I've recently upgraded my recording system. Unfortunately the improvements in the signal chain have highlighted more and more the sound of the room I'm in. The other night I tried singing under a couple of futons with really good results. With a touch of reverb the vocal sits in the mix much better and the fans on the computer are no longer heard. Alas, I can't play the guitar under there, so I was thinking of building a small booth, say 3 x 5 x 7 feet, and hanging the futons on the walls to create a deader environment in which to track. Some degree of soundproofing is a bonus, but my main aim is a more neutral acoustic to take and treat with effects. Will I just be swapping one duff sound for another?
