1) how to include the room resonances from the Room Sim window when I am setting EQ filters in the EQ window. Does that happen automatically. I can see "resonances" is grayed out on the menu below the graph. See photo 1.
2) I have noticed that adding a room curve with 2 db of bass boost gives a very different EQ target curve compared with 3 or 4 db. But also does not add a filter to address that dip at about 46 Hz. Any ideas how to address that? See photo 2.
The predicted modal frequencies can be shown by entering the room dimensions in the Modal Analysis section and selecting Show modal frequencies in the graph controls.
REW can also analyse the impulse response and detect resonances within it, for that use the "Find resonances" action in the Modal Anlysis section. It will populate the Resonances section with those it finds and any you select from the list will be shown on the EQ graph. Multiple selections can be made. There's more about that in the EQ window help.
