- Playing Apple Voice Memos or iTunes audio on any device.
- Adding tracks to hardware that only supports MP3.
- Sharing audio that needs to play for everyone.
M4A vs MP3
M4A · MPEG-4 Audio (AAC)
M4A wraps AAC audio and is Apple's default (iTunes, Apple Music, Voice Memos). At the same bitrate it generally sounds better than MP3, though MP3 still wins on universal compatibility.
MP3 · MPEG-1 Audio Layer III
MP3 is the universal lossy audio format — it plays on practically every device, app and car stereo ever made. Files are small and quality at 192kbps+ is transparent for most listening.
