The MP4 extension represents MPEG-4 format which can be used as a container for different types of media (Audio, Video, Subtitles, etc) individually or together. Popular as a video file format, this format is rarely used for audio files except for the Apple iPod and in iTunes store. AAC is the most common audio codec in this format, that delivers better sound quality than other formats. MP4 audio container supports variable bit-rates, subtitles and still images, making it a user-interactive audio format for both playback and editing applications.
