Hi everyone, I'm want to use one of my spare rooms in the basement as a home ecording studio. Does anyone have some advice what material to use at the walls and the ceiling? The German MusicStore Thomann told me to use the T.Akustik Basotect Element, which is an absorber reducing frequencies over 500 Hz. I read that another possibility is wood panels at the walls. I also read that it is recommended to use absorber and diffusor together. So I'm a little bit confused. I would appreciate any kind of advice.
