I recently updated the latest version of this issue, and I had no problems writing back in the early days

Hi @mrdong916 , sorry for the delay.
Could you send me the .m4a file please?
Thank you

I think it is a duplicate of issue #7.
I tried with other .m4a files and it works.
I found this issue on the original jaudiotagger repo which charge the YouTube downloaded file of this problem (as for the mp3 files, they seems to not be well formed).

As I answered in that issue I tried converting the file using ffmpeg and after that it works.
The problem is with the specified file.
I used this command

ffmpeg -i "姚六一 - 雾里-1.m4a" -c:a aac -vn "姚六一 - 雾里-1-changed.m4a"

@Samurai016 Is it possible to provide tag editing for other audio formats too? I do get your point that we can use FFmpeg to convert audio to mp3 and then edit the tags. But, it's not a proper solution, just a workaround to the problem. Also, If you have used FFmpeg, then you might be familiar with the increase in app size. So using FFmpeg to convert audio, just coz I want to edit tags isn't the best approach. Instead, I would prefer not to edit tags at all.
So, I would like to request you to add an option to edit tags for other formats too, which aren't mp3.

Are .m4a files supported?
