Me too. It is one of the reasons I still tolerate Waves. Another reason is Dorrough meters, and the number three being L3LL-Multi. Without those three, I wouldn't have a reason to use their products.

  3. one more for extra credit: the floor and ceiling shouldn't be parallel.
If you're getting decent noise isolation but aren't happy with the "boxiness," I'm afraid that is the best approach for vocals. Parallel surfaces create reflections. We build some really quick-n-cheap booths for our second mix stage (and in the process made the corners of the mix stage better for mixing) by just drawing out some random, non-parallel walls with masking tape and telling a contractor to build walls on those lines. They were probably around 20 square feet inside, so a /little/ bigger than your 4x4 booth, but not a lot. I tuned them for commercial VO which is ideally recorded pretty (but not completely) dead, but they actually worked (much to my surprise) for ADR in a pinch, which usually demands a MUCH bigger space. (Still not as good as our current ADR stage which is about 120 square feet, and that's still considered small when clients ask for room dimensions--although they don't say it sounds small when they don't ask and only hear it. But I digress.)

If you're OK with recording totally "dead" vocals (i.e. with no natural room reverb at all), you could try some cheaper options first:
  1. the 4" thick foam option, mentioned by a few on this thread
  2. build bass traps for at least two of the corners
  3. use foam to create non-90° angles in the 4 corners

These are all good and correct ideas. Along the line of better wall quality treatments.

"boxy" usually means "walls" are too close to the source...

Or wrongly built with cheap material that kills the tone too much.

Different dimensions but I have had similar problems. I'm assuming you're talking feet and not metres. There is no way a room that small is going to sound good. It sounds boxy because it's.... a box. You have equal room modes in two dimensions and the third dimension is close enough to 8 feet to create a mass of coincident room modes.

This could be your friend:

I've had far too many post-session cocktails to work out what your standing waves are but I wouldn't be surprised if you simply don't have enough space to put enough trapping in to get rid of any problems.

Sorry I can't be more positive but these booths are designed to cut out spill, not sound good.

Hi,
Foam doesn't do what you are after.
It's OK for taming some high frequency flutter, but your problem would have to be attacked with a different material; Rockwool, Roxul, etc.
Foam is pretty much decorative.

or even better as Rockwool is Basotect , with very interesting
capabilities , as seen here :
https://hofa-akustik.de/en/modules/measurements/

simple "foam" doesnt reduce the most problematic low-mid
and low frequencies in small rooms

Default vocal booth causing vocals to sound very boxy

basotect for fullrange absorbing needs to be pretty thick and that's expensive! mineral wool is very effective when you use the right density (look for 60kg/m3 = 0.5lb/gal (US)) but needs to be covered with fabric.
