WavPack files can store the MD5 checksum of the audio, if you encode with -m.
But it looks like Mp3Tag doesn't show it. Or is there a way to do it? It would be easiest if it just displayed it like it does for FLAC files, using %\_md5audio%.

If you have an example file that has this checksum tag, load it into mp3tag. When selected, open the Extended Tag window (use Alt+T) and see if that list includes it. If it is there, you can find out what the field is, and add it the column to the browse window and/or the Tag Panel.
If you could post a screenshot of that window, it would be helpful to identify this field.

The Extended Tags window doesn't show the audio MD5 checksum, I guess because it's not a "regular" tag.
It doesn't show it for FLAC files either, even though %\_md5audio% works in a column.
But, if it's there, you can see the MD5 of a WavPack file in [foobar2000](https://www.foobar2000.org/), for example (right-click, properties, details).

@georgeor
Would it be possible to provide such a WavPack file with MD5 checksum for test purposes?
Maybe with a Download-/Transferlink by PM?

Sure, here you go. Just rename the extension from .src to .wv.

Thank you for the test file.
I think, this Audio MD5 will be generated on the fly by Foobar2000:
If you open the file itself in a Editor, there is no obvious entry for a the value
`9B1BE87C6B579FDE2341515F4D82C008`
and it is different from the MD5 for the entire file:
`634435ec7939e7251b94adb59b9c70e7`
BTW:
If you use FFMPEG to analyze the file and generate the MD5 with
`ffmpeg -i "silence.wv" -vn -f md5 -`
you get (the interesting part):
```auto
Output #0, md5, to 'pipe:':

It's obviously different from the MD5 of the file, because this is the _audio_ MD5, not the _file_ MD5.
And it's not generated on the fly, it's part of the file and part of the WavPack spec when encoding with -m. FLAC is similar and you won't find the MD5 in plain hex text there either.
If you still don't believe me you can open this one in foobar (src-\>wv):
[silence - no MD5.src](https://community.mp3tag.de/uploads/short-url/jV6nhb3jXOF0EbHsP745ywP5xiw.src) (738 Bytes)
I admire a skeptical attitude, but I feel like we've gone a bit off track here... 😀

You convinced me with this second file. 👍 😉

Thank you for the suggestion and for providing example files. I've added support for `%_md5audio%` for WavPack with [Mp3tag v3.21h](https://community.mp3tag.de/t/455).
