Unable to write tags with Mp3tag to M4A that is being played

[Wineroz]

If a file in M4A format is being played in my Winamp, then I cannot write tags in it via the Mp3tag- I first have to stop the file in the player. But at the same time I can edit the tags within the Winamp itself

So is this a normal behavior for M4A files? With FLACs I do not have to stop the in Winamp in order to be able to change data in their tag fields


I am running Winamp 5.8 with Mp3tag 3.03 on Windows 10 Enterprise x64 18362.535. But I do not know what plugin is plugin my M4A files in Winamp, because under

Options > Preferences > Plug-INS > Input

I do not see any name / description with M4A in it

that's normal for really any file and that's because the file is locked as read-only when it's being used. When winamp writes the tag to the file it stops the song very briefly to write it then starts it again. I notice this when I change the ratings on songs

M4a is just a container. It can house different formats, like ALAC or AAC, etc

Really?

Sow how was is it then possible for me on Windows XP / Windows 7 with Winamp 5.666 and is possible for me on Windows 10 with Winamp 5.8 to change via Mp3tag data as I please in every kind of tag field [even a made up by me] of the following filetypes: FLAC, MP3, TTA, WAV, WV?

And also WMA does not seem to have an issue with that [but has limitation in regards to using certain signs in certain tag fields]

While on the other side along with M4A there is also APE, but that one has a problem even with "letting go of a file" - which only happens when Winamp is closed after its playback

I stopped using Winamp to write data in tags of audio files the moment I discovered Mp3tag, which must have been over 15 years ago - so I do not know about that

And... it means that the problem is with ALAC, ACC or some other format?

My NCH Switch Sound File Converter Plus that I use for creating sparse M4A files in its encoding option for that formats says "AAC / M4A Encoder Settings"; plus has an option to "Force MPEG Output". Thus... I do not know what kind of files am I really creating?
