M4A files represent audio in the MPEG-4 format. They are used to store excellent quality audio files. In comparison to MP3, M4A files provide superior audio fidelity without increasing the file size. What makes M4A notable is its association with Apple's iTunes, but it is also used in other platforms as well.
 
 M4A files work by storing sound data in compressed/uncompressed forms. The primary encoding methods in M4A files are AAC codec and Apple Lossless Audio Codec. AAC uses a lossy method, that makes the file smaller while maintaining good quality. On the other hand, ALAC is completely lossless, preserving the original audio fidelity, even though the file is larger.
