So, the studio is coming on a treat, we're working with the council and they're buying everything for us which is a HUGE help.
We've decided to re-paint the control room as we're all about making it SUPER comfortable at the moment.

But now, it's time to treat the room. It's quite a long rectangular room and we were wondering if there were any calculators that would help us nail where to put treatment frames.
The desk used to be on the left of that photo under that small white section. (A TINY window)
But, we decided to move it at the bottom to make the room feel bigger and we don't need it to be at the window as we're setting up a mic there and one person will always communicate with them at the window. If we can't handle it then cameras are an option.
Anyway, I would love to find out about some specific rules/get a calculator on where to place treatment.
