Both formats, briefly
AACIN
AAC was designed to succeed MP3 and generally sounds cleaner at the same bitrate, especially at lower settings. It is the audio riding inside most MP4 video, the default in Apple's music apps, and standard in digital radio and television. Choose AAC when you want a smaller file than MP3 without hearing the difference.
M4AOUT
M4A is an MPEG-4 container holding audio and nothing else, nearly always AAC and occasionally Apple Lossless. It keeps chapter marks, artwork and bookmark positions, which is why audiobooks and podcasts lean on it as much as music does. When a player rejects an M4A, converting to MP3 is the usual fix.
