What is a M4A file?
M4A is AAC audio in an MPEG-4 container — the format used by iTunes and Apple Music, same quality as AAC with slightly better metadata support.
First released in 2001 by Apple / ISO, it uses lossy compression and no transparency, which makes it best suited to music purchased or downloaded from Apple services.
