About the formats
.m4a
M4A is audio stored in an MP4 container, usually AAC. It's what iPhone voice memos, iTunes purchases and many recorders produce.
.aac
AAC is the audio codec behind iTunes, YouTube and most MP4 videos. It sounds better than MP3 at the same bitrate, but bare .aac files aren't accepted everywhere.
