I recently decided to upgrade my home studio by adding acoustic panels to the walls.

The idea of putting in a booth seemed to be a bit much for my space, and from the recommendation of another VO Pro, I took a look at the AudiMute line of products. They have a wide variety of panels, baffles and other sound-dampening materials. Different color options and even custom print pictures are also available for an additional fee.
