what? perfect acoustic treatment will benefit you less ear fatigue, you will be able to hear everything accurately, you will really enjoy mixing, and many more. besides, really expensive monitor speakers will be useless if you can't hear your mix accurately because of your poorly treated room.
i'm sure lots of you guys spend thousands on studio gear (not counting mics, and pres, and a/das, etc ofcourse) but you could've spent that money on acoustic treatments.
look at my studio gears
http://msxrecords.webs.comyou see vintage, old school stuffs, basic gears, cheap mics, DIY traps and absorbers...
my room is only 9x16 ft so i don't mix at LOUD levels. we can actually talk about something else while i'm mixing ( you by my side, or even at my back )
if im gonna treat my rear wall, mawawalan kami ng sala...
not all sound treatment were photographed or visible...
and treatment materials are just rockwool stuffs.... no big budget for fiberglass yet.
MAYBE AFTER ELECTION...
