Watch this video on how a guy created a vocal area in his bedroom $30 worth of stuff you can get online and at your neighborhood store (cheap Uhaul moving blankets and some hanging hooks). You can REALLY hear the difference!
Here’s a link to the YouTube Video: http://tinyurl.com/BaffleVideo
He uses two blankets, a quilted moving blanket which you can buy for $15 at http://tinyurl.com/QuiltedBlanket, and under that a regular furniture pad, which you can buy for $8 at http://tinyurl.com/FurniturePad. You’ll also need $6 worth of hooks from Home Depot or any hardware store and a set of shower rings, which you can also get at any Wal-Mart for a few bucks.
If you don’t have a way to build something like this and you have a walk-in closet in your house? Record in there! You’ll be amazed at the difference in quality you can get in a closet full of clothes.
