Metadata tags are not written to certain MP3 and WAV files from within ProppFrexx applications - both OnAir v3, OnAir v4, Medatada Editor v3 and Tagger v4 in both 32-bit and 64-bit variants - and we can not determine what type of file/data error causes this behaviour.
Users either enter metadata in the TAG Editor window, press "Save Metadata Tags" and "Save" again or the PFL-Player to set event data and close it after clicking "Save Metadata TAG". When "(Re)Read Medatata TAGs" is invoked, newly set cue points disappear. The file modification date is also not updated. External applications, such as Kid3, are able to modify tags.
The following did not solve the issue for the test .mp3 file:
- re-encoding files to another format within ProppFrexx OnAir (clicking Selection > Convert To ... in the playlist context menu)
- removing non-standard tag frames and ID3v1 tags and preferring ID3v2
- removing unsupported or incomplete data streams with MP3 Diags
Multiple threads (here and here) show that this library is rather "picky". Can you test the file for us and tell us how to repair it?
