This is the age old question about acoustically treating a room, but it's not for recording as much as just a general practice room. I'm not too concerned about mixing and mastering as I don't think I can hear the difference much anyway. This is just for a nice little room to crank an amp in, or pound on a drum, slap the bass around without getting to much reflection. Some back ground;
Firstly. I moved into a new house with a small flat at the back (selling point as this will become man my cave aka jam room). The floor is carpeted and the walls are bare. There probably won't be space for a drum kit, but I will be doing my day to day jams and recordings in there. I don't want to burst the bank on acoustics but would still like it to be nice sounding. No need for calculators and getting heavy technical. What would you do?
Secondly. My drummer converted his servant quarters into a practice room for the band. As I understand it's also bare with no carpet. My ears just hurt thinking about it. He plays pretty loud and once the rest of band is added I'm sure it's going to be Hell in there. We will put in a carpet of coarse, but what next? What form of absorption is recommended. Should we build some bass traps?
Any suggestions are welcome.
