Cal file truncation upon import

[Tom Holman]

REW Cal files truncate upon import




Cal files made with REW soundcard calibration and mic cal truncate when importing at a lower frequency than in the imported file.



Example file

* Soundcard Calibration data saved by REW V5.31.3

* Source: Scarlett 2i2 USB, no input selected, R, volume: no control

* Format: 512k Log Swept Sine, 1 sweep at -25.2 dBFS using a loopback as a timing reference

* Dated: Sep 24, 2024 10:17:33 AM

* Note: 9_24_new

* Sample Rate: 96000

stops importing as read by reading the cal file in the REW cal at 5.166 Hz.



Mic files do same truncation though at 2000 Hz (many fewer data points).

What am I doing wrong?

 

[John Mulcahy]

Could you attach the cal files? You may need to make sure the extension is .txt, or zip them and attach the zip file.

 

[Tom Holman]

I tried .txt and zip but they had the same problem. They import frequency and values but then stop around 2k for the mic cal and much lower for the sound card cal. OTOH I see hf response of the sound card cal plotted when it is used, so something is being masked but used? How odd.

Attached please find the files for your examination. Oops I find .txt and .xlxs file are grayed out from attaching. What do you suggest I do.

Thanks very much for everything.

Perhaps just putting the whole file in text here might work. Here is the miccal file.

That works fine for me. You can email file examples to feedback@roomeqwizard.com. Can you post some screenshots of the truncation you mention?
