The impulse response decrease by 2db the original signal. Why?

Hello!
Is there somewhere where the program says the measurement delay?
I would like to know how to be able to adjust the delay time from a plug in.

And also know if the program calculates the distance in meters from the speaker to be measured to the microphone.



Greetings!

First step is to select one of your speakers as a reference when doing the measurements. Delays will be visible in the measurement information section but you can go to “Overlays” the “Impulse” tab. Here you will see your measurements and can measure the distance between the impulse peak of the reference speaker to the other speaker. First step is to generate the measurements.

Page 31 in the REW help guide V5.20, describes how to setup a timing reference.
