I am not even sure where to begin on sound treatment for a room. I have been mixing in the following room. Green is the position of the desk and the listening position.
I have some Auralex foam under my monitors bu other then that I am not sure what else would be needed in the room. I have alot of issues hearing highs and low mids properly.
What do you feel are good DIY solutions to keep getting the room as good as possible for under $500
