ALAC data is frequently stored within an MP4 container with the filename extension.m4a. This extension is also used by Apple for lossy AAC audio data in an MP4 container (same container, different audio encoding). The codec can also be used by the .CAF file type container, though this is much less common.
In 1996 Eric Kemp [clarification needed] proposed adding a 128-byte suffix to MP3 files, which would store useful information such as an artist's name or a related album title. Kemp deliberately placed the tag data (which is demarcated with the 3-byte string TAG ) at the end of the file as it would cause a short burst of static to be played by ...
Audio file icons of various formats. An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression.
A "tag" in an audio file is a section of the file that contains metadata such as the title, artist, album, track number, or other information about the file's contents. The MP3 standards do not define tag formats for MP3 files, nor is there a standard container format that would support
iTunes is a media player, media library, and mobile device management utility developed by Apple.It is used to purchase, play, download and organize digital multimedia on personal computers running the macOS and Windows operating systems, and can be used to rip songs from CDs as well as playing content from dynamic, smart playlists.
It allows information such as the title, artist, album, track number, and other information about the file to be stored in the file itself. The ID3v1 series, in particular, stores genre as an 8-bit number (therefore ranging from 0 to 255, with the latter having the meaning of "undefined" or "not set"), allowing each file to have at most one ...
For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint. First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs ...
Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The format was developed by Apple Inc. in 1988 based on Electronic Arts' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintosh computer systems.
