I tag audio files (\*.wav) with v3.08 on my PC (Windows10 Pro) and copy them to a USB stick and to the smartphone. On both devices (USB in the car), many of the tags are not displayed correctly (i.e. genre). Does anybody have a hint? TIA ---

The great question is: does you player support tags in wav files? A fair number does not. You could try flac instead. ---

Thank you for your time. The mystery is that on both devices (phone and stick), the tags work only in part, e.g. I have say 100 files tagged with genre "blues", the player on the phone finds 45, other genres appear 100% correctly. The stick does not even display certain items in the list of genres. This is why I think some of those tags are broken. All files had been (batch) tagged exclusively with the last 3 versions of Mp3tag. ---

Some players use the old conventions for the V1 standard for wav files. so it could be that some genres are user defined and not part of the original, byte-coded list. If you use the files with 2 different players, each may have its particularities that lead to your observation. If Mp3tag shows the tags alright, I would investigate further what the players make of it and not what the tagger does. ---

Is it possible you have some songs with 24-bit resolution? These may not be recognized or playable in some players. ---

Sorry for the late answer. I have checked, but all files 16-bit. ---

I think you have to continue to look for differences or patterns why you observe this behaviour. E.g. find a file that is OK on the phone but isn't on the stick. Or: filter for the files that have "blues" in GENRE and check whether it is really just "Blues" or e.g. "Blues " (with a trailing blank). The first could be part of the list of predefined genres whereas the one with trailing spaces would be a user-defined one which may not be supported by the player. ---

I think you are right on target. I do have several "hand-made" genres, some of which work OK with the smartphone but not with the car's reader. As for trailing spaces, I will check on this. Thank you again. ---

Unfortunately not yet familiar enough with Mp3tag to know WHERE in the application to apply this filter. ;o) ---

You do not have to remove all the superfluous spaces by hand, you can let MP3tag do the job: Select the filtered files. Converter\>Tag-Tag for GENRE Format string: $trim(%genre%) Click OK. You may repeat that procedure for other fields like ALBUM, TITLE, ARTIST - use the same filter and converter but replace GENRE with the actual new field name. ---

Thank you again. Guess I have got the hang of it in the meantime. Is there a dictionary of the possible commands somewhere? ---
