sE Electronics Reflexion Filter Pro 9 Layer Acoustic Filter

Beautiful concert halls, gigantic high-ceilinged spaces, lofty stairwells with glorious natural reverb...capturing the sound of an acoustically-pleasing room can make a great recording truly special. But getting a good sound in a bad space is very, very difficult.

What if you're an artist recording at home? What if you don't have the budget for a properly treated studio? What if you move to a new house or apartment?

Even if it's a cardioid mic and is listening mostly to just you, it's still picking up reflections from your voice or instrument that are bouncing off the walls and coming back to the mic. The goal of acoustic treatment is to minimize the pickup of such reflections so your primary sound source comes through as pure as possible.

Some materials are good at absorbing or reflecting particular frequencies - for example, foam absorbs highs really well, but does nothing for lows.
