What Is M4A – Definition of M4A
M4A is an audio-only MPEG-4 file. The official extension of MPEG-4 file is MP4 which contains both video and audio data, but when it only contains audio, then it uses the M4A file extension. M4A format is widely used by Apple for unprotected music downloaded from their iTunes Music Store ( DRM protected music uses M4P extension). Audio within the m4a file extension is typically encoded with AAC lossy compression, though lossless ALAC may also be used. In general, compared with MP3, the quality of M4A is better and its file size is smaller than MP3 file.>> See AAC vs MP3 ; M4V vs MP4 ; YouTube to FLAC What mp3 download.
