What is a MP3 file?
MP3 made digital music mainstream and remains the most compatible audio format in existence. Its lossy compression shrinks audio to roughly a tenth of its original size while keeping quality most listeners can't tell apart from the source.
What is a M4A file?
M4A is the audio-only MP4 container, usually carrying AAC audio — the format of iTunes purchases and Apple Voice Memos. Quality per megabyte beats MP3, though some older players won't take it.
Why convert MP3 to M4A?
MP3 is already compressed, so it's mostly converted when an editor, sampler or system demands raw WAV audio. M4A (AAC) sounds better than MP3 at the same bitrate and is native across Apple devices.
