Room treatment

Well, my new studio is totally screwing with my head.
I simply don`t have the time to learn the accoustics aurally, so I`m going to have to blow some dough on sound treatment.

I`m looking at bass traps, and sound dispersal. Any tips.

Also, the best position to make my set up longtitudinal in the rectangular room, is to have the desk and monitors sitting in a bay window.
Is this bad?

I know glass is highly reflective, however, I have wooden venetian blinds that cause an irregular surface, and they are always down.

Still a bad idea, or should I move the setup?

Not treated my room yet but i am very sure the best thing is to find out where exactly the problem areas lie first of all:

"If I were to do it I'd first measure the room using a MLSSA system and a measuring mic. I'd be looking at the waterfall plot to see where the problems lay in both the frequency and time domains.
I'd be looking at the overall and spot RT60 levels.

Then I'd start to think about what treatment mught be necessary. "

...from a thread that stuck to my mind...

...errr and always put the measurement mic up where your head would be whilst listening, at least i think thats something to consider...

steve, anything useful for you inbetween the mess i posted?

i'd like to hear your plans on the matter...

1.With a typical rectangular room, we usually start by treating the corners behind the speaker with bass traps. The mids and highs are also somewhat improved by treating these corners.

2.Next, we treat the specular reflection points at the side walls. With a stereo (2-channel) system, there are two specular reflection points on each side wall.

3.Depending upon the room's furnishing and window treatments, we would reduce the room's slap echo, particularly at the listening position and around the speakers.

4.Returning to bass trapping, we would treat the corners behind the listening position, possibly with the same size bass traps as the corners behind the speakers, but possibly with a different size.

5.Next, we may treat the middle of the wall behind the speakers to improve the imaging of most speaker systems.

6.Last, we might address problems on the wall behind the listener and ceiling.

As for the bass traps, I would start with rockwool panels in the corners. Panels should be covered with plastic in case that you only need to absorb bass or covered with some fiber which should also absorb the hi freqencies.

Well lot of this is helpful, thank you.
I have a number of restrictions.
My property is rented, so I can`t start putting in rockwall filled frames, and also, the room is fairly small.
So Foam sound treatment is the best option for me.
I was given a link to an amazing place here.

Which just about covers or can answer all studio design questions.

Also I have found a really cheap accoustic tile producer.
http://www.acoustic-foam.co.uk/
Who are cheaper than everyone, as they are a foam factory, rather than a sound company.

I am intending to bass trap the vertival and horizontal corners behind my monitors, and behind the control seat.

I will also add scatter tiles on the left and right walls (assymetrically) to stop any exponential reflection.

In the position directly behind the desk I will be fitting some broadband absorbers to the wall, this should aid in deadening the sweat spot.

I`m still not sure to do about the bay window, as I am going to write to the guys at studio design for suggestions.
I may end up getting some accoustic screens and putting these straight across the bay to square off the room, (well, not straight across, more, kinda jagged).

When it`s all done I`ll report back and let you know how it`s all been.

Once it`s done, Nightwatch Studios will be open for business!!!!

sounds really good so far. will you do any measurements then beforehand? i reckon that could save a few quid.
