Aren’t AAC and m4a the same codec in different containers?

It’s really confusing.
The .m4a extension is commonly used for audio only MP4 (container) files. m4a files are capable of carrying other audio codecs other than AAC.
The .acc extension seems to mean very little. It indicates that the file contains a AAC stream but the container is not defined. Could be MP4, could be 3GP could be a raw AAC stream.

The concept of file extensions really break down when it comes to audio and video files
Honestly anywhere other than windows they start getting a bit funky since most ecosystems don’t actually rely on the filename to determine the file type
It also doesn’t help that so many file types are just a bunch of text files shoved into a zip file wearing a mask. It’s all abstractions all the way down baby!

Sure, but they used AAC to rocket to success, not MP3. In fact, it was annoying back in the day because everything non-apple used MP3.
