I'll guide you to make the best of your room treatment. Provide a comprehensive excel to estimate some room parameters (such as TR, EDT, C80, and D50). Will teach how to measure your room according to ISO 3382 with REW and compare experimental results with simulation. I am a Brazilian acoustic engineer with expertise in room acoustics, collaborate over 20 projects, including some for people working in ODEON. I can make your room simulation from the stretch: Bonello, modal response, SketchUp a model and run in a room simulation software.
