| Description | The MP4 files (MPEG-4) are the multimedia files which are used with multiple stations and video players simultaneously, they can store video, audio and other suitable amounts of data subtitle even. MP4 file format is an extremely common file format due to its very own container format and it is also used with multiple platforms such as iTunes, PlayStation, and portable PSP as well. |
| Technical details | The technical details of MP4 files differ in great aspect and are unique as well, first released in 2001 under ISO/IEX 14496-1:2001 standards, it uses an AAC encoding to wear off unauthorized users from copying the data. The main purpose is the streaming rather than sending video or audio information. MP4 files can be used to store additional data such as text information, subtitles and still images while MPEG format can’t do this, anyhow the processing of data into MPEG-4 part 14 requires the use of private streams such as the use of hint tracks to include the information. |

MPEG-4 Audio Layer
| File extension | .m4a |
| File category | audio |
| Description | Apple Inc. has designed M4A format on the basis of QuickTime Fike. Now the format is being promoted in iTunes. It is a multimedia container intended for placement of sound components, as well as other data, such as images. MPEG-4 files may be stored with extensions M4A and MP4. In the latter case, they contain video as well. Alongside these sound formats, MPEG-4 allows for lossy compaction, through FFC Codec. However, it is possible to provide a lossless compaction thanks to Apple Lossless format. The files may be played on Windows PCs via iTunes, Windows Media Player 12, KSP Sound Player, Winamp and some other programs. With iTunes, the data can be converted into Windows-supported audio formats. |
| Technical details | In comparison with its predecessor MP3, M4A format provides with better sound quality and smaller file size. Thanks to lossless compaction, the data may be easily converted in both direction with no deterioration in quality. The sound data encoded with ACC compression, which reduces the file size considerably. Due to protection technology DRM, MP4 files cannot be easily distributed, while it is much simpler to replicate files in M4A; that is why “Apple Lovers” prefer the latter format. With M4A, it is possible to buy music in iTunes, as well as download it into smartphones or other devices. |
