"Change Cal" button missing

[DeepSOIC]

Hi!
How do i change mic cal for an existing measurement? According to the docs, there should be a "change cal" button on the flap below a measurement on the panel on the left, but it is missing for me in v5.20.14 and 5.20.13

Go to the Preferences menu and select 'Delete preferences and shutdown'. Then uninstall REW using the uninstaller program in the installed directory. Then reinstall REW using the latest EA release.

did that, to no avail.

I have played with it a bit more, and i do see the button for some other measurements. I consistently do not see it for multichannel-averaged measurements. The "my mics" one on the screenshot is indeed a multichannel one, but the "dayton mic" is not supposed to be.

I would still like to change cal for the multichannel one though...

There isn't an option to change cal files for measurements saved from the RTA or for multi-input and RMS averages. In the case of averages every input to the average could have had different cal files.

please add it if possible. I understand that one could need different cals for each mic, but my mic array has mics similar enough to use a single cal file for all of them.

I'll do math now then. Or maybe remeasure.

If all inputs used the same cal fie you could import the old and new cal files as frequency responses then divide the new cal file by the old and multiply any averages you want to update by the result. Providing a change cal button would mean retaining the cal files and individual responses for each input in the average and providing a means to change each of the cal files for each input, which would be a lot of effort for a fairly rare use case.

okay, but you can mark the average as no-cal if all the sources are no-cal, so that i can load a cal file after the fact... this is my workflow anyway, as i'm already having trouble to keep track of inputs and labeling while measuring, and i don't want to add another "do not forget" item... Also, i don't see why one would ever want to substitute an existing cal, unless it was an error.

Another question is, why is "dayton mic" measurement missing the change-cal button... maybe because i did a multi-input mode on just one input?... It is also missing phase data, probably for the same reason. I've attached the file, if you want to check it out.

Anyway, thank you very much for your replies, i can process my data manually.

 

[John Mulcahy]

The Dayton mic measurement was made with 2 channels selected, L and R. Both channels have the same data, so the result of the average is the same as a single channel measurement.

 

[DeepSOIC]

same data?... hmm, that raises some questions with my setup, it should in theory only be in the left channel. I'll check later.
