Acoustic Treatment for small recording/mixing room

[Anthem]

I'm going to be moving to a house where I will likely have to use a 11 x 11 ft. room to record vocals and acoustic guitars. I have already made bass traps from mineral wool covered in fabric and I have enough for all vertical corners and much of the horizontal corners. I also have enough Denim insulation to make super chunk bass traps for the vertical corners. I am considering using super chunk bass traps in the vertical corners and the 4" mineral wool traps on the horizontal corners and then attaching the extras to the ceiling. Will this make this room usable for recording acoustic guitar and vocals and getting good recordings??

Also, in a small room isn't it best to sit with my back to a treated corner to record guitar to avoid the room nodes that would be most built up in the center of the room??

Any advice is greatly appreciated. Thanks!

Anthem, in a square room, you do need lots of Bass Traps. The more the better. The result will be quite a dead space. Such an acoustic makes very clear recording of vocals and acoustic guitars.

The best place to record an acoustic guitar in the room is where it sounds best to a microphone. The most reliable way to find the sweet spots is to record the same bit of music at the likely locations, listen back and chose.

This might deliver a better understanding of modes

Some pointers.
The lowest and stronges axial mode, double strength in your room, creates a massive null in the room centre. There will be a black hole at 51Hz.
On the other hand 102 Hz will have a peak there.
At 38% of a dimension, the modes kind of average out , this can be a quite well balance location.

So in a room 10 ft. by 10 ft, if I use bass traps and sit about 3.8 feet away from the wall or corner with my back facing the wall/corner I should have a decent sound?

[DanDan]

I guess this would be a good place to try. Good modal distribution, clear of the centre, far from early reflections. Sorry if I was confusing about the centre earlier or in the other thread. Acoustic guitars have a resonance at very approximately 100 Hz, the centre is likely to be quite boomy.

Thanks for your input!! Here's another option. What if I build a huge superchunk bass trap in one corner and then treat the walls on each side of the bass trap too with denim insulation (ultratouch insulation made from denim) and then bass trap all the other corners with my 4" think mineral wool bass traps and then face that corner to record vocals and acoustic guitar like a isolation booth? Will that work to give me a dry but accurate sound and keep the problem frequencies from getting built up in the room??

[DanDan]

Try it. Record it and see which way comes out best on the mic. Huge superchunks are great. 4 is better, but one is still great. There is no symmetry issue here.

Good I'm pretty sure I have enough denim insulation to superchuck 4 vertical corners and then I'll use the remaining 4" mineral wool bass traps for the horizontal corners. Maybe this small room will sound good after all. Should I still get the reflexion filter??

[DanDan]

I haven't tried one and to be frank, I wouldn't bother.
Commonly the closest and thus loudest 'honk' reflection comes from the ceiling.
If your ceiling is low, I would definitely have a 'Cloud' there.
Spend the money on that rather than the very very small, with no overhead, RF.

What about 8 ft. ceilings? SHould I put a cloud over the area where I'll sit to record and mix?? And is a 4" cloud of denim insulation enough to absorb this bass frequency??

[DanDan]

Yes, always. Please do some study of the basics before asking questions.

Hey Dandan, I have ancestors in Cork Ireland!! That is cool!

[DanDan]

Small World eh?

Here's a question. If I'm using a miniflex 2 mic inside an acoustic guitar and I face a corner to record will the tone of the guitar be affected by the room acoustics and the bass coming back out of the corner even though the mics are inside the guitar??
