M4A is short for MPEG-4 Part 14 and the file type was created by Apple in 2004 using the QuickTime File Format. The iTunes store runs on M4A file downloads (15 billion files worldwide). It is a digital multimedia container format used to store audio components, but can store other data (e.g. images) as well. Like most audio file types, there is a lossy compression option and it is accomplished using AAC encoding. Unlike other audio files there is a lossless compression available, which is possible due to the Apple Lossless format.
M4A is a file extension for an audio file encoded with advanced audio coding (AAC) which is a lossy compression. M4A was generally intended as the successor to MP3, which had not been originally designed for audio only but was layer III in an MPEG 1 or 2 video files. M4A stands for MPEG 4 Audio.
Both M4A and MP3 file extensions are used for audio-only files. Audio-only MPEG 4 container files usually have an M4A file extension. M4A files are unprotected. Protected files usually have an M4P file extension.
M4A files are an improvement on MP3 files primarily due to the fact they are capable of being lossless, as opposed to the lossy competition. This means the files can be converted back and forth from the original audio file and file size. MP4 copying is restricted using the DRM technology but the M4A file type is easier to distribute and copy. This explains why the Apple store uses M4A files, to allow users to purchase audio and transfer the content to CD's or mobile music players. Strictly an Apple product, it can be difficult to utilize the files in Windows. However, iTunes for Windows makes it possible, as well as converting the files to a Windows compatible audio file (which will cause lossy compression).
