this is a drawing of what my room looks like, as you can see it's not your average. I've looked online for similar rooms but couldn't find anything. The only thing I learned so far is "bass traps in every corner" lol

The drawing is somewhat out of proportion but the numbers are correct. All numbers are in CM (centimeters) Walls are made of concrete. My primary aim in this room is to produce music and mixing. The small booth of course for vocal/(acoustic) guitar recording I Dont like things superloud, but neighbours are never home so every now and then I'd like to crank up the volume, but its not a must. My budget will eventually be around 1000 Euro's So my question is 1.How do I treat the main room 2.How do I treat the vocal booth please, help me out. Thanks
"The only thing I learned so far is "bass traps in every corner" lol" Actually that is a marketing mantra...not really something that someone should "learn" and hold on to as there are so many things that we can learn that can contradict that statement. edit: corrected a typo, nothing changed in the content

Thanks for telling me that! So far as soon as I entered an "acoustic treatment" topic, the first reply would be "make sure you set bass traps in all corners" What are downsides of having bass traps in all corners? I can think of "less low frequencies that will bounce of walls and will cancel/double" but isnt that a good thing?
I don't know about a downside what I do know is that many rooms can function as designed without what is called bass traps but is more correctly called broad band trapping or broad band panels.
I believe a broadband panel placed in a corner then becomes a bass trap. Most bass builds up at corners so you trap a lot of them in there :)
thanks for the replies guys. Im pretty set now on what and how I wanna construct everything. question tho. What is the difference between an absorber and a bass trap?

As a "trap" is isn't, as I am coming to understand them, what it is. What it is, the word "trap" is becoming is a generic term. When people designed things, like five foot deep walls or hanging baffles in the ceiling or behind acoustical wall panels in walls, these are the bass "traps" that folks refer to. Everything else is just a marketing term :) Granted vibration moves to the edges of the panel so installing a broad band panel, or what is commonly called a "bass trap", is the obvious solution. But it does not go down [broad band] to the absorption of the 20-30Hz range that a five foot thick wall will. That's my thinking on it as of today.
that does indeed sound intresting. Im going to read more into this...
First you need to have the correct room measures before anything can be done. Measure the room again as accurately as possible and post them. It's VERY hard to help you when we have to guess the correct angles etc. I can see that you have an odd shaped room but theres a good chance it can be used for your advantage with minimal treatment. So provide us with an accurate layout and more help will come.
