Tips: Distinctions Between M4A vs AAC Format

AAC stands for Advanced Audio Coding. It is an audio coding standard for lossy digital audio compression. AAC was developed to be a successor of MP3, and due to its small size and sound quality, it has gained popularity among many users. AAC achieves better sound quality than MP3 at the same bitrate, and it is therefore preferred for playbacks in audio players.

M4A is a file extension for an audio encoded with AAC. M4A stands for MPEG-4 Audio. M4A is usually used for audio-only files, and an audio-only MPEG-4 container has an M4A file extension. THE m4a files are unprotected. Protected files normally have an M4P extension.

The difference between AAC file and M4A file is that AAC is an audio encoding scheme while M4A is a file extension of AAC. M4a files contain audio only and are formatted as MPEG-4 part 14 files. (.mp4 container.) AAC is not a container format, but instead, it is a raw MPEG-4 part 3 bitstream with audio stream encoded. Besides, AAC encoded audio can have MP4, AAC and M4A extensions.
