MPEG-4 Audio Layer
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.
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.
The format is available without any restrictions. It was created in 2002 by programmers of The Xiphophorus Company and given its name after a character from Terry Pratchett’s “Small Gods”. The format is intended for multimedia playing and editing; sampling frequency is 6-192 kHz. It was designed for live streaming with an option to store some tracks with their own tags within the same file. When the file is opened in a player, all tracks show, which gives the appearance of music being opened from different files.
Originally, it was used for the entirety of OGG-using files, but for the recent ten years, it has being associated mainly with files of OGG Vorbis. The function set is the same as one of AC3 and AAC codecs, which leave the popular MP3 behind. The spread of OGG is restricted a bit due to the fact that it is not supplied by Apple products.
At its core, the extension is a container for several streams of audio, video and metadata. It generates the sound of a medium or high level within the range of 16-128 kbps/channel and exceeds MP3 by sound quality. In order to reduce the file size, the program deletes a certain amount of data, and therefore, the compression is irreversible. The format is best suited for storage of musical tracks, but it can be used as well for voice recording.
