Is there a "standard" for tagging AAC ADTS/ADIF ? I see that mp3tag uses APEv2.
How common are the AAC ADTS/ADIF containers compared to mp4?
I guess they are very rare since nobody says anything?
ADTS isn't too common but appears sometimes in files with an extension of .aac
I've not seen any ADIF files in the wild.
They are usually tagged like MP3 files - ID3v1, ID3v2, APEv2, etc.
