Both excellent ideas. I went the route of Rich. Tex has a great idea too if you can afford a consultant.
If you google around there are stories of people tearing rooms out after building. Better to have a concrete plan on paper and not to wing it.
Thar pic was a room 15W X13H X 19L. Wierd dimensions but it sounds great now. Local studio mixers test their tracks in there now. Nice room. It is a film grading studio.
Easiest way is start with a room and pop a balloon... then see how deep the rabbit hole goes. I plan for commercial and resi installs, but dont do acoustical jobs anymore. Way too many man hours for too little money.
