What is an M4A File?
An M4A file contains audio content encoded with either the Apple Lossless Audio Codec (ALAC) or Advanced Audio Coding (AAC) in the container format. It usually contains songs, podcasts, and maybe even audiobooks.
M4A files contain audio in the MPEG-4 format, which also supports different video, subtitle, and image formats. However, if only audio exists inside a file with the MPEG-4 format, it is saved using a .M4A extension. The compression to quality ratio of the MPEG-4 format is quite impressive, which is also why songs on iTunes are usually available in the M4A file format.
