My personal production studio is in a brick backyard cabin. It is a rather small 9m² room, measuring roughly 2x4.5m. Those measurements, the position of openings, and my own preferences leave not much choice in how to organize space.
I use this studio primarily as a production room; i also record voices, mostly spoken, and low-volume acoustic things. I have no plans to record anything loud like electric guitars or drums for example. Thus i tried to find a simple and effective way to acoustically treat the room, while preserving most of its surface.
