Hi Kim, and welcome!
Im after advice on room treatment for a room that is 2.4m wide x 3.4m long x 2.4m high
My advice on that room would be: DON'T! It has a square section, being 2.4m wide and also 2.4 m high, so you are going to have terrible modal issues in there. About the only possible way to make that room worse would be to also make it 2.4m long.
No amount of treatment can fix that.
So before you even think of treating the room, you should first think about how to change one of those dimensions enough that the modal issue can be minimized. Maybe a large, hard-backed cloud would do the trick.
Ive added a google sketchup of my room
The file is HUGE! It's over 35 MB! Please purge your SketchUp files before uploading them. After purging it is only 14 MB, which is still very large, so it's probably that the objects that you have imported are way too detailed.
The question now is, should i enclose the window to help with the sound?
The window seems to be at a first reflection, so yes, you will need to have some absorption in front of that. You don't need to cover the entire window, though. You could just put a large absorber on stand in front of the window.
any help would be much appreciated
I would also suggest getting a different desk, if you want to do serious mixing. That one has flimsy little light-weight shelves for the speakers, which is a bad idea. Speakers should never be on the desk itself, nor on shelves attached to the desk: the speakers make the entire desk vibrate, thus transmitting sound indirectly. Your speakers should be on heavy, massive stands behind the desk, and even then they should be decoupled form the stands with something like Sorbothane, Neoprene, or EPDM pads.
You should also fix the speaker / mix position geometry. Right now, your ears are at exactly 50% of the depth of the room (exactly half way between the front and back walls). That's the worst possible position, especially considering that the room has a square section. Your ears are right in the maximum nulls and peaks for all modes. Theoretically, the best position is to have your ears at 38% of the room depth, which means about 129 cm from the front wall. Your speakers are also show a bit too low: the acoustic axis should be at 1.2 m above the floor, but yours seem to be about 5cm too low. Not a big deal, but still worth fixing.
So those would be my suggestions. Then, once you have all that sorted out, measure the acoustic response of the room with REW and post the data file here, so we can analyze it and suggest what type of treatment you should be looking at.
