I just spent the last two weekends building all my bass traps and absorbers, and was just wondering how long it takes to get used to a new room?
Imo/e this will directly relate to the experience of the engineer .."treating" a room is just solving one part of the puzzle of getting what you hear in your head to translate to the outside world. An experienced engineer can adapt quickly and a novice will take a longer time. Considering the treatment is proper, I would start by doing some critical listing to music recordings that you are very familiar with. gl
