The M4A format is the standard audio format used within an MPEG-4 video stream and was introduced in 2001. M4A files use a lossy compression method to enable small files without noticeable loss of quality, with the compression rate being defined using an audio bitrate.

The format has gained popularity since its launch and is a common format for distributing music via online app stores. The file format is binary in nature and is usually unencrypted. The M4A format is supported by most popular music and audio editing software.
