Settings in Preference "Analysis"

[Alpi]

Hello,

Since I regularly update REW, I wanted to ask whether my settings in the Preferences tab under “Analysis” are still correct.
I am still measuring with my Tascam US144mkII and a calibrated ECM8000 microphone. I use the acoustic time reference for measuring.



Thanks

All looks fine.

Thanks

But there are so many options. I think the important one is the checkbox for “Adjust Clock with acoustic ref.”
But what about the other options you can click on? I'm just wondering which measurements these are important for? For speaker development or...?

Best regards

Thanks, but maybe some things are very important to mention. I'll read through it.

Just leave your settings the way they are. You only need to adjust the analysis settings if you are doing something pretty advanced. You can read the Wikipedia entry on window functions and how it reduces spectral leakage. If you go to the impulse response and click "Window", you will see the window REW is applying to analyse your signal. You will see it is very generous and it starts well before the main impulse and ends well after it. You only need to worry about window functions if you are analysing a small slice of time.

In other words, don't bother. Leave the settings at default and worry about other things.
