Mixing in the tracking room?

[Ethan Winer]

Right forum, good question. As long as the room is treated to be more or less neutral, it should be fine for both recording and mixing.

Yes, there can be problems.

I have a larger room, but have 17 bass traps ranging from 4-6" of OC 703 in the corners, first reflection areas, ceiling, side and back wall. I did a Room EQ Wizard analysis at the mix position and I have a generally flat bass response from 20-300 Hz at the mix position and not terrible decay.

Still, when I have started to record acoustic guitars I still have a "tubby" sound, that I believe is from the still existing reverb in the room.

So, I am looking to create a recording space within my room that takes even more of the room out. Here's a post describing what I'm looking at.

You can always use Gobos for further refinement of your tracking.
Either diffuse or absorptive.

I have a question about absorptive Gobos.

In Bob Gold's absorptive chart below, most of the common absorption panels have close to 100% absorption in the 1000 Hz/2000 Hz/4000Hz frequencies. So, If I enclosed an area with absorptive panels, how would those frequency absorbing panels be interacting with the direct sound going into the mic. Would the mic be getting all the good stuff, while the panels simply make sure that nothing else bounces back? Or is there more going on?

Sorry for my ignorance. I just am now looking into Gobos and how best to use them.

It would depend on how you place them, the thickness, the size, the material... and what you are expecting i guess... not to mention what's on the walls and other surfaces around the area.
I would recommend thicker panels if possible; but the actual size [sq footage] of the gobo can effect the frequency it attenuates as well.

you need to take into account, other than direct sound; reflected, refracted, Diffracted (<-low freq)
Higher frequencies act sort of like light-rays... and are easy to plot out. (and easy to tame)
Lower frequencies (below 3-400Hz) act more like waves or blobs and can pass around small objects (compared to wavelength) like they are not even there.

So the larger the gobo the better, imo.
