I have a large amount of not-broken-down cardboard boxes that I need to hang onto, and they are piled just outside the door of the small basement room I am trying to use as a (admittedly incredibly primitive for now) recording room. That room seems to have some echo that is probably not good for my recordings and I'd like to reduce it or eliminate it for free or very close to it.
I wanted to try moving the boxes into the studio to see if that would do the trick. What I've seen online is that (broken down) cardboard affixed to walls can help with echo, but I do not want to break these boxes down, as I need them eventually for moving. (Yes, I can always get more boxes for free but it's a hassle and not always the cleanest thing and these are exactly right for moving, so I'd rather just keep them).
Any thoughts on whether this should work? I could do the experiment but I'd rather not attempt it if it's going to be futile.
