ffmpeg - What is the difference between M4A and AAC Audio Files? -

-

is there difference between m4a audio files , aac audio files or same thing different file extension ?

.m4a files typically contain audio , formatted mpeg-4 part 14 files (.mp4 container).

.aac not container format , instead raw mpeg-4 part 3 bitstream audio stream encoded.

note m4a not have contain aac audio, there other valid options well.
