M4A files are MPEG-4 Audio. This file type is used to store excellent quality audio content. When compared to MP3, M4A offers higher sound quality with efficient compression. It is well-known for being linked to iTunes, but it is also used in other platforms as well.
 
 M4A files work by storing audio data in compressed/uncompressed forms. The most common encoding methods in M4A files are AAC codec and Apple Lossless Audio Codec. AAC is lossy compression, that minimizes the file size without severely sacrificing quality. Conversely, ALAC is without any loss in quality, ensuring no audio is lost, but the file size is bigger.
