APEv2 Tags at the end of a wave file

Hi all.

New user here, and have been in the radio industry for over 20 years, and am a developer as well.

I have a problem that I'm trying to solve, and I don't want to have to go and write some code as a solution if I don't have to.

Amongst the various audio tools for my job, one of them is called StationPlaylist. It's great and does the job for audio playback.

It stores it's various metadata in a couple of ways, internally on it's own database, but also in the files it plays, stored in the APEv2 format. This shouldn't be confused with the ID3v2.3 metadata tags as well, because the ID3 tags are not customisable. I need to read and write specific tags.

I have no problems reading and writing this format in MP3 files, but when it comes to PCM WAV (and a few others), this is where I come unstuck.

I have looked at various source code and programs that people have developed, with none of them compiling or being available for use in a .NET project, where none of them can read or write APEv2 at the end of a WAV file.

I need to be able to write non-standard tags.

Does anyone have any solution or point me in the direction where I do this?

Apparently ffmpeg is able to, but I didn't have any luck with it.

Monkeys Audio is now free, with the SDK released, but once again, I haven't had much luck with that too, even with just simply compiling it.

I'm ideally after either a small external program where I can run something like the following:

\> program.exe filename.wav -addape "title":"custom title"
\> program.exe filename.wav -removeape "title"
\> program.exe filename.wav -deleteape "title"

Or a set of functions in that I can integrate in to my program (which I'm thinking I'll have to write).

I have looked all over the place, but I haven't found anything that works specifically as yet.

Sorry for the long post on my first time, but I thought I would see if anyone else knows of anything.
Thanks in advance.

Apologies, maybe I should have posted this in the "Lossless / Other Codecs" section.... but maybe not?
and now I can't delete/move this post.

Absolutely nothing I know much about, but:
Once upon a time, the author of (which writes APEv2 "sidecar" files sans artwork) started out this thing: .  See also Tag (at the bottom).  Which were then developed further using WavPack's APEv2 writer it seems:

It does support .ape - but that might not be what you want? Oddly enough not WavPack.

Thanks for those suggestions, I'll take a look. They look promising just on the descriptions. I'll keep you posted.

Update. After chasing down a rabbit hole a whole bunch of links on, I've finally settled on Tag.exe by Case, and wherever else contributed to it.
I attempted to build it from source, and gave up. But, as with old code, the current binary files seem to be working fine.
Anyway, thanks heaps. I think this will solve my problem. :D
