M4A, Apple’s default audio format
iTunes, Apple Music, iPhone voice memos, and GarageBand record and export to M4A (an AAC container) by default. This format is well supported within Apple’s ecosystem but can cause playback problems on older car stereos, MP3 players, or software that only accepts MP3.
AAC versus MP3: better quality per bit, but less compatibility
At equal file size, the AAC used in M4A generally sounds better than MP3. MP3, however, remains the most universally playable format, which is why this conversion stays in demand despite M4A’s theoretically slight quality edge.
Useful for voice memos and tracks bought on iTunes
Voice memos recorded on an iPhone and tracks purchased on the iTunes Store are in M4A: converting them to MP3 lets you play them on a device or piece of software that doesn’t support this format.
