The facts are that if you are recording in your home or in a studio, you are going to need acoustic foam. They dampen unwanted reverb, absorb sound, and make editing a bit easier in the long run. Wedges and acoustic foam isolate your music and curb the unwanted escape of noise. These are essential for people who live in close proximity to other people and want to be considerate with their noise level. I strongly suggest picking at least a few of these up, even if you are recording in a closet! It's a MUST HAVE!
