What Is an M4A File?
M4A is AAC audio in an MP4 container — the format of iTunes purchases and iPhone voice memos. It sounds better than MP3 at the same size. M4A is a lossy format: it makes files small by discarding detail that is hard to notice. Converting it to another format cannot bring that detail back.
