Need Additional Acoustic Treatment & Setup Advice Please

Hi Guy's, We just m,oved into a new house with a abasement. The room I am starting with was already finished so I'm starting from that point. As you will see in the room, there is a small closet that has wood bifold doors. There is another door that provides access to a storage room, and another door at the top of the 3 stairs that goes out into the other part of the basement. This room is in the basement as well. It is carpeted and is drywall construction, including ceiling. There is one egress window in the room. I use this room for teaching and doing my own recording. My primary goal is to improve the acoustics of the room to make it better for mixing. Most of the recording will be VI's and direct guitars. Some vocals and acoustic guitars will be recorded but not that much (right now). I am not trying to soundproof the room. I really would like to keep the window un-blocked. If I need to treat that part of the wall perhaps it could be a portable design. For my budget, I plan to do this in phases starting with whatever is ost important. Preferably in $100-200 phases. With this being said, I am hoping to get recomendations on workstation setup and acoustic treatment recomendations. Please let me know any other info you need and I will get it for you. This is my first real attempt at treating a room. I hope I am doing this right. I've attached a "Sketchup" of my current studio room. I wasn't sure which file to attach so I attached both the .skb & .skp files.

Start by trapping the front corners of your room. You should move your monitoring position back from the wall so that your ears are about 89 inches from the wall in front of you. You'll need to cover all reflection points with absorption panels. The window to your right may be in a reflection path. If so, you can put a panel on a stand in front of the window when recording/mixing. Your rear wall is far enough away to treat with diffusion if you are up to building any. Trapping for this wall and the alcoves would be a good idea. You will need a 'cloud' trap overhead to kill reflections from the ceiling too. There are some great articles on the Realtraps site, http://www.realtraps.com/articles.htm the GIK site, http://www.gikacoustics.com/education.html and my pubs too http://www.jhbrandt.net/pubs.html.

Good and easy to understand advice John. Thank you very much!

John, I need to ask if there are other options to placing my seating position back 89" from the front wall? Reason being, I also teach in this room and this will take up more space that I would like it too. If there is another option I would love to learn about it.

This is only a 'starting point'. The 38% position in the room helps to minimize the disturbance effects of nulls and peaks in the wave patterns in the room. At 25%, 50%, 75% of the length of the room would be axial mode peak and null points and are to be avoided. Can you make your set-up flexible? fix it so that you can push it up to the wall when you are teaching and pull it back out into position for mixing. Cheers, John
