Description | MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but can also be used to store other data such as subtitles and still images. M4A stands for MPEG 4 Audio and is a filename extension used to represent audio files. | A MIDI file does not contain any music, but instructions about music events and objects. The device interprets the commands in the MIDI file and reproduces the music-related events. The compact size of these files led to their widespread use in computers, mobile phone ringtones, webpage authoring and musical greeting cards. |
Technical details | Audio-only MPEG-4 files generally have a .m4a extension. This is especially true of non-protected content. M4A is often compressed using AAC encoding (lossy), but can also be in Apple Lossless format. | |
