What is M4A vs MP3?
M4A is an AAC-encoded audio file in an MP4-style container — Apple Music, Voice Memos, GarageBand, and podcast apps commonly use it, and it's generally more efficient than MP3 at the same bitrate. MP3 remains the most universally compatible lossy audio format, playing on essentially every device and piece of software ever made, including older car stereos and hardware MP3 players that don't recognize M4A at all.
