For everything after the recording stage: hardware/software and how you use it.

Not with the calibration file, no. But that's how it works.

Reliably fallible.

A mic calibration file is just a text file, with some numbers in it. First column is frequency, second column is gain in dB. An EQ file should be the same, but it can contain more finely grained settings. You might need to strip out some to use it with other EQ software.

Unless they've "invented" some custom format, they can't prevent you from using the calibration file with any other software. And if they did, it's just another company to avoid at all cost...

Each Sonarworks XREF20 measurement mic has its own calibration file, which by default is supplied in its own SWMIC format to be directly loaded into the Reference 4 Measure software, where it displays the response (here's mine for instance):

However, the calibration files can also be downloaded from this page, where they are supplied as a zip file containing both the .SWMIC and standard. txt format for inclusion into other software e.g. Room EQ Wizard etc.)

Hope this helps!

That sure helps, Martin!

Does it also work in the other direction? Can SonarWorks read a .txt cal file for another mic?

BTW. The internet has never heard of "SWMIC format"...

.SWMIC = Sonarworks mic format I presume.

Yes, it can, as long as it only contains a basic table of frequency and level information. Any other data must be stripped out, as described here:

https://support.sonarworks.com/hc/en-us ... /207211709

Essentially:

"You can also use your own omnidirectional measurement microphone with a calibration.

To do so, you will need to convert your calibration file so our measurement software can import it.

Calibration files are usually supplied in formats like .cal or .txt

Open up this file with any text editor and remove anything that is not the values for Frequency Response and Magnitude."
