For what it's worth, both files play properly and I get the following metadata
on both files under OS X 10.10.4

Perhaps the odd 12,000 sample/s rate is hosing it up?

Subject: Re: [wsjt-devel] WAV files not compatible
Hi Mike,
the WAV file format is a royal mess. Those TAG fields you cite are ID3 fields
and WAV format does not support ID3 at, officially. It is a tag format for MP3
files. Some tools do write ID3 tags to WAV files but they do it by writing it
into the sample data. We don't want that as it is corruption of the audio
stream.
There is a metadata format for WAV files named LIST-INFO that is supposedly
supported and it does work OK on Mac and Linux but Microsoft who invented it do
not support it. I am using LIST-INFO which has a whole bunch of pre-defined
tags listed here:
http://bwfmetaedit.sourceforge.net/listinfo.html
There is also BWF which is a Standard meant to clear up this mess which I have
included support for but it currently is not being written to the WAV files
(the 'bext' or Broadcast Extension chunk) since that too is not supported by
Microsoft.
Anyway, as I said it is not the tag metadata that is causing the problem, I
tried a file with no tag metadata at all an it is not readable by WMP so there
is a problem elsewhere. Looking into it right now...

Why not abuse the already-existing fields?
e.g.
Artist = call sign
Track Title = freq, dxcall, dxgrid
Album Title = WSJT-X version
Genre = mode
Or something like that.

Hi Mike,
ouch, I sort of expected something like this as Windows is appalling on
WAV file metadata which is a PITA considering WAV is a Microsoft format :(
Are you saying Windows File Explorer is seeing the files differently or
are you saying that a media player is not recognizing them. If the
latter which media player?
Can you check if Audacity can still recognize them and play them.
