M4A Format

M4A with the full name MPEG 4 Audio is a popular file extension used to represent audio files with better quality in lesser space, which can be imported into iPod and other portable device for playback.

File Format Description

M4A stands for MPEG4 Audio, it is a filename extension used to represent audio file. Files in .M4A format are actually the audio layer of (non-video) MPEG 4 movies. M4A is slated to become the new standard for audio file compression.

Apple Inc. first started using and popularizing the .m4a file extension, which is used for MP4 containers with audio data in the AAC or its own Apple Lossless formats. This is a new codec designed to provide lossless encoding in less storage space.

M4A Playback Problem

M4A is a multimedia container format used to store compressed audio and video data which contains audio encoded with either the Advanced Audio Coding (AAC) codec or the Apple Lossless Audio Codec (ALAC). M4A playback on Windows platform is not as easy as play WMA on WMP. Windows Media Player 11 requires the K-Lite Codec Pack in order to play M4A files. Windows Media Player 12 (included with Windows 7) provides native support for the M4A format. Of course you can turn to another media player which recognize M4A if you indeed meet a problem playback M4A songs, like VLC Media player, KMPLayer, etc. Alternatively, you can convert M4A to MP3 or WMA, etc.
