

Cool! I'll try to go visit you some time soon, maybe next week, to go listen. I'm working on a project not too far from you, (Jose Doming Cañas / Salvador, roughly), so next time I'm going over there, I'll give you a call and see if it's a good time to go say "hi". Do you still have the same cell phone number? Ending in 1528?
