Hello everyone,my first post here. I use REW since several years,and I really like the Room Sim feature. It's really a great tool.I would like to suggest/request an additional option inside it. I think a huge improvement would be to have the possibility to visualize SBIR only,with the same 3D behaviour. I mean the possibility to move head/speaker in the room as already,but choosing to visualize only Modes,or only SBIRs,or both in action. Having also visualization of lines of SBIR path would be even a really cool thing. I have an homestudio for audio production/mix/master,already treated with broad and Low specific treatment. I can do the math for finding SBIR frequency and paths by myself,but seeing how good REW RoomSim is,it would save a LOT of time to have these features integrated. Maybe they are already integrated in REW and I missed,if so please let me know. Anyway,REW is really a cool software,keep up the good work guys.
