Hi, Is there anyway to set R.E.W. to analyse the sound after let's say 5ms? I wanna measure, some reflection panels and i want to completely exclude the direct sound of the speaker. First reflection is at 5.2ms. So is there any way to get "all SPL" after 5ms? Thank you

Yes, position the impulse response window so that it covers the region you are interested in. Typically you would set the window ref time to the time of the reflection and set the left and right window durations to span the area of interest. The window will likely be fairly narrow which will mean the frequency resolution is quite coarse, the resolution achieved is shown on the IR Window dialog.
