REW cal and limited bandwith

[Giancarlo Bellomo]

Good morning,
I introduce myself, my name is Giancarlo and I'm passionate audio diyer
I use REW with which I find myself very well but sometimes happens to me, especially with the latest versions of REW that during the calibration process, the audio band stops at 10Khz. Can someone help me to understand what the problem is?
Thanks in advance

What OS and soundcard are you using?

Premature cutoff at high frequencies can be a sign of a long buffering delay in the system, resulting in the input capture stopping before the sweep has finished playing out. That can be dealt with for measurements by using the acoustic timing reference feature and ticking the "Wait for timing reference" box on the Measure dialog when making the measurements, but calibration doesn't use a timing reference so it wouldn't help there. You could try reducing the Buffer settings in the REW soundcard preferences.

I tried to change the settings as you suggested but nothing changes. This problem only occurs with some versions of the

"Some versions of the..." what?

Have you tried selecting the actual output device rather than "Driver Audio principale"?
