I found it - > right click. Thx.

Hi I just updated and there used to be a button in the SPL/Phase window to generate minimum phase to view excess group delay in GD window? I cant see it, in Beta V5.4 106. I am used to viewing this as attached?

Great thanks so much John.

ah yes, sorry I should have looked more. Thank you. Will this output the NC or NR rating or do I need to calculate this myself?

Hi there, how do I measure NR with REW? Many thanks

OK thanks, I didn't know I needed to generate them, thanks.

Hi, just wondering why the T60 is greyed out here, is Topt the same?

Thanks a lot.

Ah I see, so then I calibrate Ch1, then remove loopback from Ch1 and put it in Ch2? And the reason we are doing this is because we need to calibrate the microphone channel?

Hi, I am just wondering about interface calibration is it correct that my microphone is connected to my left input 1 and my Loopback is connected to my right output 2 and input 2. When I go through the pages of calibration, it seems that the calibration input is been taken from the microphone...

Thank you, I got it now.

I'm sorry where?

Hello, I am trying to find the IACC measurement button shown here? https://www.roomeqwizard.com/betahelp/help_en-GB/html/iacc.html Thanks

I see, thanks, it's difficult to say which is which from looking at the GD and FFT graphs, so I am presuming all of the delays in the higher frequency range in the GD graph from reflections.

Thanks, so I read all this, so room modes can also cause fluctuations in the excess group delay, creating a non-minimum phase. So how can I tell when its a room mode or a destructive summed reflection?
